Biology: Germination and Plant Structures

These flashcards cover key vocabulary and concepts related to germination and plant structures based on the lecture notes.

Germination

The process by which a seed develops into a self-supporting plant when certain conditions are met.

Cotyledons

Seed leaves that store food for the young plant and protect the plumule during germination.

Radicle

The part of the seed that will develop into the root of the plant.

Plumule

The part of the seed that will develop into the shoot of the plant.

Testa

The outer coat of the seed that protects it from fungi, bacteria, and insects.

Photosynthesis

The process by which green plants make their own food using sunlight, carbon dioxide, and water.

Conditions for germination

Water, oxygen, and the correct temperature are required for seed germination.

Micropyle

A small hole in the testa that allows water to enter the seed.

Hilum

A scar left by the stalk that attached the seed to the fruit.

Asexual Reproduction

A method by which some plants create new plants from structures other than seeds, such as buds or bulbs.

Monocotyledon

A type of flowering plant that has one seed leaf.

Dicotyledon
