Cells

Question 1

What are the 3 main parts of the Cell Theory?

Answer 1

-All Cells come from Pre-existing Cells
-Cells are the structure and function of all living things
-All living things are made of cells

Question 2

What is the order of the cell cycle?

Answer 2

-Interphase
-G1, S, G2
- Mitosis
- Prophase, Metaphase, Anaphase,
Telophase
- Cytokinesis
- Cytoplasm Divides

Question 3

What happens in Prophase?

Answer 3

-The nuclear membrane breaks apart
- The chromatin condenses into Chromosomes.
- The Centrioles form a star-shaped structure called the aster, and a spindle forms between them.

Question 4

What happens in Metaphase?

Answer 4

-The chromosomes line up in the middle of the cell, Along the equator
- Each chromosome attaches itself to a spindle fiber.

Question 5

What happens in Anaphase?

Answer 5

-The Chromatids are pulled apart by the spindle and move to opposite sides of the cell

Question 6

What happens in Telophase?

Answer 6

• Two nuclei are formed
• Spindle fibers disappear
• Chromosomes uncoil and become chromatin again
• Nucleus membrane reappears

Question 7

What happens in Cytokinesis?

Answer 7

The Cytoplasm splits into two daughter cells.

Question 8

What happens in the G1, S, and G2 phases of Interphase?

Answer 8

G1- Cell just being a Cell
S- Cell replicates its DNA for division
G2- The cell prepares its organelles and cellular components for division
