Conifers are classified as gymnosperms because they bare cones for reproduction and not flowers. 2. In a conifer, where does the union of the egg and sperm occur? How does sperm reach the egg? The sperm does not have the motility required to move to the egg, so the sperm must rely on the wind to carry it to the egg. The sperm are carried by pollen tube to the egg in the ovule.

3. Describe the structure and shape of the conifer needle. What is the role of the conifer needle? How does its structure help conserve water? The needle is a thin sticky leaf. The role of the needle is to photosynthesize and absorb/transport water. The needles are able to retain more water because there is the waxy surface on it that will hold the water in rather than let it out. 4. What purpose do the root hairs serve? What purpose does the tap root serve? The root hairs are used to absorb nutrients from the soil and to then transport it throughout the plant. The tap root is mainly used to anchor and help stabilize the plant. 5. What is the function of the seed coat? What is the benefit of the stored carbohydrates in the seed? The seed coat’s function is to protect the seed before and during germination. The carbohydrates are used to help the seed survive by using these stored sugars until it is able to produce/absorb its own. 6. What generation, sporophyte or gametophyte, does the embryo of a seed represent?

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
