  1. Asexual Reproduction Question and Answer Ms. Cyr

  2. What is Asexual Reproduction? • Asexual reproduction is the formation of a new individual that is genetically identical to the parent. (A clone) • Some advantages of asexual reproduction are: only needing one parent to reproduce), and numerous offspring can be produced with little effort. • To be classified as a eukaryote, a cell must have a nucleus. • A prokaryote cell has no nucleus, and only a single chromosome.

  3. Asexual Reproduction in Bacteria • Binary fission is when a parent divides so that both new cells contain a single chromosome. • An advantage to having such a short cell cycle is rapid population growth. (Not always good for us!!)

  4. Asexual Reproduction in Protists • Protists are different from bacteria because they have a true nucleus. • Mitotic cell division in amoebas results in offspring that are genetically identical.

  5. Asexual Reproduction in Fungi • Three types of organisms that are classified as fungi are: moulds, yeast and mushrooms. • Hyphae grow over the surface of an organism and into the bodies of other organisms to obtain food. • Three methods of asexual reproduction in fungi are: • Fragmentation: a fragment breaks away and grows into a new individual. • Budding: a copy of the nucleus is made; the new nucleus moves into a tiny bud that forms in the cell wall. The bud grows and eventually separates. • Spores: contains all genetic information. Leaves the sporangium and can start a new colony.

  6. Asexual Reproduction in Fungi Continued • A sporangium provides a place for spores to develop. • Spores travel by air currents. • Apply your knowledge: Covering food in the fridge helps keep spores out so mould will not spread!

  7. Asexual Reproduction in Animals • Animals can be divided into vertebrates (have a backbone: human, dogs, reptiles) and invertebrates (no backbone: sponge, jellyfish) • A planarian, if cut into two pieces, will grow into 2 new worms. This happens because of regeneration. • Other animals that can reproduce asexually are sponges and hydra.

  8. Asexual Reproduction in Plants • The meristem of a plant is where cells that undergo mitosis rapidly are located. • Meristematic cells repair damaged cells and are the site for asexual reproduction. • Dandelions are difficult to get ride of because when you pull them out, there is often a piece of root left behind that can grow into a new plant.

  9. Asexual Reproduction in Plants • Layering is when a branch or limb from the parent plant is buried, and a new plant grows from that spot. (Strawberries) • Grafting is when stems are grafted (attached) to roots of another plant, and start to grow.
