Answer 1

Bacteria

Question 2

What is Glucose?

Answer 2

A carbohydrate

Question 3

A carbohydrate is used in a process. What is it known as?

Answer 3

Chemosynthesis

Question 4

Is glucose a product?

Answer 4

Yes

Question 5

Chemosythesis uses what as their source of energy?

Answer 5

Chemicals

Question 6

Give one reactant?

Answer 6

Carbon Dioxide

Question 7

The leaves of green plants absorb what from the light which originates from the sun?

Answer 7

Energy

Question 8

What do plants need for photosynthesis from the air arounf them?

Answer 8

carbon dioxide

Question 9

What are guard cells?

Answer 9

Guard cells arespecialised cells found in the leaves of green plants. They control the size of the stomata

Question 10

What are xylem tissues adapted to?

Answer 10

Xylem tissues is adapted to transport water containing dissolved mierals around plants.

Question 11

What are roots mostly needed for?

Answer 11

To absorb water from the soil

Question 12

What are yellow leavers an indication for?

Answer 12

an indication of a lack of chlorophyll or magnesium

Question 13

Where does photosynthesis mostly occur?

Answer 13

In the palisade cells

Question 14

What will happen if the plant is losing water?

Answer 14

The stomata will close

Question 15

What mineral does green plants need?

Answer 15

Mineral to male the pigment chlorophyll

Question 16

What is normally found in the soil which is from plants?

Answer 16

Nitrate ions

Question 17

Where is energy stored in a green plant?

Answer 17

Energy is stored in green plants as a chemical energy store

Question 18

What do Fertiliseres do?

Answer 18

Fertilisers contain a range of minerals to help the plant grow strongly.

Question 18

What is carbon dioxide needed for?

Answer 18

The gas carbon dioxide, found in the atmosphere, is needed by plants for photosynthesis.

Question 19

What happens if the air around the plant is very dry?

Answer 19

If the air surrounding a plant’s leaves is very dry, the air bubble will move faster along the glass tube.

Question 20

what do green plant absorb?

Answer 20

Green plants absorb energy from sunlight.

Question 20

Where is most of the water vapour lost from?

Answer 20

the leaves.

Question 21

Where do terrestrials get there nutrients from?

Answer 21

Land-living (terrestrial) plants get their nutrients from the soil in which their roots grow.

Question 21

What is photosynthesis?

Answer 21

Plants transform energy from the Sun into stored energy in their leaves by a process called photosynthesis.

Question 22

What is the gas oxygen?

Answer 22

The gas oxygen is the waste product of photosynthesis.

Question 23

The gas exchange area of leaves is greatly increased by the presence of internal air spaces. True or false?

Answer 23

False

Question 24

When is most oxygen let out?

Answer 24

Green plants photosynthesise during the hours of daylight. Most oxygen is released at midday when photosynthesis occurs at its maximum rate.

Question 25

What is an essential requirement for photosynthesis?

Answer 25

Water is an essential requirement for photosynthesis. It is absorbed from the soil by osmosis.

Question 26

Where is sugar produced on the Green Plants?

Answer 26

In green plants, sugars are produced in the leaves by photosynthesis.

Question 26

What are roots covered in?

Answer 26

Roots are covered in hundreds of microscopic projections called root hairs. These give the roots a greater surface area for absorption.

Question 27

Where does gas exchange occur?

Answer 27

Gas exchange occurs through the stomata, which are tiny pores on the underside of a leaf.

Question 28

What is an epidermal tissue?

Answer 28

Epidermal tissue is found covering the organs of plants. It has a protective role.

Question 29

What does photosynthesis produce?

Answer 29

Photosynthesis produces oxygen gas. This is removed from a plant's leaves during the day.

Question 30

What are plant organs specialised to do?

Answer 30

Leaves are plant organs specialised to absorb light for photosynthesis.

Question 30

What is Carbon dioxide?

Answer 30

Carbon dioxide is the gas that is removed from the air by green plants during photosynthesis.

Question 31

What is a stem?

Answer 31

The stem is a plant organ specialised to transport substances up and down a plant from the root to the leaves and leaves to roots.

Question 32

What can Stomatas do?

Answer 32

Stomata can open and close. The size of the pore is controlled by a pair of guard cells.

Question 33

What are Stomata?

Answer 33

Stomata are tiny pores on the surface of leaves. They allow the gas carbon dioxide, present in the atmosphere, to diffuse into the leaf.

Question 34

Where is the palisade mesophyll just above?

Answer 34

Epidermis

Question 35

What are roots covered in?

Answer 35

Root hair cells

Question 36

What do veins present in plants?

Answer 36

The veins present in plants are composed of xylem and phloem tissues.

Question 37

What happenes if a plant is stunned?

Answer 37

If the growth of a plant is stunted, it is deficient in nitrate ions.
