Biology Chapter 5 Review

Front 1

cell

Back 1

Basic unit of structure for all living things

Front 2

Diffusion

Back 2

the movement of molecules or particles from an area of greater concentratrion to an area of lower concentration.

Front 3

Eukaryote

Back 3

cells containing membrane bound nuclei

Front 4

Organ

Back 4

A group of tissues that work together to perform a certain function

Front 5

Organelle

Back 5

The specialized structures in the cytoplasm of a cell that carry out special functions.

Front 6

Osmosis

Back 6

the diffusion of water across a semi-permiable membrane from a region of high concentration to a region of low concentration.

Front 7

Prokaryote

Back 7

Cells lacking distinct membrane bound structures; bacteria

Front 8

Organ System

Back 8

A group of organs that work together to perform a specific function.

Front 9

Tissue

Back 9

In multicellular organisms, a group of cells that are organized into functional unit; usually intergrated with other tissues to form an organ.

Front 10

Golgi Bodies

Back 10

Stacks of flattened membrane sacs that serve as a packaging prosessing center for products released from the cell.

Front 11

Concentration Gradient

Back 11

The difference in concentration between a region of high concentration to a region of low concentration.

Front 12

Facilitated Diffusion

Back 12

A process by which certain molecules diffuse quikly across the membrane.

Front 13

Osmotic Pressure

Back 13

The increase in pressure resulting from the flow of water in osmosis

Front 14

Isotonic Solution

Back 14

A solution that contains the same concentration of dissolved substances as does a living cell placed in it.

Front 15

Hypotonic Solution
Hypertonic Solution

Back 15

A solution that contains a lower concentration of dissolved substances than that of a cell placed in it. A solution containing a higher concentration...above.
