life cycle

Question 1

what does the life cycle show?

Answer 1

A life cycle shows how living things grow and change over time

Question 2

how do most plant life cycles start?

Answer 2

seed

Question 3

what are two ways an animal can be born

Answer 3

egg or live birth

Question 4

which of these animals goes through metamorphasis during its life cycle? Penguin, chicken, gorilla, frog

Answer 4

frog

Question 5

At what stage of a life cycle is the butterfly able to fly? Egg, Larva, Pupa, Adult?

Answer 5

Adult

Question 6

How is a chicken born?

Answer 6

Mating and an egg

Question 7

Do frogs start their life cycles on land or water?

Answer 7

water

Question 8

stages of a frogs life cycle in order?

Answer 8

egg –> tadpole –> tadpole with legs and arms –> frog

Question 9

Describe the metamorphasis a butterfly goes through over its lifetime.

Answer 9

egg—> caterpillar –>Chrystal stage –> butterfly

Question 10

what type of food does a tree use to grow and what is it called?

Answer 10

Glucose - a type of sugar.

Question 11

how do trees absorb water and minerals?

Answer 11

Through their roots

Question 12

How do trees make glucose?

Answer 12

leaves.

Question 13

How does the tree “eat”?

Answer 13

It sends glucose from the leaves to the other parts of the tree (trunk, branches, roots)

Question 14

what is the recipe for photosynthesis?

Answer 14

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

Question 15

What is photosynthesis?

Answer 15

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.

Question 16

what turns leaves green?

Answer 16

chlorophyll

Question 17

why do trees change color in fall?

Answer 17

because there is less sunlight and water for photosynthesis.

Question 18

True or False, a tree hibernates?

Answer 18

True, trees lose their leaves and store their food.

Question 19

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

Answer 19

Plants

Question 20

how do plants make their food?

Answer 20

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)

Question 21

Write out the equation for photosynthesis

Answer 21

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

Question 22

where do plants store excesss glucose?

Answer 22

roots, stems and seeds of the plants

Question 23

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

Answer 23

true

Question 24

how do plants capture the suns energy?

Answer 24

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

Question 25

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

Answer 25

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

Question 26

why are plants leaves broad and flat?

Answer 26

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

Question 27

how do plants get their minerals?

Answer 27

through the soil using their roots.

Question 28

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

Answer 28

the plant will not grow properly.

Question 29

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

Answer 29

fertilizer

Question 30

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

Answer 30

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

Question 31

what are the stages of the life cycle of mammals?

Answer 31

Birth, growth, reproduction and death

Question 32

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

Answer 32

egg, larva, pupa (metamorphasis) and adult.

Question 33

chicken

Answer 33

egg stage, chick stage, pullet stage and adult stage
