- B. Which region of the embryo elongates during epigeal germination to bring the shoot above ground? C. Which regions of the embryo stay below ground following epigeal germination?Given below is an experimental setup to demonstrate a particular tropic movement in germinating seeds. Study the diagram and answer the questions that follow Perforated trough Moist sawdust - Germinating seed -Brick (i) Label the parts 1 and 2. (ii) Name the tropic movement shown by part 1. (iii) Part 1 is affected by two stimuli. Name them. Which one of the two is stronger? (iv) What is Thigmotropism ? Give one example. (v) What is meant by 'Positive' and 'Negative' tropic movements in plants?In a common eudicot pattern of development for the common bean in the figure, the radicle emerges from the seed (1), then begins to develop into a primary root that grows down into the soil. As this occurs, the hypocotyl emerges from the seed and bends into the shape of a hook (2). The bent hypocotyl lengthens and pulls the cotyledons upward (3). When the hypocotyl reaches the soil surface, exposure to light causes it to straighten (4). Primary leaves emerge from between the cotyledons and begin photosynthesis. The cotyledons typically undergo a period of photosynthesis before shriveling (5). Eventually, the cotyledons fall off the lengthening stem, and the young plant’s new leaves produce all of its food. a) Identify and explain what environmental factors influence the timing and coordination of the germination of seeds.
