Small particles of RNA and proteins found throughout the cytoplasm.

Question 10

What is the endoplasmic reticulum ?

Answer 10

Site where lipid components of the cell membrane are assembled as we’ll as proteins and other material exported from the cell.

What is the Golgi apparatus ?

Answer 13

The organelle in a cell that modifies,sorts,and packages proteins and other material.

Question 14

What is a lysosome?

Answer 14

Small organelles filled with enzymes that is basically the digestion of the cell.

Question 15

What are vacuoles?

Answer 15

Structures that store material such as water , sugar, carbohydrates, etc.

Question 16

What is a mitochondria ?

Answer 16

Organelles that convert chemical energy into food.

Question 17

What are chloroplasts?

Answer 17

Organelles that capture energy from the sunlight and convert it into chemical energy.

Question 18

What Is a cytoskeleton ?

Answer 18

Supports the structure of the cell and gives the cell it’s shape.

Question 19

What are centrioles ?

Answer 19

Organelles that help organize cell division.

What is concentration?

Answer 22

The mass of solute in a given volume of a solution or mass/volume.

Question 23

What is diffusion ?

Answer 23

When particles tend to move to a area of more concentration to less concentration.

Question 24

What is equilibrium ?

Answer 24

When the concentration is the same throughout a system.

Answer 28

When the sugar solute is above strength.

Question 29

What is facilitated diffusion ?

Answer 29

When molecules cannot diffuse across the cell membranes lipid bilateral on their own move through protein channels.

Question 30

What is active transport?

Answer 30

When materials are moved the opposite direction against a concentration.

Answer 31

The eating of the cell.

Question 32

What is endocytosis?

Answer 32

The process of taking material into the cell.

Question 33

What is pinocytosis?

Answer 33

When tiny pockets along the cell membrane fill with liquid and pinch off to form vacuoles.

Question 34

What is exocytosis ?

Answer 34

When the membrane of the vacuole surrounding the material fuses with the cell membrane.
