Do flowering plants go through meiosis?
Although the majority of crops are angiosperms in which meiosis occurs within floral organs, non-flowering plants have provided novel insights into the control of plant meiosis.
In angiosperms, meiosis takes place in sporogenous cells that develop de novo from somatic cells in anthers or ovules. A successful transition from the mitotic cycle to the meiotic program in sporogenous cells is crucial for sexual reproduction.
Yes, plants also undergo mitosis and meiosis similar to animal cells. Mitosis is required for growth, asexual reproduction and regeneration. Daughter cells produced by mitosis are identical to the parent cell.
The simple answer to it is yes. Meiosis is a process seen in plants as well as animals. The outcome of meiosis where gametes are produced with half the chromosome number as seen in the parent cell is the same.
Solution : Meiosis does not occur in asexually reproducing individuals.
Meiosis can take place only in a diploid stage (post-zygotic stage) because the zygote is the only diploid cell in the life cycle of such organisms.
Answer and Explanation: In flowering plants, mitosis occurs at the tips of roots and the ends of shoots. The tissue at these locations is called meristematic tissue. It contains meristem cells capable of cell division and differentiation into different types of cells.
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.
Mitosis takes place in somatic cells--all cells other than reproductive cells. Meiosis takes place in germ cells--reproductive cells, such as sperm and egg.
Plants are living organisms. That means they need to reproduce in order to pass on their genes to future generations. Plants can create offspring through either sexual or asexual reproduction.
In which part of a flower do both meiosis and fertilization occur?
Hence, it is proved that both meiosis and fertilization occur in the ovule.
Hence answer is 'hom*ologous chromosomes cross over'
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).
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.
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.
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.
Hint: All the parts of a flowering plant are diploid, That is stem, roots, leaves, branches etc. But in case of lower, different parts of the flower are either haploid or diploid. Complete answer: Having two sets of chromosomes in each cell, one set from each parent is known as diploid.
So, the correct answer is 'Bacterial cell'

Memory Tricks.
During the vegetative period of their life cycle (which may be as long as 120 years in some bamboo species), these plants may reproduce asexually and accumulate a great deal of food material that will be required during their once-in-a-lifetime flowering and setting of seed after fertilization.
Which part of the Apple flower are related to pollination or meiosis?
Answer and Explanation: 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.
After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.
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.
The pistil contains an ovary at its base in which female spores (called megaspores) will be produced by meiosis. The ovary is usually deep within the flower.
In flowering plants, meiosis is confined to specialized cells in anthers (microspore mother cells) and ovaries (megaspore mother cells). It is generallly easier to observe meiosis in anthers than ovaries because they have a greater proportion of meiocytes (cells undergoing meiosis).
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.
Abstract. Sexual eukaryotes generate gametes using a specialized cell division called meiosis that serves both to halve the number of chromosomes and to reshuffle genetic variation present in the parent.
Hence, it is proved that both meiosis and fertilization occur in the ovule.
Mitosis takes place in somatic cells--all cells other than reproductive cells. Meiosis takes place in germ cells--reproductive cells, such as sperm and egg.
Hint: All the parts of a flowering plant are diploid, That is stem, roots, leaves, branches etc. But in case of lower, different parts of the flower are either haploid or diploid. Complete answer: Having two sets of chromosomes in each cell, one set from each parent is known as diploid.
Are all plants asexual?
Plants are living organisms. That means they need to reproduce in order to pass on their genes to future generations. Plants can create offspring through either sexual or asexual reproduction.
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.
Through the process of meiosis, the sporophyte produces haploid spores in the flower. The spores are the gametophytic generation. 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).
