Is the study of living things

Question 2

MRSFERG

Answer 2

M movement
R respiration
S sensitivity
F feeding
E excretion
R reproduction
G growth

Question 3

Movement

Answer 3

Animals can move from place to place

Plants do not move from place to place. They move when they grow or when a flower opens and closes its petals.

Question 4

Respiration

Answer 4

Respiration is the way living things get energy. They take in oxygen and mix it with food to get energy

Question 5

Nucleus

Answer 13

Normally round. It acts as the control centre of the cell. It has the DNA

Question 14

Cytoplasm

Answer 14

The watery liquid found between the nucleus and the cell membrane

Question 15

Mitochondria

Answer 15

Supply energy to the cell

Question 16

Cell wall

Answer 16

Found outside the cell membrane of a plant cell. Gives strength to the cell

Question 17

Vacuole

Answer 17

Space containing water, sugar and wastes - gives strength to the cell

Question 18

Chloroplasts

Answer 18

Contain chlorophyll to help make food using sunlight (photosynthesis)

Question 19

Invertebrates

Answer 19

Animals that do not have a backbone are called invertebrates

E.g. worm

Question 20
