Flashcards in Chapter 1.1 Cell Structure Deck (21):
1

A unicellular organism has

one single cell

2

A multicellular organism is made up of

many cells

3

The ultrastructure of a cell is its

fine structure as revealed at high magnification

4

Chloroplasts are present in

green plant cells

5

The nucleus of a cells contains

genetic material and controls cell activities

6

The cell membrane controls

the entry and exit of substances into and out of the cell

7

Cell organelles are

compartments found in the cytoplasm and are the site of chemical reactions

8

Bacterial cells do not contain

organelles

9

The cell wall is for

support and shape and prevents plant cells from bursting.

10

Plant, fungal and bacterial cell walls have different

structures and are composed of different chemicals

11

The vacuole stores a

watery solution of salts and sugars and helps to support cells.

12

Chloroplasts contain

chlorophyll and are the sites of photosynthesis

13

Mitochondria are the sites of

aerobic respiration in cells.

14

Ribosomes are the sites of

protein synthesis in cells

15

In bacterial cells, plasmids hold

some of the genetic material (DNA) of the cell.

16

Aerobic respiration is the

release of energy from food by a cell using oxygen

17

Cellulose

structural carbohydrate of which plant cell walls are composed

18

Cytoplasm is a

jelly-like liquid containing cell organelles and the site of many chemical reactions.

19

DNA is

Deoxyribonucleic acid; a substance in chromosomes that carries the genetic code of an organism

20

Mitochondrion is the

organelle that is the site of aerobic respiration and ATP production in cells

21

Protein is

a substance composed of chains of amino acids and containing the elements carbon, hydrogen, oxygen and nitrogen.
