Reproductive Systems in Plants

These flashcards cover key concepts related to sexual and asexual reproduction in plants, methods of reproduction, types of flowers, and related processes.

Sexual Reproduction

A reproductive process that involves the fusion of male and female gametes to form a zygote.

Asexual Reproduction

A reproductive process that does not involve the fusion of gametes and results in offspring that are genetically identical to the parent.

Artificial Vegetative Reproduction

A method of plant propagation involving human intervention, such as cutting, grafting, or layering.

Pollination

The transfer of pollen from male anthers to female stigma in flowers, crucial for fertilization.

Types of Flowers

Flowers can be categorized as complete (having all floral parts) or incomplete (lacking one or more parts) and perfect (having both male and female structures) or imperfect (having only one sexual part).

Advantages of Sexual Reproduction

Promotes genetic variation, which can enhance adaptability and evolution in changing environments.

Disadvantages of Sexual Reproduction

Requires more time and energy, often needing pollinators and can lead to less reliable reproduction success.

Advantages of Asexual Reproduction

Quick and efficient, produces identical offspring, and can propagate successful traits in stable environments.

Disadvantages of Asexual Reproduction

Lacks genetic diversity, making populations vulnerable to diseases and environmental changes.

Fertilization

The process where the male gamete (sperm) unites with the female gamete (egg) to form a zygote, leading to seed development.
