Photosynthesiz Flashcards
Plants use sunlight energy to make
Their own food.
Plants are _________hs
Autotrophs.
Photosynthesis is the process in which
Hint
Photosynthesis is _______
In which glucose and oxygen is made by plants from carbon dioxide and water.
Light from sun is NEEDED
As a source of energy.
Chlorophyll is NEEDED
As a catalyst for the process
Photosynthesis is represented by the balanced equations :
CARBON DIOXIDE
6CO2
Photosynthesis is represented by the balanced equations :
WATER
6H20
Photosynthesis is represented by the balanced equations :
SUGAR
C6 H12 O6
C 6 • H 12 • O 6
Photosynthesis is represented by the balanced equations :
OXYGEN
6O2
The source of raw materials for photosynthesis:
CARBON DIOXIDE enters
Through the STOMATA
The source of raw materials for photosynthesis :
WATER comes up VIA
To the leaf from the roots VIA the xylem vessels in the vein.
Photosynthesis requires Chlorophyll because
Photosynthesis requires the presence of a green pigment in the plant cell.
What is Chloroplast found where?
It is a pigment found in a cellular organelle.
FOUR THINGS PHOTOSYNTHESIS requires :
Water
Carbon Dioxide
Light Energy
Chlorophyll
THE THREE ROLES OF PHOTOSYNTHESIS
- Plants use it to make food.
- Animals get their food from plants.
- Produces o2 that living things need to obtain energy.
6CO2 is …
6H2O is….
C6 H12 O6 is….
6O2 is …..
Carbon dioxide
Water
Sugar/Glucose
Oxygen
The main EVENTS in Photosynthesis.
STEP ONE
Light energy is absorbed by chlorophyll.
The main EVENTS in Photosynthesis.
STEP TWO
Water is split using sunlight energy.
The main EVENTS in Photosynthesis.
STEP THREE
Sunlight energy trapped by chlorophyll is passed onto electrons inside that from
HIGH ENERGY ELECTRONS.
The main EVENTS in Photosynthesis.
STEP FOUR
HIGH ENERGY ELECTRONS stored protons and CO2 MAKE GLUCOSE.
Photosynthesis in Farming.
Plants produce…
Plants produce cereals fruits and vegetables which are needed to make food for cattle.
Photosynthesis & Agriculture & Plant Yields.
What is a plant yield?
A plant yield means how much food a plant will produce for a grower.
Photosynthesis & Agriculture & Plant Yields.
Greenhouses raise what to increase what
Green houses raise temperatures to increase rate of photosynthesis.
Photosynthesis & Agriculture & Plant Yields.
Carbon Dioxide added to what to increase what
Carbon dioxide can be added to greenhouses to INCREASE crop yields.
Photosynthesis & Agriculture & Plant Yields.
Artificial Light used in what areas to increase what during what
Artificial Light can be used in shaded areas to increase photosynthesis even during night.
