What Are the Common Forms of Plant Reproduction?
Plant fertilization or reproduction is the union of male and female reproductive cells to produce a fertilized egg (zygote). Reproduction in plants is a petty straight forward process that is similar for flowering plants and seed-bearing plants. Here is a breakdown of four generalized steps. Step 1: Pollination - Normally, pollen contains male gametes. The pollen deposits on a plant's stigma that becomes part of the pistil. This process is called pollination. Step 2: Germination - Within just a few minutes, the pollen tubes start growing toward the egg cell. The tubes provide a path for the sperm carried in the pollen to reach the egg. Step 3: Penetration of the Ovule - Pollen tubes penetrate the ovule that contains the female gametes. Step 4: Fertilization - Sperm travels down the pollen tubes and fertilize the egg. Most angiosperms experience double fertilization, where both an egg and the polar nuclei in the embryonic sac is fertilized.
