Photosynthesis Flashcards
What is Photosynthesis
-The process by which plants produce food
What are the requirements for photosynthesis
- light energy
- Carbon dioxide
- Water
- Chlorophyll
What plants contain chlorophyll?
Only green plants
What do plants produce as a result of photosynthesis?
- Glucose (Sugar)
- Oxygen ( release in atmosphere
Chemical reaction for photosynthesis is?
Page 15 - for formula
When plants absorb carbon dioxide and release oxygen is called ?
Gaseous exchange
What is parasites
- Live on living organic tissue
- obtain all nutrients from the host
What happens with the host
It is harmed in the relationship
Examples of parasites plants are
- Dobber
- mistletoe
What is a saprophytes
-Survive on dead organic tissue
Examples of saprophytes
- sugarcane
- Indian pipe
- certain orchids
What is gaseous exchange?
its the absorption and immune of gases
Where does gaseous exchange take place?
Through the stomata which is found mainly in the leaves of plants
Where does the gaseous exchange happen
- through the stomata
- are found mainly in the leaves
Can stomata also be found in parts of the plant
yes
What so plants use to respire
-glucose
The energy that is released during respiration is used for the following life process:
- propagation
- cell division
- growth
- other life processes
Some glucose can be converted into
cellulose which forms cell walls
What is glucose
starch
What are green plants
autotrophs
What does autothropic mean
have the ability to produce their own food
What is the comparison between photosynthesis and respiration
P - Only takes place in plants
R - Takes place in plants and animals
P - Oxygen and sugar are formed during the process
R - Water and carbon dioxide are formed during this process
P - Photosynthesis needs sunlight
R - Respiration does not need light
P - Food is produced
R - Food is broken down
P - Energy is stored
R - Energy is released
P - Only takes place in cell that contain chlorophyll
R - Takes place in all living cells
P - An anabolic (constructive) metabolic process
R - A catabolic (destructive) metabolic process
