1

Only fluids, gel-like, viscous

Cytosol

2

Cellular support and movement

Cytoskeleton

3

Selective permeability

Plasma membrane

4

Protein synthesis

Ribosomes

5

Lipid synthesis, detoxification

Smooth ER

6

Packages proteins and lipids

Golgi complex

7

ATP production

Mitochondria

Lysosomes

9

Forms mitotic spindle

Centrosome

10

Short-hair like structures on the surface of some cells

Cilia

11

Long cell projection used to propel sperm cells

Flagella

12

Chemical substances produced by cells; not bounded by a membrane

Inclusion

13

List threes principle parts of a generalized animal cell.

Plasma membrane, cytoplasm, nucleus

14

Name the two major types of molecules that make up the plasma membrane.

Phosphorus & proteins

15

Which of the the two makes up the majority of the membranes framework?

Phospholipids

16

These proteins extend across the plasma membrane, helping to move substances in and out of the cell, acting as recognition sites for hormones, or serving as enzymes to speed reactions.

Integral

17

These proteins are loosely attached to the surfaces of the cell membrane, serving as cytoskeleton anchors or cell identity markers.

Peripheral

18

What do mean when we say the cell membrane maintains an electrochemical gradient?

Difference in change

19

The movement of substances across a cell membrane using cellular energy (ATP)

Active

20

The movement of substances across a cell membrane using no cellular energy

Passive

21

Net movement of any substance (such as cocoa powder in hot milk) from region of higher concentration to region of lower concentration; membrane not required

Simple diffusion

22

Same as (a) except movement is across a semipermeable membrane with help of a carrier; ATP not required

Facilitated diffusion

23

Net movement of water from region of high water concentration. (Such as 2% NaCl) to region of lower concentration (such as 10% NaCl) across semipermeable membrane: important in maintaining normal cell size and shapes

Osmosis

24

Movement of molecules from high-pressure zone, as in response to force of blood-pressure.

Filtration

25

A solution that is hypertonic to RBCs contains ____ solute particles and ____ water molecules than blood

More, fewer

26

A solution that is ____-tonic to RBCs will maintain the size and shape of the RBC

Iso..isotonic
