Mitosis phases
What is the phase of mitosis where all of the chromatids are built but are just floating around in a cell?
Prophase
True or False: Binary fission results in genetic diversity.
False. Binary fission produces 2 genetically identical offspring.
What is the main advantage of binary fission?
Rapid reproduction and population growth.
Describe what happens during telophase?
Chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.
Which type of organisms primarily use binary fission for reproduction?
Prokaryotic organisms
Why is mitosis important for multicellular organisms?
Mitosis is essential for growth, tissue repair, and asexual reproduction in multicellular organisms.
What occurs during anaphase?
Sister chromatids are pulled apart and move toward opposite poles of the cell.
Describe the steps of binary fission?
1.DNA replicates
2.The cell gets long
3.The plasma membrane pinches inward
4.The cell splits into two daughter cells.
Why is binary fission considered a form of asexual reproduction?
Because it involves a single parent cell dividing into two identical daughter cells without the involvement of sexual organs.
What phase are the cells in most of the time?
Interphase
What is binary fission?
Binary fission is a type of asexual reproduction where a single organism divides into two equal parts, each becoming a new organism.
What is mitosis?
Mitosis is a type of cell division in which a eukaryotic cell divides to produce two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.
During which specific phase of mitosis do the chromosomes attach to the microtubules from opposite spindle poles, ensuring that each sister chromatid will be pulled to opposite ends of the cell?
Metaphase
How is binary fission different from mitosis?
Binary fission is a simpler process that occurs in prokaryotes, while mitosis is more complex and occurs in eukaryotes. Mitosis involves multiple stages and the formation of mitotic spindles.
How are chromosomes aligned during metaphase?
The mitotic spindles and the protein tubes align the chromosomes.
