Cytokinesis in Plant Cells • A plant cell has a rigid cell wall covering its cell membrane ( plasma membrane Instead, a forms between the two daughter nuclei • Cell walls form on either side of the cell plate creating Cytokinesis in Prokaryotic Cells Cell division is completed by a process called Mitosis When prokaryotic DNA is duplicated, both copies attach to the • As the cell membrane grows, the attached DNA molecules are centromere

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
