Where does meiosis occur in most plants?
In flowering plants, meiosis occurs in megaspore mother cells (megasporocytes) within the ovules of ovaries, and in microspore mother cells (microsporocytes) within the anthers of stamens.
Mitosis is a type of cell division which occurs in somatic or vegetative cells. In mitosis parent cell divides and forms two progeny cells. Both the progeny cells contain equal number of chromosome as parental cell, hence called equational division. Meiosis is a type of cell division which occurs in germ cells.
Meiosis occurs in the sporangia, which produces spores. If the spores germinate, the plant will form either an archegonium to produce an egg or an antheridium to produce sperm.
Meiosis creates sperm and eggs in animals, but it produces the gametophyte in plants. Megaspore mother cells (megasporocytes) within the ovules of ovaries and microspore mother cells (microsporocytes) within the anthers of stamens undergo meiosis in flowering plants.
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. Lateral meristems are responsible for increases in girth.
Meiosis occurs in sporophytes to produce spores. Mitosis occurs in gametophytes to produce gametes; meiosis occurs in sporophytes to produce spores; and the gametophyte is within the flower of angiosperms.
Meiosis is the reduction in chromosomes in the daughter cell due to the division of parent cell unequally. This type of division is seen in gametes and spores. Mitosis is the equal division of cells and is based on exact copying of the genetic material.
So, the correct answer is 'Bacterial cell'
Mitosis happens in all eukaryotic cells (plants, animals, and fungi). It is the process of cell renewal and growth in a plant, animal or fungus.
Meiosis occurs in Anther. In plants, meiosis occurs in the anthers to form pollen grains that is the male gamete, and within the ovary to form ovules. In meiosis a diploid cell divides in such a way so as to produce four haploid cells. These haploid cells form gametes.
How does meiosis differ in plant and animal cells?
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.
Final answer: Fertilisation occur in ovary of flowering plant.
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.
No meiosis can occur in haploid cells. A haploid organism (n) produces gametes (n) by mitotic division. These gametes (n) are then fused by fertilization to produce a zygote which is diploid. This zygote or diploid cell then undergoes meiotic division to again produce a haploid organism (n).
Mitosis, otherwise known as equational division, is a type of cell division that produces genetically similar cells with the same set of chromosomes. Cell division, likely known as mitosis, is required for plant growth, cell renewal, and asexual reproduction in a plant cell.
Meiosis is the kind of cell division that produces sex cells or the gametes. It takes place in the plant reproductive organs - anther and ovary.
1 Answer. It takes place both in somatic and reproductive cells of the plants and animals. In multicellular organisms, mitosis produces more cells for growth and repair. Mitosis division is responsible for growth and development of a single-celled zygote into a multicellular organism.
Meiosis occurs in the male flower parts to produce pollen (represented by the green circle) and the female floral organs produce egg cells (represented by the white circle). Spores grow by mitosis producing more haploid cells, this is the gametophytic generation.
In the typical flowering plant, or angiosperm, seeds are formed from bodies called ovules contained in the ovary, or basal part of the female plant structure, the pistil.
During pollen germination, the tube cell forms a pollen tube through the style to the bottom of the ovary, the generative cell migrates through it to enter the ovary for fertilization. During its transit inside the pollen tube, the generative cell divides to form two male gametes (sperm cells).
Which part of the Apple flower are related to pollination or meiosis?
The part of an apple flower that produces cells by meiosis is the sepal. The sepal of the apple flower produces pollen, which contains male gametes that are used to produce new seeds.
Meiosis is a process in which a single cell divides two times to produce four daughter cells, each with half as much genetic material as the mother cell. The number of chromosomes in these four daughter cells is half that of the parent cell. Meiosis is a process that happens in all animals and plants.
A specialized division of chromosomes called meiosis occurs during the formation of the reproductive cells, or gametes, of sexually reproducing organisms. Gametes such as ova, sperm, and pollen begin as germ cells, which, like other types of cells, have two copies of each gene in their nuclei.
In plant cells the cytoplasm is divided by the formation of a new cell wall, called the cell plate, between the two daughter cells.
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.
The key difference between plant and animal cell division is that plant cells form the cell plate in between the two daughter cells in mitosis, whereas the cell membrane forms the cleavage furrow in between the two daughter cells in animal cells.

What is the primary role of meiosis in plant cells?
Meiosis is the process of chromosomal reduction in eukaryotic cells (plants, animals, and fungi), which leads to the production of germ cells (gametes/sex cells) needed for sexual reproduction.
Both processes occur in four major steps: prophase, metaphase, anaphase, and telophase. Both animal mitosis and plant mitosis are followed by cytoplasmic division. During prophase, the chromosome condensation occurs in both animal and plant mitosis. The breakdown of the nuclear envelope occurs in the prometaphase.
In plants and animals
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.
