1. Why are plants green? Explain
Ans: Plants are green because their cells contain chloroplasts which have the pigment chlorophyll which absorbs deep-blue and red light, so that the rest of the sunlight spectrum is being reflected, causing the plant to lookgreen.
2. What are the end products of photosynthesis.
Ans: The end product of photosynthesis is a glucose and oxygen molecule. This chemical reaction is best described by the formula CO2+H2O+energy -> sugar + O2.
3. What are the organisms capable of photosynthesis
Ans: Organisms such as plants, algae and some bacteria are capable of carrying out photosynthesis.
4.What are the major photosynthetic pigments in plants.?
Ans:Major photosynthetic pigments include:
5. What is photorespiration and in which type of plants it occurs?
Ans:Photorespiration is a metabolic pathway that occurs in plants in the presence of light, in which ribulose bisphosphate carboxylase/oxygenase (rubisco), the enzyme involved in carbon dioxide fixation with ribulose bisphosphate, accepts oxygen, in place of carbon dioxide, resulting in the formation of a two-carbon compound, glycolate.Generally photorespiration occurs in C3 plants
6. What does stroma refer to?
Ans: In chloroplasts , stroma is large space enclosed by inner membrane and filled with granular fluid/matrix
7.What does the term grana refer to?
Ans: Grana is the stacks of thylakoids embedded in the stroma of a chloroplast.
8.What structure/organelle is required by an organism to be classified as a autotroph.
Ans. Chloroplasts
