PROJECT: RESEARCH AND LEARN: PLANT REPRODUCTION Project Overview For this assignment, you will need to select two specific plants. One must reproduce sexually and the other asexually. Instructions You will describe the plant and the specifics of how they reproduce. Your description must include a step-by-step explanation. Your paper should be approximately 250 words in length.

Answer 1

Step 1: Pollination

In general, male gametes are contained in pollen, which is carried by wind, water, or wildlife (both insects and animals) to reach female gametes. The pollen is deposited on a plant's stigma, which is part of the pistil (the elongated part of a flower extending from the ovary). This process is called pollination.

Step 2: Germination

Within a few minutes, pollen tubes begin growing, or germinating, toward the egg cell. These tubes will provide a path for the sperm carried in the pollen to reach the egg.

Step 3: Penetration of the Ovule

The pollen tubes penetrate the ovule, which contains the female gametes.

Step 4: Fertilization

Sperm travel down the pollen tubes and fertilize an egg. Most angiosperms undergo double fertilization, where both an egg and the polar nuclei in the embryonic sac are fertilized.

Answer 2

Potatoes reproduce asexually by growing new plants from 'eyes' or buds present on their tubers. Roses, however, reproduce sexually, with pollen from the flower's anthers being transferred to the stigma, fertilizing the ovule which results in seed formation.

Step-by-step explanation:

Two examples of plants that reproduce differently are the Potato (asexual) and the Rose (sexual). Potatoes reproduce asexually through a method known as vegetative propagation. They grow tubers, which are swollen parts of the plant's underground stem, containing stored starch. New plants grow from the 'eyes' or the buds present on these tubers.

On the other hand, Roses reproduce sexually through the process of pollination and fertilization. Male pollen grains (from the flower's anthers) must be transferred to the female part of the flower (the stigma). This is often done by insects or wind. Once a pollen grain lands on the stigma, it grows a tube down to the ovule in the ovary and fertilizes it. This results in the making of seeds inside the rosehips.
