- b) Presence of ovules.
- c) Presence of pollens.
- d) Heterospory.

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…arrow_forward
- 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_forwardWhere in an angiosperm would you finda megasporangium?(A) in the style of a flower(B) enclosed in the stigma of a flower(C) within an ovule contained within an ovaryof a flower(D) packed into pollen sacs within the anthers found on astamenarrow_forwardEndospermic seeds are found in: (a) castor (b) barley (c) coconut (d) all of thesearrow_forward
