Germination of Seed Diagram

Seed Germination 

Seed germination is the process of growth and development of a seed into a New plant. This process starts when the seed takes up water. This activates the metabolic processes that allow the seed to grow roots, stem, and leaves. 

Seed germination  begins when the seed is exposed to favorable environmental conditions, such as favorable temperature, moisture, and light.The seed coat splits open and the embryo starts growing into shoot and root.Over the period of time the shoot will grow taller and the root will grow deeper into the soil, anchoring the plant and allowing it to access water and nutrients from the soil. Leaves will emerge from the shoot and the plant with the process of photosynthesis starts producing energy and eventually producing flowers and fruit.

Seed Germination Diagram

Seed Coat

Seed Coat is the protective layer around the embryo that helps to keep it safe and retain moisture until conditions are right for germination.

Embryo

Embryo is the young plant contained within the seed that will grow into a mature plant.

Cotyledon

Cotyledonis the first leaves of the embryo, often stored with food to support the plant’s growth.

Radicle

Radicle is the embryonic root that begins to grow downwards. It anchors the plant in the soil and absorbs water and nutrients.

Plumule

Plumule is the embryonic shoot that begins to grow upwards. It forms the stem and leaves of the Plant.

Hypocotyl

Hypocotyl is the part of the embryonic shoot that extends below the cotyledons. It  connects the root and shoot systems.

Epicotyl

Epicotyl is the part of the embryonic shoot that extends above the cotyledons. It  forms the stem and leaves of the mature plant.
