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

RESPERATION

Answer 4

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

Question 5

SENSITIVITY

Answer 5

~ Sensitivity is the ability to react to changes in the environment. Animals will run away from danger, a plant will grow towards light.

Question 6

FEEDING

Answer 6

~ Animals do not make their own food. They get their food by eating plants and other animals. Plants make their own food.

Question 7

PHOTOSYNTHESIS

Answer 7

Question 10

GROWTH

Answer 10

~ Result from cell devision.

Question 11

CELL MEMBRANE

Answer 11

~ Very thin layer that surrounds the cell. Holds cell contents in place and controls what passes into and out of the cell.

Question 12

NUCLEUS

Answer 12

~ Is normally round. It acts as the control centre of the cell. It has the DNA.

Question 13

CYTOPLASM

Answer 13

~ The watery liquid found between the nucleus and the cell membrane.

Question 14

MITOCHONDRIA

Answer 14

~ Supply energy to the cell.

Question 15

CELL WALL

Answer 15

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

Question 16

VACUOLE

Answer 16

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

Question 17

CHLOROPLASTS

Answer 17

~ Contain chlorophyll to help make food using sunlight (photosynthesis)

Question 18

INVERTEBRATES

Answer 18

~ Animals that do not have backbone are called *invertebrates.
e.g. worm

Question 19

VERTEBRATES

Answer 19

~ Animals that have a backbone are called *vertebrates.
e.g. dog
~ Vertebrates are normally bigger and more complex animals than invertebrates.
