Exp:C Plastids of an etiolated plant possess chlorophylloid and carotenoids. Etiolation of a plant is the elongation and weakening of the plant stem and development of yellowish white color in its leaves. - Phycobilins : Phycobilins are water soluble pigments that are fairly joined to a protein - Carotenoids: The carotenoids are an important group of pigments in plants where they function as accessory light- harvesting pigments in photosynthesis. - Xanthophyll : They are photochemical cooling agents that deal with the active state of chlorophyll or triplet chlorophyll.

Which of the following organelles contain circular DNA?
1 Peroxisomes and Mitochondria
2 Mitochondria and Golgi complex
3 Chloroplasts and Lysosomes
4 Mitochndria and Chloroplast
Explanation:
Exp:D Mitochondria and Chloroplast organelles contain circular DNA. Mitochondria and chloroplast have endo-symbiotic origin prokaryotic type. So have ds circular DNA as that of prokaryotes. Peroxisomes - Peroxisomes are abundant in the liver where they produce bile salts, cholesterol and break down fats.

In chloroplasts, chlorophyll is present in the
1 outer membrane
2 inner membrane
3 thylakoids
4 stroma
Explanation:
Exp:C The thylakoids are flattened sacs that are filled with a fluid called the stroma. The chlorophyll molecules are embedded in the thylakoid membrane. Stroma - It provides nutrients to the tissue or organ and removes waste and extra fluid. Dark reaction of photosynthesis occurs in stroma of chloroplast.

Which of the following is responsible for red colour of tomato?
1 Chlorophyll
2 Phycoerythrin
3 Phycocyanin
4 Lycopene
Explanation:
Exp:D Most tomatoes are red when they are ripe because of the presence of lycopene, which is a phytochemical (A biologically active compound produced by plant. Lycopene is organic compound of \(\beta\)-carotene. It is a natural pigments that gives some vegitables and fruits their red colour. Lycopene in tomato products could have protective effects against prostate cancer and cardiovascular disease. Phycocyanin \(\rightarrow\) It is an accessory pigments of chlorophyll. They are water soluble so, they cannot exist within the membrane. Phycoerythrin \(\rightarrow\) It is widely used as a fluorescent probe or as a colorant industries for labeling antibodies.
