Circadian rhythms in plants are chiefly regulated by______. Phototropins and Phycobilins Phycobilins and Phytochromes Phytochromes Phototropins2. Statocytes are: Starch storing cells in multicellular algae Light perception cells in plants Star-shaped cells in some sponges Gravity perception cells in plants3. The hydrostatic opening of stomata is due to Decreased concentration of ABA Low water potential in mesophyll cells Movement of K+ ions into guard cells Movement of water into guard cells4. Cryptochromes are a class of flavoproteins of plants involved in circadian rhythms are: Sensitive to blue light Sensitive to red light Sensitive of UV light Sensitive to green light5. Statoliths are: Starch-filled pyrenoid analogues in higher plants Starch-filled amyloplastic organelles in root Protein-filed organelles in the embryo-sac Protein-filled organelles in aleurone layer of seeds6. Non-directional movements of plant parts in responses to stimuli are called: Tactic movements Nastic movements Tropic movements7. Prolamellar bodies are present in: Chloroplasts Leucoplasts Chromoplasts Etioplasts8.
