Question 5

What are cells?

Answer 5

Cells are the smallest unit that can carry out all of the functions of life.

Question 6

What are the functions of cells?

Answer 6

These functions include taking up nutrients and water, getting rid of waste, getting and using energy, and interacting with the environment.

Question 7

Where does a cell come from?

Answer 7

Cell division

Question 8

What separates the inside of a cell from the outside?

Answer 8

The cell membrane

Question 9

What is cytoplasm?

Answer 9

The jelly-like substance inside the cells, and all other parts inside that make up the cell.

Question 10

What are organelles?

Answer 10

Small compartments in the cell that have different structures and functions.

Question 11

What is the cytosol?

Answer 11

The jelly-like substance within a cell that suspends the inside parts of the cell.

Question 12

What is the nucleus?

Answer 12

Serves as an information database to store the cells genes.

Question 13

What do mitochondria do?

Answer 13

Act as factories to break down sugars and release energy that the cell can use.

Question 14

What are 4 features that plant cells and animal cells have in common?

Answer 14

They both have a:
-nucleus
-mitochondria
-cell membrane
-cytosol

Question 15

What is a cell wall?

Answer 15

A feature unique to plant cells. It is an extra layer around the cell which makes the plant cell more structured and stiff.

Question 16

What are chloroplasts?

Answer 16

An organelle unique to plant cells, which are what give plants their green color. Chloroplasts are the site of photosynthesis, which is how plants make their own food in the form of sugars.

Question 17

What are genes?

Answer 17

Genes are special instructions that a cell uses to carry out functions.

Question 18

How do mitochondria help the cell membrane carry out its function?

Answer 18

Mitochondria help break down sugars to release usable energy. Parts of the cell membrane then use this energy to move substances into and out of the cell.
