Where does mitosis and meiosis occur in plants?
Mitosis and meiosis occur in the nuclear region of the cell, where all the cell’s chromosomes are found. Nuclear control mechanisms begin cell division at the appropriate time.
Where does meiosis occur in seedless plants?
Meiosis takes place in a specialized structure on the sporophyte (the sporangium), producing spores (not gametes!). The spores divide and produce male or female gametophytes.
Does meiosis occur in plant cells?
In plants, however, haploid cells can literally have a life of their own. During that break, a separate little haploid plant grows. Gametophytes produce gametes by mitosis. In animals, meiosis produces sperm and egg, but in plants, meiosis occurs to produce the gametophyte.
Where does mitosis occur in plants?
Meristems
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.
Where do meiosis occur in 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.
Where does meiosis occur?
During fertilisation, two haploid gametes fuse to form one diploid cell. This will divide by mitosis to form an organism. Meiosis occurs in the testes of men and ovaries of women.
Where does meiosis occur in plants quizlet?
Meiosis occurs in spore production in the sporophyte generation of Plants, Fungi, and some Protists. One Parent alone produces offspring.
Where does meiosis occur in most plants?
Meiosis, a specialized cell division to produce haploid cells, marks the transition from a sporophytic to a gametophytic generation in the life cycle of plants. In angiosperms, meiosis takes place in sporogenous cells that develop de novo from somatic cells in anthers or ovules.
Where does meiosis occur in plants and animals?
Comparison to mitosis
Meiosis | Mitosis | |
---|---|---|
Where does it happen? | Almost all eukaryotes (animals, plants, fungi, and protists); In gonads, before gametes (in diplontic life cycles); After zygotes (in haplontic); Before spores (in haplodiplontic) | All proliferating cells in all eukaryotes |
Where does meiosis occur in plant and animal?
In animals mitosis occurs in somatic cells and meiosis in germ cells during gamete formation, in plants mitosis occurs in all except those which produce spores by meiosis.
Which of the following occurs during meiosis?
Synapsis and crossing-over occurs is the correct answer. Mitosis and meiosis are the two methods of replication of cells. Former is called equational devision while latter is called reducational division. Synapsis formation and crossing over occurs only during meiosis, because the method takes place only in sex cells.
Does meiosis occur in zygote?
In zygotic meiosis, the zygote acts as the meiocyte and meiosis occurs in diploid zygotes. Zygote represents the diploid sporophyte generation. The zygote undergoes meiotic division to form haploid spores and thus zygotic meiosis occurs in most algae. The haploid spores undergo mitosis to form haploid gametophytes.
