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
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.
________is the emergence of the embryo from a seed. Usually, the_______ (structure of the embryo) emerges first. In monocots, the shoot is protected by a sheath called the_______ . In dicots, a(n)______in the hypocotyl or epicotyl protects the apical meristem and developing leaves.
You want to examine the internal anatomy of seeds from Taxus and Ricinus. The plant material you obtain only consists of mature seeds - this can be challenging as mature seeds are often quite hard making it difficult to cut a longitudinal slice through the seeds from each genus. In addition to your drawings, you described (with great accuracy) what you saw as follows: A. The coyledons of the Ricinus embryo were just about visible, though often hard to distinguish, surrounded by the nutritive endosperm tissue. The seeds of Taxus were too mature to slice open but they were surrounded by the fleshy, red tissue that contains the poisonous substance taxol. B. The coyledons of the Ricinus embryo were just about visible, though often hard to distinguish, surrounded by the nutritive endosperm tissue. The seeds of Taxus were too mature to slice open but they were surrounded by the fleshy, red tissue that birds eat. C. The coyledons of the Ricinus embryo were just about…
In most parts of the world, commercial potato crops are producedasexually by planting tubers. However, in some regions, such asSoutheast Asia and the Andes, some potatoes are grown from trueseeds. Discuss the advantages and disadvantages of growingpotatoes from true seeds.
How would plant development change if the functions of the genes SHOOTMERISTEMLESS (STM) and MONOPTEROUS (MP) were reversed? a. The embryo–suspensor axis would be reversed. b. The embryo–suspensor axis would be duplicated. c. The root–shoot axis would be reversed. d. The root–shoot axis would be duplicated.

Imagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree? Please be detailed as possible
Why is it that even if you put the newly germinated seed in an inverse position (roots above), the roots will find its way back to the ground?
