An important gene involved in the phototropism in plants is: TIN PIN TDN PDN2. A cell organelle in plants which sediment at the lowest part of the cells and initiate differential growth patterns and bending the root towards the vertical axis is: Statoliths Lithocytes Gravicytes Graviplasts3. Prolamellar bodies are present in: Chloroplasts Leucoplasts Etioplasts Chromoplasts4. The hydrostatic opening of stomata is due to Movement of water into guard cells Low water potential in mesophyll cells Decreased concentration of ABA Movement of K+ ions into guard cells5. Phototropins are a class of photoreceptor proteins that mediate phototropism responses in higher plants are: Channel proteins Flavoproteins Membrane proteins Metalloproteins6. Bending of coleoptiles tip of oat towards the source of unilateral light of wavelength 454 nm is due to Polar transport of auxin Degradation of auxin in the light area Lateral distribution of auxin toward shaded area Synthesis of auxin in the shaded area7. Statocytes are: Starch storing cells in multicellular algae Light perception cells in plants Star-shaped cells in some sponges Gravity perception cells in plants8. Statoliths are: Protein-filled organelles in aleurone layer of seeds Starch-filled amyloplastic organelles in root Protein-filed organelles in the embryo-sac Starch-filled pyrenoid analogues in higher plants9.
