Photosynthesis Flashcards
What is chloroplast
An organelle in plant that is a site for photosynthesis
What are thylakoids
Membranous sacs of chloroplasts that contain chlorophyll
Grana
Stacks of thylakoids were light phase of photosynthesis takes place
Stroma
Part of the chloroplast where dark phase occurs
Stomata
Pores on the leaves for gaseous exchange
Photolysis
Splitting of water molecules into oxygen and hydrogen
Phosphorylation
Formation of energy transport in molecules called app
Adenosine triphosphate
Energy carriers
List three factors that influence speed of photosynthesis
Light intensity. Concentration of carbon dioxide. Temperature.
Explain how light intensity influences the rate of photosynthesis
When light intensity increases the rate of photosynthesis also increases to an optimum level
How does the Constitution of carbon dioxide influence the rate of photosynthesis
Is carbon dioxide concentration level increases the rate of photosynthesis increases at an optimal level
How does temperature influence the rate of photosynthesis
What the temperature is lower the rate of photosynthesis as well as temperature increases the rate of photosynthesis increases
How do you investigate if light is required for photosynthesis
You firstly destarch the plants by placing it in a dark place for 48 hours and then you cover a portion of a leaf with aluminium and then you place to plant in a sunny area for 48 hours take the leave and remove the fuel and you test the presence of starch using starch test

How do you do a starch test
Firstly bitter leaf into boiling water for 30 seconds and then you remove the leaves from the water and place it in a tube for alcohol and then you put the tube back into the beaker of hot water and wondered if it was it will vary from the alcohol place it once again in the hot water for a few seconds and then you press delete on the spot in Thailand compared with iodine and leave it for a minute to the presents are both black colour indicates the presence of starch
