This new yeast cell develops, matures, and multiplies to make additional yeast cells. A high number of yeast cells get generated in a short period of time. 2. Zygote: Seeds in embryonic plants are encased in a protective coating. After being fertilized by pollen and growing within the mother plant, a matured ovule produces seeds. The embryo is created from the zygote, while the seed coat is formed from the ovule’s integuments.
