Question 1

Includes everything between the plasma membrane and the nuclear envelope

Answer 1

Cytoplasm

Question 2

The nuclear envelope and its contents (includes DNA)

Answer 2

Nucleus

Question 3

Surrounds the cell, forms a limiting barrier between external and internal environments

Answer 3

Plasma membrane/Cell membrane

Question 4

Movement of substances through the cell membrane based on concentration differences (high to low)

Answer 4

Simple Diffusion (an example of passive transport)

Question 5

Movement of substances through the cell membrane against a concentration gradient

Answer 5

Active Transport

Question 6

Process by which large molecules are secreted from the cell

Answer 6

Exocytosis

Question 7

Process by which large molecules are brought into the cell

Answer 7

Endocytosis

Question 8

“cell eating” engulfment of large particles with membrane extensions

Answer 8

Phagocytosis

Question 9

“cell drinking”; ingestion of fluid and small particles

Answer 9

Pinocytosis

Question 10

Substances bind to receptors which stimulates the formation of an invagination and ultimately a vesicle is internalized

Answer 10

Receptor-Mediated Endocytosis

Question 11

Nonmotile; help increase the surface area

Answer 11

Microvilli

Question 12

Motile, move substances over the surface of stationary cells

Answer 12

Cilia

Question 13

Motile, whip-like structure that moves cells

Answer 13

Flagellum
