Chapter 40.5, Problem 3LO
Summary Introduction
To describe: The three critical events that must accompany seed development.
Introduction: The plants are the multicellular eukaryotic organism in the kingdom Plantae. It is characterised by photosynthetic nutrition, a process through which it synthesis carbohydrates, essential unlimited growth at localised region, presence of cellulose in their cell wall and absence of locomotory organs.

- Suppose that 100 pollen grains land on a stigma, and 50 mature seeds are formed in the fruit. What does this indicate about the pollination process and success? A) 100% success: 100 pollen grains grew to 50 ovules, two to each, and double fertilization occurred. B) 100% success: Only 50% of the pollen grains germinated, but each produced 2 sperms to complete double fertilization in 50 seeds. C) 50% success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 50 polar nuclei. D) 50% success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 100 polar nuclei. correct answer and explanation why please.arrow_forwardDescribe three mechanisms whereby seed dormancy is broken in different types of seeds.

- 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.arrow_forward4. A) Identify which type of light (Red or Far-Red) simulates seed germination. B) Identify which type of light (Red or Far-Red) inhibits seed germination. C) If a group of seeds was exposed to the following light sequence: red → far-red →red → far-red → red → darkness, would seed germination be inhibited or simulated? Please answer in order and label them.arrow_forwardUsing the 'ABC model' of floral development, what would you expect the flowers of a mutant plant to look like if both A & B gene function had been destroyed?arrow_forward
