Homework Answers
Answer-
Endosperm is a tissue present inside the seeds of most angiosperms. It is generally triploid (3n) which is a result of fertilization of two polar nuclei of cells of embroyonic sac by one sperm nucleus. It acts as food storage for the seed during germination. Developing embryo gets nutrients from endosperm. It helps in transfer of nutrients from mother plant to the embryo. It also contains hormone such as cytokinin which regulate cellular differentiation and embryonic organ formation. In some cases, endosperm also helps in seed dormancy which helps annual plants encounter the effects of year-to year variation in the environment.

Question 24 3 pts The seeds of orchids (an angiosperm) are among the smallest known, with virtually no endosperm. What is therefore likely to be true? There is no fruit surrounding the seed. O Double fertilization does not occur in this species. Orchids are not true flowering plants. The developing plant quickly obtains nutrition through photosynthesis or other means. o Orchid pollen grains are unusually large.

Need help with reviewing my lab report -- Question on Germinating Seeds Plants and plants have been studied for hundreds of years, dating back to the geological era of the Holocene, which began around 11,700 years ago. How to study its effects was by noting the effects of the plants on humans, i.e. herbal medicine, which is the doctrine of how to use herbs in various ways to promote health. Fast-forward to 1665 and using an early microscope to detect...

The seeds in bush bean pods are each the product of an independent fertilization event. Green seed color is dominant to white seed color in bush beans. If a heterozygous plant with green seeds self-fertilizes, what is the probability that 6 seeds in a single pod of the progeny plant will consist of ... A. 1 green and 5 white seeds? Express your answer to three decimal places (example: 0.123). B. All green seeds? C. At least one white seed?

Practice questions.. 12. A population of plants produces seeds which are eaten by ants. The ants select for the seeds which are the largest they can carry (about medium-sized) to maximize the food content. They eat these seeds, and thus destroy them. In the coming generations, what do you think will happen to the seed size in this population? A. The medium sized seeds will become more common B. The largest and smallest seeds will become more common C. Seed...

A variety of pure-breeding snapdragons produces a tall plant with green seeds (WWSS). A second variety of pure-breeding snapdragons produce a short plant with white seeds (wwss). The two varieties are crossed, and the resulting seeds are collected. All of the seeds are green and when planted, they produce all tall plants (WwSs). These tall F1 plants are allowed to self-fertilize. The results for seeds and plant height in the F2 generations are as follows. What is the Х 2...
