In plants why is the mitosis the process that produces gametes instead of meiosis?
In plants, gametes are typically produced through a process called mitosis in the haploid gametophyte generation, which follows meiosis in the diploid sporophyte generation. The sporophyte undergoes meiosis to produce haploid spores, which then develop into gametophytes. These gametophytes then divide by mitosis to produce gametes, ensuring that the gametes remain haploid and are genetically identical to the gametophyte. Thus, while meiosis is crucial for generating genetic diversity in spores, mitosis is responsible for the production of gametes in the haploid phase.
What are the two ways fungi produce spores.?
Fungi produce spores through sexual reproduction, where two different mating strains combine genetic material to form spores, and asexual reproduction, where spores are formed through mitosis without the need for mating.
What cells divide by meiosis to produce male and female spores?
In plants, meiosis occurs in specialized cells called sporophytes, which are diploid. These sporophyte cells undergo meiosis to produce haploid spores—male spores (microspores) in the anthers and female spores (megaspores) in the ovules. In fungi, similar processes occur where specialized diploid cells, known as sporogenous cells, divide by meiosis to produce spores.
Does bread mold undergo mitosis and meiosis?
Bread mold undergoes both mitosis and meiosis during its life cycle. Mitosis is responsible for growth and asexual reproduction, while meiosis is involved in sexual reproduction to produce spores for genetic variability. Mold spores are then released to spread and germinate into new mold colonies.
Whats the main purupose of mitosis versus meiosis?
The main purpose of mitosis is to produce 2 identical daughter cells while the purpose of meiosis is for a cell to divide and produce 4 gamete cells that are necessary for reproduction.

Why must meiosis and mitosis be used to produce gametes?
Meiosis and not mitosis must be used to produce gamete. This is because meiosis produces spores that are used for reproduction and can form similar copies to the parent cell.
When spores go through the process of mitosis they produce?
When spores undergo mitosis, they produce identical daughter cells that are genetically the same as the original spore. This process can lead to the formation of new individuals, particularly in fungi and some plants, allowing for asexual reproduction. The resulting cells can develop into new spores or, in some cases, mature into fully developed organisms.
Are spores in the sporangia produced by mitosis or meiosis?
mitosis
Does bread mold undergo mitosis and meiosis?
Bread mold undergoes both mitosis and meiosis during its life cycle. Mitosis is responsible for growth and asexual reproduction, while meiosis is involved in sexual reproduction to produce spores for genetic variability. Mold spores are then released to spread and germinate into new mold colonies.
Must spores occur in mitosis?
Spores are produced through a specialized form of cell division called meiosis, not mitosis. Meiosis involves two rounds of cell division that results in the formation of haploid spores with half the number of chromosomes as the parent cell. These spores will eventually undergo mitosis to form new multicellular organisms.
What produces diploids?
Mitosis. All body cells must produce diploid cells, and therefore all body cells use mitosis to divide.
How do you briefly explain the growth stage of spore-producing organisms?
Growth of the organism happens by mitosis. Moisture helps the cells divide. However, the spores must also be attached to something that will provide food for them. They cannot produce their own food. When the spore has enough moisture and food provided for it, mitosis continues and the spore grows into an adult organism.
Why does your body use mitosis?
The body uses mitosis for growth, repair, and maintenance of tissues. Mitosis allows cells to divide and produce exact copies of themselves, ensuring that the body's cells have the correct number of chromosomes.
Are mold spores N or 2N?
the answer is N. Spores grow gametophytes that produce a haploid gamete through mitosis once fertilization occurs the product is a zygote that is 2n which will grow into a sporophyte that produces spores through meiosis.
