Q

what is the recipe for photosynthesis?

A

Light (the sun), water (from the roots), carbon dioxide (from the air), Chlorophyll (from the cells of the green plants)

Q

What is photosynthesis?

A

The process by which glucose sugar and oxygen is produced. Photosynthesis occurs when a tree uses the sunlight and chlorophyll to convert carbon dioxide and water into glucose.

16
Q

what turns leaves green?

A

chlorophyll

17
Q

why do trees change color in fall?

A

because there is less sunlight and water for photosynthesis.

18
Q

True or False, a tree hibernates?

A

True, trees lose their leaves and store their food.

19
Q

what are the only living organisms that can make their own food?

A

Plants

20
Q

how do plants make their food?

A

by combining carbon dioxide gas in the air with water and nutrients that are absorbed in the soil using the energy they get from the sun- carbon dioxide and water react chemically to change into glucose and oxygen (photosynthesis)

21
Q

Write out the equation for photosynthesis

A

carbon dioxide (CO2) + water (H20) ==> sunlight ==> glucose + Oxygen

22
Q

where do plants store excesss glucose?

A

roots, stems and seeds of the plants

23
Q

True or false: the plants energy is transferred to the animals that eat them

A

true

24
Q

how do plants capture the suns energy?

A

because of chloroplasts on the leaves that contain chlorophyll. chlorophyll gives the leaves its green colour and is what is responsible for helping absorb solar energy

25
Q

True or False- Plants continue to make energy at night.

A

false - when there is no light, plants stop making energy,

26
Q

why are plants leaves broad and flat?

A

It is adapted to trap sunlight and carbon dioxide- a wide broad surface will capture far more light. (think solar panels)

27
Q

how do plants get their minerals?

A

through the soil using their roots.

28
Q

what will happen if the soil does not have enough nutrients?

A

the plant will not grow properly.

29
Q

what do farmers add to the soil if it does not have enough nutrients?

A

fertilizer

30
Q

why is photosynthesis one of the most important chemical reactions in the world?

A

1-it makes food for plants and animals and animals depend on them for food.
2-they breathe in carbon dioxide and release oxygen into the air for humans to breathe -otherwise we would suffocate
3- they remove carbon dioxide which is responsible for global warming

31
Q

what are the stages of the life cycle of mammals?

A

Birth, growth, reproduction and death

32
Q

what are the stages of the life cycle of living things that go through metamorphasis?

A

egg, larva, pupa (metamorphasis) and adult.

33
Q

chicken

A

egg stage, chick stage, pullet stage and adult stage
