Lesson 2 Flashcards
State the purpose of photosynthesis in plants?
For plants to make there own energy
What does photosynthesis need?
Sunlight
Water
Carbon dioxide / C02
Chlorophyll
Nutrients
What does photosynthesis produces?
Oxygen
Sugar
What is photosynthesis essential for and where does it take place?
Photosynthesis is essential for growth and takes place in plants
What are green plants?
They are producers
What can producers survive without?
Without sugar
What do producers need?
Carbon dioxide and water
What can plants make that are complete?
Oxygen , starch, fat and proteins
What sugars can plants make?
Glucose
What chemical does sunlight get trapped into?
Chlorophyll
What does chlorophyll do in plants?
It makes the the plant green
When plants use carbon dioxide and water to make glucose there is a lot of _ _ _ _ _ left over
Sugar
Describe the function of the leafs organ?
It catches light for water to drop into the floor
Describe the function of the roots organs?
provides water and stores it and nutrients
Describe the function of the stems organs?
It holds up the plant and transfers water
In which part of a plant cell does photosynthesis take place?
Chloroplast
Which of the following is a specialisation which enables the roots of plants to efficiently?
A) a large surface are
B) a small surface area
C) many chloroplasts
D)thick cell walls
A large surface area
What does a waxy cuticle do?
It is waterproof and protects it like a barrirer
What do Guard cells do?
They open and close to let carbon dioxide in and oxygen out
What do Stomata do?
The stomata makes sure that there is enough water in the leaf
What do Air space do?
Air space lets gases flow
What do Spongy mesophyll do?
the exchange of gases essential to the process of photosynthesis
What do Palisade cells do?
The function of the palisade cell is photosynthesis. Each palisade cell contains chloroplasts which are used during this process.
