D3.1 Germination (SL)

Flashcards covering key terms and definitions related to plant systems and germination.

Germination

The process by which a seed emerges from dormancy and begins to sprout.

Sexual reproduction

A reproductive process involving the fusion of male and female gametes, resulting in genetically diverse offspring.

Self-pollination

A reproductive mechanism where pollen from the same flower fertilizes its ovules, leading to inbreeding.

Cross-pollination

The transfer of pollen between different plants leading to genetic diversity.

Pollination

The transfer of male pollen grains to a female stigma.

Fertilization

The fusion of haploid gametes, leading to the formation of a zygote and eventually a seed.

Self-incompatibility

Mechanisms in plants that prevent self-fertilization and promote genetic variation.

Epicotyl

The embryonic shoot of a seed.

Radicle

The embryonic root of a seed.

Cotyledon

The part of a seed that acts as a food storage for the developing plant.

Testa

The outer seed coat that protects the seed.
