Do plants undergo mitosis or meiosis? ›

In plants, meiosis is initiated in sporogenous cells that are differentiated in ovules and anthers (Bhatt et al., 2001). In each ovule, only a single megaspore mother cell (MMC) surrounded by the somatic nucellar cells is differentiated and then undergoes meiosis (Figure ​1).

Yes, plants go through mitosis and meiosis both. During their vegetative growth they undergo mitosis and during sexual reproduction (for the production of spores) they undergo meiosis.

All eukaryotic organisms—including aquatic plants and algae—grow through the process of mitosis. Mitosis is a process where one cell divides into two cells (Fig. 2.46). Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information.

Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).

Plants that practice sexual reproduction use mitotic cell division when increasing the diploid vegetative parts of the plant like stem, leaf, and root, but use meiotic cell division to initiate the haploid stage of the plant that ultimately results in production of egg and sperm cells central to sexual reproduction.

So when the sperm gametophyte fertilizes the egg gametophyte, it results in a diploid zygote. From here, the zygote can undergo mitosis as usual to form more sporophytes. Both plant and animal cells generally undergo mitosis and meiosis in similar ways.

Plant cells divide in two by constructing a new cell wall (cell plate) between daughter nuclei after mitosis. Golgi-derived vesicles are transported to the equator of a cytoskeletal structure called a phragmoplast, where they fuse together to form the cell plate.

Meiosis is a process that happens in all animals and plants. Although the ultimate outcome, gametes with half the number of chromosomes as the parent cell, is the same, the detailed procedure is not. Meiosis creates gametes directly in mammals.

Meiosis occurs in all animals and plants. The end result, the production of gametes with half the number of chromosomes as the parent cell, is the same, but the detailed process is different. In animals, meiosis produces gametes directly.

So, the correct answer is 'Bacterial cell'

Is mitosis in plants or animals? ›

Thus, in mitosis, a single cell divides into two daughter cells. Therefore, all eukaryotic plant and animal cells undergo the process of mitosis. The outcome of the process is two new cells that contain the same number of chromosomes as in the first or original cell, and this is common for both plant and animal cells.

Meristems are regions in plants in which mitosis takes place.

All somatic cells divide by mitosis to maintain their chromosome number; hence, they never divide by meiosis. Only germline cells undergo meiotic cell division.

Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

Diploid sporophyte cells undergo meiosis to produce haploid spores. Each spore goes through mitotic divisions to yield a multicellular, haploid gametophyte. Mitotic divisions within the gametophyte are required to produce the gametes.

Answer and Explanation: Animal cells undergo meiosis because meiosis results in the formation of haploid gametes that are utilized in the process of sexual reproduction to form the diploid zygote. Sexual reproduction is one of the vital reproduction processes which aids in the development of a new life.

Mitosis is required for asexual reproduction, vegetative propagation in plants and is also responsible for the repair and regeneration of damaged tissues. Mitosis helps in maintaining the purity of the genome as no recombination or crossing over takes place.

In flowering plants, meiosis occurs in both the ovules in the plant's ovaries and in the anther sacs at the end of the flower's stamens. The anther sacs produce the male gametes of the flower while the ovules produce the female gametes.

Meiosis is a process that happens in all animals and plants. Although the ultimate outcome, gametes with half the number of chromosomes as the parent cell, is the same, the detailed procedure is different.

Meiosis is important for three main reasons: it allows sexual reproduction of diploid organisms, it enables genetic diversity, and it aids the repair of genetic defects.

What process do plant cells divide? ›

For plant cells to divide, a new cell wall must be built to create two cells from one. The process of building a new cell wall to separate the dividing plant cell is called plant cytokinesis. Figure 1 - Cell walls separate plant cells.

Nerve cells do not divide as they do not contain centrioles so why does plant cells divides even they do not contain centrioles?

Haploid organisms don't undergo meiosis except in the zygote stage.

Mitosis is different in plant and animal cells by the way cytokinesis takes place in them. In animals, cytokinesis takes place through the formation of a furrow in the plasma membrane whereas, in the case of plants, cytokinesis takes place through the formation of a cell wall.

Skin cells, red blood cells or gut lining cells cannot undergo mitosis.

The process of mitosis takes place throughout the body of an animal. But in plants, mitosis occurs mainly at the growing tips and the lateral sides. Mitosis in the growing tips of shoots and leaves helps in lengthening and mitosis at the lateral sides help in increasing the girth of the plant.

Plant cells do not have centrioles and their mitosis is frequently likened to the chromosome-based mechanism seen in acentriolar animal cells.

Unlike in the plant and animal cells where both mitosis and meiosis can be seen, the bacterial cells do not divide through mitosis or meiosis.

Almost all of your body's cells divide by mitosis. Meiosis is used to produce only one type of cell, and those are the gametes. During meiosis, a diploid cell divides to produce four, non-identical haploid daughter cells, each containing a single set of chromosomes.

Depending on the type of cell, there are two ways cells divide—mitosis and meiosis. Each of these methods of cell division has special characteristics. One of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes.

Which type of cells do not undergo mitosis and why? ›

The body cells that do not undergo mitosis are germ cells.

The germ cells are the reproductive cells (egg in the female and sperm in the male) and undergo meiosis.

Meiosis is a special kind of cell division, also called as reduction division, which occurs in germ cells or sex cells of male and female reproductive organs of plants and animals.

Most of the plants we are familiar with, like trees, grasses, and tomatoes, have a dominant sporophyte stage, so the visible plant is diploid. Just like humans, plants also have specialized gametes that are haploid (n), which are found in their reproductive organs like flowers.

How is meiosis different in plants and animals? Animals directly produce gametes by the process of meiosis, whereas plants produce spores by meiosis. The spores produce a gametophyte and then it divides to form gametes.

Sexual reproduction in the fungi consists of three sequential stages: plasmogamy, karyogamy, and meiosis. The diploid chromosomes are pulled apart into two daughter cells, each containing a single set of chromosomes (a haploid state).

All the cells don't divide all the time in plants. Cells present in meristematic tissues have the ability to divide. The structurally and functionally specialised cells lose their ability to divide. Such cells aggregate together to attain a common function, and are termed as permanent tissues.

Neurons cannot divide because they lack centrioles. Each nerve cell has a specific place in our nervous system.

A chloroplast is an organelle that is only present in plant cells. It is a plastid that contains chlorophyll and is also where photosynthesis takes place.

The organelle that plays crucial role in plant cell division is the microtubule. Fungi and plant cells use different microtubule-organizing centers to organize their microtubules.

Mitosis is different in plant and animal cells by the way cytokinesis takes place in them. In animals, cytokinesis takes place through the formation of a furrow in the plasma membrane whereas, in the case of plants, cytokinesis takes place through the formation of a cell wall.

What phases do plants go through in meiosis? ›

Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

Meristems are regions in plants in which mitosis takes place. Apical meristems are at the tips of shoots and roots and contribute to increases in length.

Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

Plant cells can't be divided like this because they have a cell wall and are too stiff. Instead, a structure called the cell plate forms down the middle of the cell, splitting it into two daughter cells separated by a new wall. When division is complete, it produces two daughter cells.

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

Mitosis is the process that results in the formation of new cells. Cells undergo mitosis, therefore, as part of plant growth.
