Q

What happens during prophase?

A

Nuclear membrane disappers. Nucleolous disappears. Chromosome coils up. Spindle fibers attach from the poles to the chromosomes.

Q

What happens during metaphase?

A

The chromosomes line up in the equitorial plate. The spindle move them.

Q

What happens during anaphase?

A

The spindles pull the chromosomes apart and the centromial breaks and disappears.

Q

What happens during telophase?

A

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.

Q

What happens after the chromotin material coils up?

A

The asters in animal cells hold the centrioles in place which produce spindle fibers.

Q

Compare and contrast plant telophase with animal telophase.

A

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.

17
Q

During what stage does the aster disappear in animal Mitosis?

A

Telophase.

18
Q

What causes the Chromosomes to move apart during anaphase?

A

Spindles. The chromosomes do not move on their own.

19
Q

What is the difference between Mitosis and Meiosis?

A

Meiosis does not result in the same amount of chromosomes. Meiosis is sexual reproduction and Mitosis is asexual reproduction.
