Differentiate asexual and sexual reproduction in plants

Site author Richard Steane. The BioTopics website gives access to interactive resource material, developed to support the learning and teaching of Biology at a variety of levels. Humans, Plants Variation, Ecology. This unit has recently been expanded - 2 Differentiate asexual and sexual reproduction in plants at the end. Before a cell divides, its nucleus divides. Each chromosome is copied, and each nucleus receives the same genetic material: As each cell divides into two, the resulting "daughter" cells are therefore exact copies of one another.

This process is responsible for the increase in number of cells which occurs during normal growth and developmentand when tissues are replaced following injury.

Normal cell division is also the basis for asexual reproduction. Only one type of cell is involved, with no input from another individual.

Because no new genetic material is introduced, there is no variation in the resulting offspring. Since the offspring from this process contain the same genetic material as one another and the same as the original single parentthey can be described as a clone.

Many plants used for food can be propagatedi. Fruits and seeds are produced as a result of sexual reproduction. Each of the examples of food plants below uses asexual and sexual reproduction in different ways.

More about strawberries More about bananas More about potatoes More about onions More about apples. Bacteria reproduce asexually by a simpler process known as binary fission.

Asexual reproduction is much less common in animals, but it is often seen in simpler animals e. Another related topic on this website: Both male and female sex cells sperms and eggs in animals, pollen and ovules in plants are produced by a special cell division process which halves the number of chromosomes in each resulting cell.

The chromosome separation process ensures that each sex cell has a unique combination of genes in its nucleus.
