Asexual Reproduction
Fichas del conjunto (30)
- 1What is asexual reproduction?The production of new organisms involving only one parent or parent cell
- 2In asexual reproduction the offspring develop from ___ cellsundifferentiated
- 3What type of cell division is involved in asexual reproduction?Mitosis or Mitotic cell division
- 4What are the 6 types of cell division?Binary Fission, Budding, Spore formation, Regeneration, vegetative propagation and Tissue culture
- 5State 3 ways in which asexual reproduction is differs from sexual reproduction?1. Asexual Reproduction involves one parent/parent cell while sexual reproduction involves 2 parents or parent cells
2. Asexual reproduction offspring are genetically identical to parents (no variation) while sexual reproduction offspring are not identical to parents (variation)
3. Asexual reproduction occurs rapidly while sexual reproduction occurs at a slower rate - 6What is the simplest form of Asexual Reproduction?Binary Fission
- 7What does the terms Binary and Fission represent in Binary fission?Binary - Two
Fission- dividing or splitting - 8Which organisms use Binary Fission?Single celled organisms including Bacteria and protists such as amoeba
- 9What occurs during Binary Fission? (Short answer)The parent organism divides into two approximately equal parts
- 10What occurs during Binary Fission in the form of Amoeba? (Detailed answer)When a cell is ready to produce, genetic material replicate, then the nucleus then divides followed by the rest of the cell.
- 11What occurs during Binary Fission in the form of Bacteria? (Detailed answer)Bacteria lack an organized nucleus so the hereditary material is in the form of a single circular chromosome. (Bacteria can split once every 20 mins.)
- 12What is another name for 'Spore formation'?Sporulation
- 13What are spores?Small, often microscopic, specialized cells. Note: Each spore contains a nucleus and a small amount of cytoplasm surrounded by a thick, hard outer wall. The protective wall enables spores to survive unfavorable environmental conditions such as extreme cold, heat, or dryness, for long periods of time.
- 14What organisms use Sporulation/ Spore Formation?Bacteria, yeasts, molds, mushrooms, mosses, and ferns
- 15List the 3 types of hyphae that make up bread mold:Rhizoids, Stolons, and Sporangiophores
- 16What are Rhizoids?Root like hyphae that penetrate bread; anchors fungus to bread; releases digestive enzymes and absorbs nutrients
- 17What are Stolons?stem like hypahe that run along the surface of bread
- 18What are Sporangiophores?Stem like hyphae that form sporangia (spore containing structure at the top); supports Sporangium
- 19What is the Sporangium?Spore case
- 20What is a network of hyphae called?Mycelium
Note: It is through the Mycelium that that a fungus absorbs nutrients from the environment - 21What is budding?New organisms are formed as small out growths or buds on the outer surface of the parent organism.
Note: The buds may break off and live independently or remain attached (forming a colony) - 22How does budding differ from binary fission?Budding differs from Binary fission because the parent and offspring aren't the same size
- 23What is regeneration?The ability of an organism to regrow lost body parts.
- 24Examples of organisms that use regeneration?Hydra, Planaria, Starfish, and Earthworms
- 25What happens when a hydra is cut in half?Each half will regenerate into a new individual
- 26Vegetative Propagation: What are vegetative structures?Roots, Stems, and Leaves.
- 27What happens during vegetative reproduction?undifferentiated cells divide mitotically and then differentiate to give rise to a new independent plant
- 28Vegetative reproduction occurs ____ and artificiallynaturally
- 29List the 4 types of natural vegetative reproductionBulbs, Tubers, Runner (Stolon), and Rhizomes
- 30What are the 4 types of Artificial Reproduction?Cuttings, Layering, Grafting, and Marcotting
