0

Function of the nucleus

Contains genetic information to control all cell activities

1

Function of the chloroplast

Site of photosynthesis

2

Function of the mitochondria


Site of aerobic respiration

3

Function of the ribosomes

Site of protein synthesis

4

Function of the rough ER

Transport of protein

5

Function of the Golgi apparatus

Processes and packages protein for secretion

6

Function of the lysosomes

Destroys unwanted material using digestive enzymes

7

Function of the centriole

Produces the spindle fibres in mitosis and meiosis

8

Function of the root hair

The hair shape provide an increased surface area
Absorption of water and minerals

9

Function of phloem

Cells have end wall pores allowing cytoplasm to connect
Transport of products of photosynthesis

10

Function of xylem

Cells are dead, thickened with lignin and with no end walls or contents

11

Function of palisade mesophyll

Contain many chloroplasts
Photosynthesis

12

Function of skeletal muscle

Contain many mitochondria to provide ATP for muscle contraction

13

Function of the goblet cell in trachea

Contain many Golgi
Secrete mucus to trap bacteria and other breathed-in particles

14

Function of red blood cell

Disc-shaped with dimples in each side to provide increased surface area

15

Function of a phagocyte

Have many lysosomes containing digestive enzymes
Engulf and digest invading bacteria

16

What is a unicellular organism

They are organisms with only once cell

17

What is a multicellular organism

An organism with multiple cells

18

What are the functions of the cell wall

Fully permeable
Provides support for plant cells
Expands to prevent bursting when plant cell is full of water

19

What is the cell wall made up of

Cellulose fibres in a criss-cross arrangement with large gaps

20

What is the plasma membrane composed of?

Protein
Phospholipid

21

What can denature a protein

Heat

22

What is diffusion

The movement of small soluble molecule from a region of high concentration to a region of low concentration along a concentration gradient

23

What is osmosis

Osmosis is the movement of water molecules from a region of high water concentration to a region of low water concentration

24

What is hypertonic

Hypertonic solutions have a lower water concentration

25

What is hypotonic

Hypotonic solutions have a higher water concentrations

26

What is an isotonic solution

Each solution has the same water concentration

27

What is active transport

The movement of molecules from low to high concentration. This requires energy
