Unit 1 - Lesson 3

Question 1

Cytoskeleton

Answer 1

Is a network of protein filaments that give shape and support to cells

Also helps with cell division and movement

Question 2

Mitochondrion

Cellular respiration

Answer 2

The organelle where cellular respiration occurs. Called the “powerhouse of the cell”

The process where cells use oxygen to release energy stored in food

Question 3

Ribosome

Answer 3

Is the organelle that makes proteins by putting together chains of amino acids using instructions encoded in the cell’s DNA

Question 4

Endoplasmic reticulum

Answer 4

A system of membranes near the nucleus . Can be rough (has ribosomes) or smooth ( no ribosomes)

Helps in the production, processing, and transport of proteins and in the production of lipids

Question 5

Golgi Complex

Answer 5

The membrane-bound organelle that packages and distributes materials, such as proteins

Question 6

Cell wall

Answer 6

is a rigid structure that surrounds the cell membrane in plant cells

Provide support and protection to the cell

Question 7

Vacuole

Answer 7

A fluid-filled vesicle found in the cells of most animals, plants, and fungi

Plant cells have a large central vacuole that stores water and supports the cell

Question 8

Chloroplasts

Answer 8

Organelles where photosynthesis occurs

Chloroplasts are green because they contain chlorophyll.
Chlorophyll absorbs the energy in sunlight to make sugar

Question 9

Lysosomes

Answer 9

Organelles which contain digestive enzymes, which break down old organelles, waste and foreign substances in the cell

Question 10

Nucleus

Answer 10

The organelle that contains the genetic material (DNA) of the cell
