What are the parts of a cell called?
Parts of a cell are called organelles.

What is the mitochondria?
Where energy is released during respiration.
2 of 19
What is the cytoplasm?
Where metabolic reactions controlled by enzymes take place.
3 of 19
What don't bacterial cells have?
A nucleus.
4 of 19
Are cell walls in yeast made of cellulose?
No.
5 of 19
Where are genes found in a bacterial cell?
In the string of chromosomes.
6 of 19
What is diffusion?
The spreading of particles from a region of high concentration to a low concentration.
7 of 19
How does oxygen diffuse into cells?
From a high concentration outside, to a low concentration inside.
8 of 19
Why is the concentration low inside the cell?
The cell keeps using the oxygen up, continuously.

What is muscular tissue specialized for?
To produce movement.
11 of 19
What do the cells in glandular tissue do?
Secrete (release) substances such as enzymes or hormones.
12 of 19
What do the cells in muscular tissue do?
Use energy from mitochondria to contract themselves.
13 of 19
Advantages of a multicellular organism?
Have many different cells that are specialized for a specific function.
14 of 19
What is a group of cells called?
A tissue.
15 of 19
What is the job of a pancreas?
Secretes pancreatic juice (containing enzymes) that breaks down starch, fats and proteins in food.
16 of 19
What do the salivary glands do?
Secretes saliva (containing enzymes) that break down starch in food.
17 of 19
What happens in the small intestine?
Where the enzymes from the pancreas work.
18 of 19
