Ch. 38 - Plant Reproduction

This set of flashcards covers key concepts regarding angiosperm reproduction and biotechnology, as outlined in the lecture notes.

Mutualistic symbioses

Interactions between angiosperms and other species where plants lure insects with nectar.

Angiosperms

A group of plants that reproduce sexually and asexually, and are the most important in terrestrial ecosystems and agriculture.

Double fertilization

A unique process in angiosperms where one sperm fertilizes the egg, and the other combines with polar nuclei to form endosperm.

Sporophyte

The dominant generation in angiosperms; a diploid plant that undergoes meiosis to produce spores.

Gametophytes

Haploid structures in angiosperms that are produced by the sporophyte and give rise to gametes through mitosis.

Inflorescences

Clusters of flowers that can vary in structure and function in angiosperms.

Pollination

The transfer of pollen from an anther to a stigma, facilitated by wind, water, or animals.

Coevolution

The evolution of interacting species in response to changes in each other, such as between flowering plants and their specific pollinators.

Seed dormancy

A state in which seeds remain inactive until favorable conditions for germination arise.

Asexual reproduction

A process resulting in genetically identical organisms, often through fragmentation or adventitious shoots.

Sexual reproduction

A reproductive process resulting in genetically distinct offspring, promoting genetic variation and evolutionary adaptation.

Self-incompatibility

Mechanisms that prevent self-fertilization in angiosperms, ensuring genetic diversity.
