Mitosis & Meiosis Flashcards
What are the phases of Mitosis?
Interphase, prophase, metaphase, anaphase, telophase
In which phase does the cell grow the most?
Interphase
Define Mitosis?
Cell division
What happens to the chromosomes during Mitosis?
The number of chromosome stay the same
What happens during interphase?
The centrioles and chromosomes are duplicated.
What happens during prophase?
Nuclear membrane disappers. Nucleolous disappears. Chromosome coils up. Spindle fibers attach from the poles to the chromosomes.
What happens during metaphase?
The chromosomes line up in the equitorial plate. The spindle move them.
What happens during anaphase?
The spindles pull the chromosomes apart and the centromial breaks and disappears.
What happens during telophase?
The spindles fibers disappear. The chromosomes uncoil. The nuclelous comes back and is duplicated. The nucleus is duplicated. the cell plate has split the cell in two.
What % is similar between animal & plant mitosis?
85%
Which stage of Mitosis is the longest?
Interphase
Until which phase is animal and Plant Mitosis the same?
The first part of prophase.
What happens after the chromotin material coils up?
The asters in animal cells hold the centrioles in place which produce spindle fibers.
What is duplicated during animal Interphase that is not created during plant interphase?
Centrioles.
What happens during plant metaphase?
The Spindles pull apart the chromosomes.
Compare and contrast plant telophase with animal telophase.
The Spindle disappear, the chromosomes uncoil. Nucleolus and Nucleus are duplicated in both. However, in plant telophase, the cell plate creates a rift from inside out. In animal telophase, the cell furrows from the outside in to separate.
During what stage does the aster disappear in animal Mitosis?
Telophase.
What causes the Chromosomes to move apart during anaphase?
Spindles. The chromosomes do not move on their own.
What is the difference between Mitosis and Meiosis?
Meiosis does not result in the same amount of chromosomes. Meiosis is sexual reproduction and Mitosis is asexual reproduction.
