Questions and Answers
A gardener wants to clone a plant with desirable traits quickly. Which method of reproduction would be most effective?
A gardener wants to clone a plant with desirable traits quickly. Which method of reproduction would be most effective?
- Sexual reproduction through cross-pollination to ensure genetic diversity.
- Grafting the plant onto a different rootstock to combine traits.
- Vegetative propagation using cuttings from the parent plant. (correct)
- Planting seeds collected from the plant to produce offspring.
A potato farmer notices that some potatoes in storage have started to sprout from their 'eyes.' What type of reproduction is occurring?
A potato farmer notices that some potatoes in storage have started to sprout from their 'eyes.' What type of reproduction is occurring?
- Vegetative propagation from the buds. (correct)
- Sexual reproduction through seed formation.
- Asexual reproduction through budding
- Spore formation leading to new plants.
How does vegetative propagation impact the genetic diversity of plants in a cultivated field?
How does vegetative propagation impact the genetic diversity of plants in a cultivated field?
- It maintains genetic uniformity, as offspring are clones of the parent plant. (correct)
- It has no impact on genetic diversity as it only affects physical traits.
- It leads to gradual genetic drift due to environmental factors.
- It increases genetic diversity by introducing new gene combinations.

Flashcards
Vegetative Propagation
Vegetative Propagation
A form of asexual reproduction in plants where a part of the plant grows into a new, genetically identical plant.
Budding
Budding
A form of vegetative propagation where a small outgrowth develops on a yeast cell, eventually forming a new individual.
Potato Eyes
Potato Eyes
Small buds on potatoes that can sprout into new leafy branches, demonstrating asexual reproduction.

Study Notes
- Vegetative propagation is a plant's method of asexual replication, where a portion of the plant grows into a new one.
- A stem or leaf piece placed in water can form roots and mature into an adult plant, a genetic duplicate of its parent.
- Potato "eyes" are buds that sprout new leafy branches, demonstrating asexual reproduction.
- Planting these sprouting sections leads to mature potato plants.
Budding
- A bud is a small, bulb-like projection from a yeast cell.
- The bud grows and detaches from the parent cell, creating a new yeast cell.
- The new yeast cell matures and multiplies.
- A chain of buds can form when another bud grows from the original one.
- Repeating this process can produce many yeast cells.
