what does the life cycle show?
A life cycle shows how living things grow and change over time
how do most plant life cycles start?
seed
what are two ways an animal can be born
egg or live birth
which of these animals goes through metamorphasis during its life cycle? Penguin, chicken, gorilla, frog
frog
At what stage of a life cycle is the butterfly able to fly? Egg, Larva, Pupa, Adult?
Adult
How is a chicken born?
Mating and an egg
Do frogs start their life cycles on land or water?
water
stages of a frogs life cycle in order?
egg –> tadpole –> tadpole with legs and arms –> frog
Describe the metamorphasis a butterfly goes through over its lifetime.
egg—> caterpillar –>Chrystal stage –> butterfly
what type of food does a tree use to grow and what is it called?
Glucose - a type of sugar.
how do trees absorb water and minerals?
Through their roots
How do trees make glucose?
leaves.
How does the tree “eat”?
It sends glucose from the leaves to the other parts of the tree (trunk, branches, roots)
what is the recipe for photosynthesis?
Light (the sun), water (from the roots), carbon dioxide (from the air), Chlorophyll (from the cells of the green plants)
What is photosynthesis?
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.
what turns leaves green?
chlorophyll
why do trees change color in fall?
because there is less sunlight and water for photosynthesis.
True or False, a tree hibernates?
True, trees lose their leaves and store their food.
what are the only living organisms that can make their own food?
Plants
how do plants make their food?
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)
Write out the equation for photosynthesis
carbon dioxide (CO2) + water (H20) ==> sunlight ==> glucose + Oxygen
where do plants store excesss glucose?
roots, stems and seeds of the plants
True or false: the plants energy is transferred to the animals that eat them
true
how do plants capture the suns energy?
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
