Photosynthesis(ecosystems) Flashcards
(21 cards)
Plants are essential to the survival of life on our planet.This is because they:(2)
- )remove carbon dioxide
2. )release oxygen into the atmosphere
How do plants make their food.
Plants make their own food, using carbon dioxide (from the air) and water (from the soil)
What are the 2 materials needed for plants to make food.
The 2 raw materials used for plants to make food:
- )Carbon dioxide
- )Water
What is the name of the process where plants make food?
This is called photosynthesis.
Word equation for photosynthesis…
Carbon dioxide +water -(light) glucose+ oxygen
What were the Reactants and Products of photosynthesis ?
Reactants=carbon dioxide and water
Products=Glucose and oxygen
What makes plants green?
Chlorophyll 🌱
Where does photosynthesis take place in the plant?
In the leaves 🍃
What do plants need for photosynthesis and where does it come from?
Plants need energy for photosynthesis , this energy comes from the sun.
What is glucose?
A sugar that is made during photosynthesis
What happens to glucose?
It is quickly turned into insoluble starch to be stored
What happens to starch?
The starch can be broken down into glucose .
Where does starch go?
Starch is carried around the plant to the places where they are needed.
What is a biomass?
The total quantity or weight of organisms in a given area or volume.
What do some farmers use? And why?
A greenhouse, to control he environment.
Explain 3 things about chloroplasts and chlorophyll…
Chloroplasts have bubbles or chlorophyll.
Chlorophyll is a green pigmented chemical, it can absorb sunlight (it makes plants green).
What do all living things need?
Energy
What are plants are called?
Producers
What is the name of the waste gas is produced during photosynthesis?
Oxygen
How can the rate of photosynthesis be measured?
Because oxygen waste product was released from plants while photosynthesising,count the rate of bubbles from pondweed.
What happens as the light source moves further away from the pond weed?
The number of bubbles per min decrease as the light source moves further away.This is because plants needed light to photosynthesise.
