Question 9

Define organelle

Answer 9

The tiny structures that make up cells

Question 10

What is the cell wall and what is its function?

Answer 10

A strong outward structure made of cellulose that provides support and protection for the plant. Allows some water, oxygen, carbon dioxide, and some dissolved oxygen to pass into and out of the cell.

Question 11

What is the cell membrane and what is its function?

Answer 11

Provides protection and support for the cell. Controls the movement of materials into and out of the cell. Keeps conditions homeostatic. In a plant cell, located inside the cell wall. In an animal cell, it for,s the outer covering.

Question 12

What is the nucleus and what is its function?

Answer 12

Controls all the activities of the cell, is the brain of the cell

Question 13

What is the nuclear membrane and what is its function?

Answer 13

Membrane that surrounds the nucleus and allows materials to pass into and out of the nucleus through pores

Question 14

What are chromosomes and what are their function?

Answer 14

Thick, rod like structures in the nucleus. Responsible for reproduction and growth of the cell. Responsible for passing on traits of the cell to new cells

Question 15

What is the nucleolus and what is its function?

Answer 15

Structure inside the nucleus where ribosomes are produced

Question 16

What is the endoplasmic reticulum and what is its function?

Answer 16

Tubed passageways leading out from the nuclear membrane that transports proteins

Question 17

What is cytoplasm and what is its function?

Answer 17

A clear, jelly like substance that is constantly moving and allows the organelles to float

Question 18

What are ribosomes and what are their function?

Answer 18

Grain like structures that are found attached to the walls of the endoplasmic reticulum, made in the nucleolus. Ribosomes make proteins that the cell needs.

Question 19

What are the mitochondria and what are their function?

Answer 19

Structures that supply most of the energy for the cell. Breaks down sugars into water and carbon dioxide into energy called atp

Question 20

What are vacuoles and what is their function?

Answer 20

Storage units that store water, food, and waste.

Question 21

What are lysosomes and what is

Their function?

Answer 21

Contain enzymes that break down large food molecules into smaller ones, and passes them on to the mitochondria

Question 22

What are chloroplasts and what are their function?

Answer 22

Green circular structures that contain chlorophyll which is used in photosynthesis.
