Plant Structure Flashcards
What is the formula for photosynthesis
Carbon dioxide+water–>glucose+oxygen
What part of the cell does photosynthesis contain
Chloroplasts
What do the chloroplasts
Chlorophyll
What does the sunlight do in photosynthesis
Converts the carbon dioxide into glucose
What is the top and bottom layer of the leaf called
Epidermis
What is the middle of the leaf called
Mesophyll
Where are the chloroplast situated in the leaf
Just under the epidermis
How does Carbon dioxide get into the leaf
Through the stomata
What are the three limiting factors of photosynthesis
Light intensity
Carbon dioxide
Temperature
Why does a plant have an optimum temperature
Because the enzymes need to work at a certain temperature
What is glucose used for in plants
Respiration Making cell walls Making proteins Stored as starch Stored as lipids
What happens with the energy created by respiration in a plant
Coverts the glucose into other substances and to grow
How are cell walls made by glucose
Glucose is converted into cellulose
What is glucose combined with to make a amino acids
Nitrate ions
Why is starch a good way of storing energy
It is insoluable
What is the purpose of the epidermis and how is it adapted to this purpose
Allow light to reach the palisade cells
By being thin an transparent
What is the task of the palisade cell
To absorb light and is adapted to do so by being near the top of the tissue and by containing many chloroplasts
What is the purpose of the spongy mesophyll
To allow the carbon dioxide to diffuse through the leaf and increase its surface area
In lab conditions what is used to to increase levels of carbon dioxide
Sodium hydrocarbnate is added which can dissolve in water
