Study Notes
Asexual Reproduction
Binary Fission
- A type of asexual reproduction where a single cell divides into two identical daughter cells
- Occurs in bacteria, protozoa, and some algae
- Process:
- Cell growth and replication of genetic material
- Cell division into two identical daughter cells
- Each daughter cell receives a complete set of genetic material
Budding
- A type of asexual reproduction where a new individual grows from a bud on the parent organism
- Occurs in yeast, hydra, and some corals
- Process:
- Formation of a bud on the parent organism
- Growth and differentiation of the bud into a new individual
- Separation of the new individual from the parent
Fragmentation
- A type of asexual reproduction where an organism breaks into fragments, each of which grows into a new individual
- Occurs in some invertebrates, such as starfish and worms
- Process:
- Breaking of the parent organism into fragments
- Regeneration of missing body parts in each fragment
- Growth of each fragment into a new individual
Spore Formation
- A type of asexual reproduction where an organism produces spores, which can grow into new individuals
- Occurs in fungi, plants, and some bacteria
- Process:
- Production of spores by the parent organism
- Dispersal of spores into the environment
- Germination of spores into new individuals
Vegetative Propagation
- A type of asexual reproduction where a new plant grows from a vegetative part of the parent plant
- Occurs in plants, such as potatoes, garlic, and strawberries
- Process:
- Formation of a vegetative part, such as a tuber or runner
- Growth of a new plant from the vegetative part
- Separation of the new plant from the parent plant
Asexual Reproduction
Binary Fission
- A single cell divides into two identical daughter cells, occurring in bacteria, protozoa, and some algae
- Cell growth and replication of genetic material precede cell division
- Each daughter cell receives a complete set of genetic material
Budding
- A new individual grows from a bud on the parent organism, occurring in yeast, hydra, and some corals
- Formation of a bud on the parent organism precedes growth and differentiation into a new individual
- The new individual separates from the parent after growth and differentiation
Fragmentation
- An organism breaks into fragments, each of which grows into a new individual, occurring in some invertebrates, such as starfish and worms
- Breaking of the parent organism into fragments is followed by regeneration of missing body parts
- Each fragment grows into a new individual after regeneration
Spore Formation
- An organism produces spores, which can grow into new individuals, occurring in fungi, plants, and some bacteria
- Spores are produced by the parent organism and dispersed into the environment
- Germination of spores into new individuals occurs after dispersal
Vegetative Propagation
- A new plant grows from a vegetative part of the parent plant, occurring in plants, such as potatoes, garlic, and strawberries
- Formation of a vegetative part, such as a tuber or runner, precedes growth of a new plant
- The new plant separates from the parent plant after growth from the vegetative part
