Fragmentation: Asexual Reproduction in Plants

The video tutorial explores plant reproduction, focusing on asexual methods like fragmentation. Fragmentation allows plants to reproduce without gametes, creating genetically identical offspring. It occurs naturally in many plants and is used commercially for rapid propagation. While advantageous for quick reproduction, it lacks genetic diversity, posing risks during environmental changes.

What is a key difference between sexual and asexual reproduction in plants?

• Sexual reproduction does not involve flowers.

• Sexual reproduction results in genetically identical offspring.

• Asexual reproduction involves gametes.

• Asexual reproduction results in genetically identical offspring.

Which process is involved in the fragmentation of plants?

• Photosynthesis

• Meiosis

• Pollination

• Mitosis

How do strawberries naturally reproduce through fragmentation?

• By developing flowers

• By forming rhizomes or stolons

• By producing seeds

• By forming bulbs

What is a common method used by gardeners to propagate plants through fragmentation?

• Fertilization

• Layering

• Cross-pollination

• Seed planting

What is a disadvantage of asexual reproduction in agriculture?

• Increased genetic variation

• Higher energy requirement

• Lack of genetic variation

• Slower reproduction rate
