Question 1

Define a eukaryotic cell

Answer 1

A eukaryotic cell is a type of cell that has a nucleus and membrane-bound organelles

Question 2

Define a prokaryotic cell

Answer 2

prokaryotic cell is a type of cell that hasn’t got a nucleus and membrane-bound organelles, usually found in bacteria and archaea

Question 3

What is an enzyme?

Answer 3

An enzyme is a biological molecule, typically a protein, that acts as a catalyst to speed up chemical reactions in living organisms

Question 4

What is mitosis?

Answer 4

Mitosis is the process of cell division in which a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell

Question 5

1) Interphase

Answer 5

The cell grows and prepares for division by replicating its DNA and organelles

Question 6

2)Prophase

Answer 6

Chromosomes condense, the nuclear membrane breaks down, and spindle fibers begin to form

Question 7

3) Metaphase

Answer 7

Chromosomes line up along the center of the cell, called the metaphase plate, and spindle fibers attach to the centromeres of each chromosome

Question 8

4) Anaphase

Answer 8

Sister chromatids separate and are pulled apart toward opposite ends of the cell by the spindle fibers

Question 9

5) Telophase

Answer 9

Chromosomes reach opposite poles of the cell, the nuclear membrane reforms around each set of chromosomes, and the chromosomes begin to decondense

Question 10

6) Cytokinesis

Answer 10

The cell membrane pinches inwards, dividing the cytoplasm and organelles into two separate daughter cells

Question 11

What is the order of the cell cycle?

Answer 11

1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telophase 6. Cytokinesis
