Answer 32

Karyokinesis

Question 33

This is the organelle present in animal cells but not in plant cells.

Answer 33

Centriole

Question 34

It is a barrel shaped organelle located in the cytoplasm of animal cells near the nuclear envelope. It is the structural system of the cell.

Answer 34

Centrioles

Question 35

What are the phases of Mitosis?

Answer 35

PMAT

Question 36

The nuclear membrane and nucleolus begin to breakdown. The chromatins become double stranded and allow them to connect together. The spindle fibers are then developed.

Answer 36

Prophase

Question 37

The centrioles are in the opposite poles of the cell, and the nucleus are no longer present. The chromosomes line up in the middle of the cell.

Answer 37

Metaphase

Question 38

The centromere of each chromosome divides by the spindle fibers and moves towards the opposite poles. Cytokinesis begins as the cell membrane begins to form a cleavage. The nuclear membrane and nucleolus forms.

Answer 38

Anaphase

Question 39

Chromosomes reach the opposite pole and the spindle fiber disappears. The chromosomes uncoil and the nucleus reforms. The cytoplasm divides and a plasma membrane partitions the cell. Two daughter cells are formed.
