Pollination and Fertilization Vocabulary Flashcards

A set of vocabulary flashcards covering the definitions of pollination types, flower reproductive organs, and the basics of pollen grain structure based on the lecture material.

Pollination

The process of transfer of pollen grains from the anther to the stigma.

Anthers

Part of the stamens that produce a powdery material called pollen.

Pollen Grain

A particle containing two sperm nuclei that participate in reproduction.

Sperm Nuclei

Two reproductive components located within each pollen grain.

Autogamy

A type of pollination where the pollen of the same flower falls on its own stigma (self-marriage).

Geitonogamy

A type of pollination where the pollen of another flower of the same plant falls on the stigma (neighbouring).

Allogamy

The transfer of pollen from a flower of another plant of the same species to the stigma, also known as cross pollination.

Stamens

The male organs of a flower that produce pollen.

Agents of Pollination

Entities such as wind, insects, or water that facilitate the transfer of pollen grains.

Step 1 of Fruit/Seed Formation

The requirement that pollen grains must reach the stigma.
