Chapter 40.4, Problem 1CS
Summary Introduction
To describe: The model of seed germination by a flow diagram.
Introduction: The fusion of male and female gametes results in the process of fertilization. The process of embryogenesis takes place after the fertilization of gametes. After a certain period of time, the embryo gets covered by a seed coat and the formation of seed takes place. The ovules, after fertilization, result in the formation of seeds.

INSTRUCTIONS: ESSAY (Write in your own words no longer than 350 words)
Seed germination may depend on the presence or absence of several external and internal factors. Discuss one external and one internal factor that may influence the successful germination of seeds.

1. An aggregate fruit develops from the fused ovaries of a floral cluster.
2. In the fern leaf, the clusters of sporangia are called sporophylls.
3. The plumule is the first seed leaf that absorbs and digests nutrients needed for seed germination.
4. A false fruit develops from the expansion of the hypanthium or floral tube that encloses the ovary.
5. The endocarp is the edible fleshy part of the fruit.
6. In a bean seed, the part of the embryo which develops into the leaves and upper portion of the stem is known as the hypocotyl.
7. The embryos of corn and other grass seeds are partially enclosed in a protective sheath called the coleorhiza.
8. The embryonic shoot system is the radicle.
9. The seed coat develops from the nucellus of the ovule.
10. In the Zea mays seed, the aleurone layer is located outside the endosperm layer.

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.

Drain off excess alcohol from the buds and aseptically excise the anthers from each bud. Remove the filaments and culture the anther on one of the agar media provided. Label the stage of development of the bud on each petri dish as the anthers are cultured. Seal the Petri dishes with parafilm. Incubate in the dark at 26 to 28ºC for 4 to 8 weeks or until small plants can be seen growing out of the anthers. Then transfer to diffuse light.

It is important that you read each question completely before you begin. An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, Seedings were germinated on moist paper towels at 20°C for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures.
