Flashcards
What is asexual reproduction?
What is asexual reproduction?
Asexual reproduction involves only one parent plant and does not require fertilization, resulting in offspring identical to the parent. Examples are vegetative propagation (stem cuttings), budding (yeast), fragmentation (Spirogyra), and spore formation (fungi and ferns).
What is sexual reproduction?
What is sexual reproduction?
Sexual reproduction needs two parents, usually with separate male and female reproductive organs. It involves fertilization of gametes (sperm and egg) to form a zygote, leading to offspring with diverse genetic makeup. This is typical of higher plants.
What is vegetative propagation?
What is vegetative propagation?
Vegetative propagation involves using parts of a plant (stem, root, leaf) to grow a new individual. This is a type of asexual reproduction, producing offspring genetically identical to the parent.

Study Notes
Asexual Reproduction
- Asexual reproduction involves only one parent
- Offspring are genetically identical to the parent
- Occurs in lower plants
- Reproductive organs are not present
- Processes like gamete formation or fertilization are not seen
- No need for seeds
Sexual Reproduction
- Involves two parents (male and female)
- Offspring are genetically different from the parents
- Occurs in higher plants
- Reproductive parts are present
- Involves gametes (male and female) forming a zygote
- Seeds are used to develop new plants from a flower
Methods of Asexual Reproduction
- Vegetative propagation: New plants are produced from stems, leaves, or roots (e.g., rose, sugarcane, sweet potato, carrot)
- Budding: New organisms develop from the parent body as a bulb-like projection (e.g., yeast)
- Fragmentation: New organisms are formed from fragments of the parent body (e.g., spirogyra)
Spore Formation
- Many non-flowering plants (fungi and ferns) reproduce through spores
- Spores are found within the plant body
