Flowering Plants

Question 1

The function of the root

Answer 1

Anchor and support the plant in the soil.
Take in (or absorb) water and minerals.
Some plants (e.g. yams) store food in their roots.

Question 2

The function of the stem

Answer 2

Support and hold up leaves and flowers
Transport water and minerals from the roots to the leaves and also transport food from the leaves to the roots
Some stems store food (e.g. potatoes)

Question 3

The function of the leaves

Answer 3

• Make food in a process called photosynthesis
• Allow gases and water vapour to pass in and out
• Some leaves store food (e.g. lettuce and cabbage)

Question 4

The function of the flower

Answer 4

The function of a flower is to produce seeds so that the plant can reproduce.

Question 5

The purpose of fruit

Answer 5

Protects seeds
Provides food for seeds

Question 6

The bud

Answer 6

Allows new flowers and leaves to grow

Question 7

The ______ transports water and minerals up the plant

Answer 7

Xylem

Question 8

transports food from the leaves

Answer 8

Phloem

Question 9

The loss of water vapour from the stomata of the leaves.

Answer 9

Transpiration

Question 10

The ______ are little holes on the underside of leaves

Answer 10

Stomata

Question 11

Answer 15

Carbon Dioxide

Question 16

From soil, enters through roots

Answer 16

Water

Question 17

From the sun. Absorbed by leaves due to their large flat surfaces. Provides energy needed to form food

Answer 17

Light

Question 18

Made by plants. It is a green pigment. Mostly found in the leaves. Absorbs light and allows photosynthesis to take place

Answer 20

Chemical Energy

Question 21

Food made by plant to provide energy in respiration, to form starch in parts of the plant and to form cellulose

Answer 21

Glucose

Question 22

Gas made by photosynthesis. Used for respiration to provide energy in the leaf. Released from the leaf into the air

Answer 22

Oxygen

Question 23

The change in growth of a plant in response to an outside stimulus

Answer 23

Tropism

Question 24

The way in which a plant changes growth in response to light

Answer 24

Phototropism

Question 25

The way in which a plant changes growth in response to gravity

Answer 25

Geotropism

Question 26

The controlled release of energy form food

Answer 26

Respiration

Question 27

requires oxygen

Answer 27

Aerobic respiration

Question 28

does not require oxygen

Answer 28

Anaerobic respiration

Question 29

Factors of respiration

Answer 29

• Glucose comes from the food we eat
• Oxygen is removed from the air we breathe

Question 30

Products of respiration

Answer 30

•We breathe out carbon dioxide & water vapour
• We use the energy throughout our day, walking, talking, thinking etc

Question 31

This type of respiration(anaerobic respiration) produces ________ which causes our muscles to cramp

Answer 31

lactic acid

Question 32

anaerobic respiration can also be carried out by microbes to produce useful products

Answer 32

The most common of these is in beer making, where alcohol has been produced from yeast feeding on glucose

Insect

Question 41

blows the pollen from one flower to another

Answer 41

Wind

Question 42

occurs when the male and female parts of the flower are ripe at the same time and when the pollen can fall onto the sticky stigma.

Answer 42

Self-pollination
