Reproduction and Domestication of Flowering Plants

These flashcards cover key terms and concepts related to the reproduction and domestication of flowering plants as outlined in the Campbell Biology lecture notes.

Angiosperms

Flowering plants that reproduce sexually and have seeds enclosed in a fruit.

Sporophyte

The diploid generation in the plant life cycle that produces spores by meiosis.

Gametophyte

The haploid generation in the plant life cycle that produces gametes.

Double fertilization

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

Ovule

The structure in seed plants that contains the female gametophyte and develops into a seed after fertilization.

Pollination

The transfer of pollen from the anther to the stigma.

Endosperm

A triploid tissue in seeds that provides nutrients to the developing embryo.

Fruit

Mature ovary of a flower that protects seeds and aids in their dispersal.

Apomixis

A form of asexual reproduction where seeds are produced without fertilization.

Self-incompatibility

Mechanisms that prevent self-fertilization in flowering plants, promoting genetic diversity.

Totipotency

The ability of a plant cell to differentiate into any cell type and develop into a whole organism.

Fragmentation

A method of asexual reproduction where a parent plant separates into fragments that develop into whole plants.

Vegetative propagation

A method of asexual reproduction induced by humans using plant fragments like cuttings.

Transgenic organisms

Genetically modified organisms that express genes from other species.

Coevolution

The process where two or more species influence each other's evolutionary path, often seen in flowers and their pollinators.

Meristematic tissue

Plant tissue that contains undifferentiated cells capable of division and can develop into different structures.
