Biology 2.5 (Phases of a Cell)

Question 1

What is prophase

Answer 1

The beginning of cell division
- The chromosomes condense.
- The nuclear membrane disappears.
- Spindle forms

Question 2

What is metaphase

Answer 2

• Chromosomes line up in the centre of the cell (equator)
• Attached to the spindle fibers by thei centromere*

Question 3

What is anaphase

Answer 3

• The two identical chromatids split apart
• Spindle fibers pull chromosomes to opposing sides of the cell

Question 4

What is telophase

Answer 4

• Nuclear membrane re-forms
• Chromosomes unpack into chromatin

Question 5

What is cytokinesis (Not mitosis)

Answer 5

• Cell is divided into two parts
• (In animal cells) Cell membrane pinches in
• (In plant cells) New cell wall (made of cellulose) is formed between new cells

Question 6

What is interphase (not mitosis)

Answer 6

• The “normal” phase
• Growth phase
