Yes, they can occur. Mitosis is essentially a duplication process: It produces two genetically identical “daughter” cells from a single “parent” cell, whereas, Meiosis, on the other hand, shuffles the genetic deck, generating daughter cells that are distinct from one another and from the original parent cell.
What organisms use meiosis and mitosis?
Organisms which reproduce asexually cannot undergo meiosis, whereas all eukaryotic organisms undergo mitosis. Mitosis and meiosis are similar in that both can only occur in eukaryotic cells.
What type of cell can undergo both meiosis and mitosis?
1) Somatic cells undergo mitosis whereas gamete cells undergo meiosis. Mitosis takes place throughout the lifetime of an organism.
Why do some species use both mitosis and meiosis?
Why do some species employ both mitosis and meiosis, whereas other species use only mitosis? They need both if they are producing animal gametes. *The form of cell division that produces animal gametes is meiosis, not mitosis. The production of gametes in plants is a function of both mitosis and meiosis.
How are mitosis and meiosis similar and different?
Mitosis has only one round of cell division, while meiosis has two. … Mitosis produces daughter cells (diploid cells) that are identical to the parent cell, while mitosis produces haploid/monoploid cells that only have half of the normal number of chromosomes.
Where does meiosis occur in animals?
In animals this occurs in the gonads (ovaries in females; testes in males). In plants this occurs in the archegonia in females and in the antheridia in males.
What event occurs in meiosis but not mitosis?
The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Which cell can undergo meiosis?
In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
What is the major difference between mitosis and meiosis 1 in a diploid organism?
What is a major difference between mitosis and meiosis I in a diploid organism? Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis I.
What happens in both mitosis and meiosis?
Mitosis and meiosis both involve duplication of a cell’s DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells.
How does meiosis and mitosis build and maintain a complex organism?
In multicellular organisms individual cells grow and then divide via a process called mitosis, thereby allowing the organism to grow. … Cellular division and differentiation produce and maintain a complex organism, composed of systems of tissues and organs that work together to meet the needs of the whole organism.
Which of the following does not occur during mitosis?
Explanation: Crossing over is the only answer choice that does not occur during mitosis. Crossing over occurs during prophase I of meiosis and involves swapping of genetic information between homologous chromosomes.
How are mitosis and meiosis 2 similar?
The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.
How are mitosis and meiosis similar and different quizlet?
Meiosis is a type of cell division that produces four cells, each with half of the number of chromosomes as the parent cell. … Mitosis produces 2 identical cells, while meiosis produces 4. Meiosis are genetically different, while mitosis is genetically identical.
