PARTS OF A SEEDLING

PARTS OF A SEEDLING

A young seedling consists of three main parts:

1.   Radicle (embryonic root),

2.   Hypocotyl (embryonic shoot), and

3.  Cotyledons (seed leaves).

4.  Epicotyl (Plumule).

 

RADICLE:

It is the first part of a seedling to emerge from the seed during the  process of germination.

The radicle is the embryonic root of the plant, and grows downward in the soil. 

 

 

COTYLEDONS:

Cotyledons are the seed leaves which provide food to the seed.

HYPOCOTYL:

Above the radicle is the embryonic stem or hypocotyl, which is the connection between the cotyledon and the radicle.

 

EPICOTYL/PLUMULE:

The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. 

Plumule grows after the growth of radicle. It is the embryonic shoot.
