Provide a brief discussion on the development of the parts of the mature corn seed and monggo seed
Step by step
Solved in 2 steps
- What is the water content of matured seed and what is the reason behind for the low water content? *Identify the origin of each of the three parts of a seed.Describe three mechanisms whereby seed dormancy is broken in different types of seeds. How are these mechanisms related to the typical environment of the plant?
- State the structures/features observed in early and late stages of eudicot seed development.Describe the structure of a seed. Include the following: Seed coat, endosperm and embryo.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.
- Give an overview of the theory of Germination and types of germinationDescribe advantages and disadvantages of producing a crop of potato plants using asexual (tuber) rather than sexual (true seed) propagation.The three main parts of a typical mature eudicot seed are the _______ . a. pollen grain, egg, and seed coat b. embryo, endosperm, and seed coat c. megaspores, microspores, and ovule d. embryo, cotyledons, and seed coat
