Selection 4:Golgi apparatus
Selection 5:endoplasmic reticulum
Selection 6:cell wall
9

Describe the function of each organelle.Nucleus

Answer:

The nucleus stores the cell’s DNA and controls the cell’s activities.

10

Describe the function of each organelle.Vacuoles

Answer:

Store water, nutrients, and waste; in plant cells, they help maintain turgor pressure.

11

Describe the function of each organelle.Cytoplasm

Answer:

The jellylike substance that fills the cell, supports the organelles, and is the site of many chemical reactions.

12

Which of the following did you remember?

A
The nucleus directs cell activity.
B
Ribosomes produce proteins for the cell. These proteins are then moved through the cell by the endoplasmic reticulum.
C
The Golgi apparatus packages and distributes proteins from the endoplasmic reticulum.
D
Vacuoles store water, waste products, food, etc.
E
Lysosomes break down waste material and debris.
F
Mitochondria break down sugar molecules to supply energy. Similarly, chloroplasts capture the energy from sunlight and convert it into chemical energy.
G
The cell membrane protects the cell and controls what enters and leaves it. The cell wall supports the cell membrane, maintains the cell’s shape, and protects the cell.
H
The cytoplasm supports and protects organelles in the cell.

14

Ribosome

Answer:

Ribosomes make proteins.

15

Lysosomes

Answer:

Break down cellular waste, worn-out organelles, and other materials using digestive enzymes.

16

Chloroplasts

Answer:

Organelles that use sunlight to make food for the plant through photosynthesis.

17

C ✔ cell membranecell wall cytoplasm

A
✔ cell membrane
B
cell wall
C

18

Endoplasmic reticulum

Answer:

The endoplasmic reticulum makes, processes, and transports proteins and lipids throughout the cell.

19

Mitochondrion

Answer:

Produces usable energy for the cell through cellular respiration.

20

Cell wall

Answer:

A rigid outer layer that supports, protects, and gives shape to the cell.
