1

Absorption

The transport of dissolved substances into cells

2

Digestion

The breakdown of absorbed substances

3

Respiration

The breakdown of food molecules with a release of energy

4

Excretion

The removal of soluble waste materials

5

Egestion

The removal of nonsoluble waste materials

6

Secretion

The release of biosynthesized substances

7

Homeostasis

Maintaining the status quo

8

Reproduction

Producing more cells

9

Cytology

The study of cells

10

Cell Wall

A rigid structure on the outside of certain cells, usually plant and bacteria cells.

11

Middle lamella

The thin film between the cell walls of adjacent plant cells

12

Plasma membrane

The semipermeable membrane between the cell contents and either the cell wall or the cell's surroundings.

13

Cytoplasm

A jellylike fluid inside the cell in which the organelles are suspended.

14

Ions

Substances in which at least one atom has an imbalance of protons and electrons.

15

Cytoplasmic streaming

The motion of cytoplasm in a cell that results in a coordinated movement of the cell's contents.

16

Mitochondria

The organelles in which nutrients are converted to energy.

17

Lysosome

The organelle in animal cells responsible for hydrolysis reaction that break down proteins, polysaccharides, disaccharides, and some lipids

18

Ribosomes

Non-membrane-bounded organelles responsible for protein synthesis

19

Endoplasmic reticulum (ER)

An organelle composed of an extensive network of folded membranes that performs several tasks within a cell

20

Rough ER

ER that is dotted with ribosomes

21

Smooth ER

ER that has no ribosomes

22

Leucoplasts

Organelles that store starches or oils

23

Chromoplasts

Organelles that contain pigments used in photosynthesis

24

Central Vacuole

A large vacuole that rests at the center of most plant cells and is filled with a solution that contains a high concentration of solutes

25

Waste vacuoles

Vacuoles that contain the waste products of digestion

26

Phagocytosis

The process by which a cell engulfs foreign substances or other cells

27

Phagocytic vacuole

A vacuole that holds the matter which a cell engulfs

28

Pinocytic vesicle

A Vesicle formed at the plasma membrane to allow the absorption of large molecules

29

Secretion vesicle

A vesicle that holds secretion products so that they can be transported to the plasma membrane and released

30

Golgi bodies

The organelles where proteins and lipids are stored and then modified to suit the needs of the cell
