Flowering Plants

Question 1

Root

Answer 1

Anchor and support the plant in the soil. Take in or absorb water and Minerals. Some plants store food in their roots.

Question 2

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.

Question 3

Leaves

Answer 3

Make a process called photosynthesis. Allow gasses and water vapour to pass in and out. Some leaves store food.

Question 4

Flower

Answer 4

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

Question 5

Fruit

Answer 5

Protects seeds and provides food for the seeds

Question 6

The bud

Answer 6

The bud allows new leaves and flowers to grow

Question 7

Xylem

Answer 7

The xylem transports water and minerals up the plant

Question 8

Phloem

Answer 8

The phloem transports food from the leaves

Question 9

Transpiration

Answer 9

Transpiration is the loss of water vapour from the stomata of the leaves. It supplies water to the leaves for photosynthesis. Transpiration helps cool the plant.

Question 10

Stomata

Answer 10

The stomata are little holes on the underside of the leaves

Question 11

Factors that increase the rate of transpiration

Answer 11

Sun, wind, soil water, low humidity

Question 12

Photosynthesis

Answer 12

The process where green plants make food using light energy

Question 13

Why are plants and leaves green?

Answer 13

They’re green because they contain chlorophyll which is a green chemical needed for photosynthesis

Question 14

Chlorophyll

Answer 14

Found in chloroplasts in plant cells

Question 15

What part of the plant has the most chlorophyll?

Answer 15

The leaves and any green part of the plant have the most chlorophyll

Question 16

Photosynthesis word equation

Answer 16

Carbon dioxide + water (+ sunlight and chlorophyll) —> glucose + oxygen

Question 17

Carbon dioxide

Answer 17

Passes into leaves through stomata (found on the under side of a leaf)

Question 18

Water

Answer 18

From soil, enters through the roots

Question 19

Light

Answer 19

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

Question 20

Chlorophyll

Answer 20

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

Question 21

Glucose

Answer 21

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

Question 22

Oxygen

Answer 22

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

Question 23

Tropism

Answer 23

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

Question 24

Phototropism

Answer 24

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

Question 25

Geotropism

Answer 25

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

Question 26

Respiration

Answer 26

The controlled release of energy from food

Question 27

Aerobic respiration

Answer 27

Requires oxygen

Question 28

Anaerobic respiration

Answer 28

Does not require oxygen

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 and water vapour. We use energy throughout our day

Question 31

Anaerobic respiration in human muscles

Answer 31

Produces lactic acid, which causes our muscles to cramp

Question 32

Fermentation

Answer 32

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

Question 33

Nicole Thornton

Answer 33

A smelly Smurf

Question 34

The petal

Answer 34

Petals are used to attract insects into the flower; they may have guidelines on them and be scented

Question 35

The sepal

Answer 35

The flower is protected while it is in the bud by the sepals, these may be coloured green or have the colour of the petals. They are often brightly coloured to attract the insects.

Question 36

The stamen

Answer 36

The stamen produces the male gamete for fertilisation

Question 37

The carpel

Answer 37

The carpel produces the female gamete for fertilisation

Question 38

Pollination

Answer 38

Pollination is the transfer of pollen grains from one place to another

Question 39

Wind pollination

Answer 39

Blows the pollen from one flower to another

Question 40

Self-pollination

Answer 40

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
