Plant Reproduction Flashcards

Flashcards covering vegetative propagation, sexual reproduction, and artificial propagation methods.

What is vegetative propagation?

Asexual reproduction in plants

Give examples of plants that propagate via stems.

Strawberries (runners)

What plant uses a swollen underground root for vegetative propagation?

Dahlia tubers

How do leaves contribute to vegetative propagation?

Leaves of some plants will form a new plant if detached (e.g., Mother of Thousands)

What are bulbs considered in terms of plant structure?

Modified buds (e.g., onions)

List a key difference between sexual and asexual reproduction regarding genetic variation.

Asexual reproduction produces genetically identical offspring (clones), while sexual reproduction produces genetically different offspring.

List a key difference between sexual and asexual reproduction regarding the number of parents.

Asexual reproduction requires one parent, while sexual reproduction requires two parents.

Name three methods of artificial vegetative propagation.

Layering, grafting, cuttings, and micropropagation

Describe the process of layering in artificial vegetative propagation.

The growth of a new plant from a stem that is still attached to the parent plant.

Describe the process of grafting in artificial vegetative propagation.

The joining of part of one plant with a second plant

What is micropropagation?

The growth of plants from small pieces of tissue under sterile conditions on an artificial medium

What is one advantage of sexual reproduction compared to vegetative propagation?

Variation and more disease resistant offspring

What is one disadvantage of sexual reproduction compared to vegetative propagation?

Slower process

What is one advantage of vegetative propagation compared to sexual reproduction?

No variation (preserves desirable features and fast)

What is one disadvantage of vegetative propagation compared to sexual reproduction?

More prone to disease
