1

Stolon

Aerial hypha that allow the fungus to spread rapidly

2

Rhizoids

Provide extra surface area for absorption

3

Sporangium

Form spores

4

Saprophytes

Act as decomposers and hence, allow for mineral recycling

5

Flagella

Movement

6

Capsule/Slime layer

Protection

7

Plasmid

Contains genes that are responsible for bacterial resistance to antibiotics and are used in genetic engineering

8

Hyphae

Secretes enzymes into substrate, digests substrate & absorbs nutrients

9

Food vacuoles in amoeba

Kill and digest prey

10

Pseudopodia

Movement & Engulf prey

11

Contractile Vacuole

Eliminates water and prevents cell from bursting (Osmoregulation)

12

Roots

•Anchor the plant
•Absorb water & mineral salts from the soil ( by osmosis in root hairs )
•Store food in some plants

13

Meristem

A plant tissue capable of mitosis and hence cell production

14

Xylem

Transports water and mineral salts from the roots tot he leaves and gives support to the plant (due to lignin)

15

Phloem

•Sieve tubes transport food from the leaves to the rest of the plant
•Companion cells control the activities of the sieve tube elements

16

Red blood cells

Transport oxygen

17

What is the role of plasma?

Transports dissolved materials such as glucose, carbon dioxide and urea.
It also transports heat.

18

White blood cells

•Defend the body against infection
•Fight infections already present in the body
•Produce antibodies

19

Phagocytes

Attack bacteria by engulfing the bacteria and digesting them

20

Lymphocytes

Produce antibodies

21

Platelets

Clot the blood

22

Blood clots

•Prevent blood loss
•Prevent the entry of micro-organisms

23

Monocytes

Engulf bacteria

24

Monocytes

Engulf bacteria

25

Valves

Control the direction of blood flow, hence preventing the backflow of blood

26

What is the role of pericardial fluid?

Helps to reduce friction when the heart beats

27

Incisors

Cut and slice food

28

Canines

Tear and grip food

29

Premolars & molars

Crush and grind food

30

Fibre

Absorbs and stores water
