Flashcards in Biology Chapter 1 Deck (26):
1

Cell wall

Outer layer of plant cell, keeps it rigid

2

Vacuole

Centre of plant cell, full of sap

3

Chloroplast

Helps plant with photosynthesis, turns plant green

4

Microscope

An instrument to see specimens up close.

5

Specimen

An organism that is looked at.

6

Slide

What a specimen is placed on when it is looked at.

7

Cell

A blocks in organisms that makes up that thing.

8

Uni-cellular organisms

Organisms with one cell

A cell that has a particular job.

10

Diffusion

Gas particles spreading out from areas of high concentration to low concentration.

11

Rate of diffusion.

How quickly gas particles diffuse.

12

Binary fission

How uni-cellular organisms reproduce- splitting themselves in half
