2. Define autotrophic      nutrition

4.What are the various steps of photosynthesis?
Answer: The steps of photosynthesis are-
* CO2 and H2O enter the         leaf 
*Light hits the pigment in the membrane of a thylakoid, splliting the H2O into O2
*The electrons move down to enzymes
*Sunlight hits the second pigment molecules allowing the enzymes ti convert ADP to ATP and NADP + gets converted to NADPH.
5. What are the different functions of stomata?
Answer:
*The gas exchange that occurs when stomata are open facilitates photosynthesis.During photosynthesis, carbon dioxide is taken in the from the atmosphere through stomata and oxygen is released as a waste product 
*Through the opening stomata the plants are able to minimize their the water through transpiration.
