Flashcards

Lateral Meristems

These are types of meristems that contribute to the growth in width of stems and roots. This is referred to as 'secondary growth'.

Primary Growth

The primary process of growth in plants that increases in length. It is associated with the growth of the shoot and the root.

Secondary Growth

The process of growth in plants that increases in width and girth. It is associated with the widening of stems and roots.

Apical Meristems

These are located at the tips of roots and shoots where cells divide and elongate, causing growth in length.

Permanent (Non-Meristematic) Tissues

These are specialized, differentiated cells that have stopped dividing and perform specific functions in a plant. Examples are vascular, ground, and dermal tissues.

Where are apical meristems located?

Apical meristems are present in both the shoot tips and root tips of plants. They are responsible for growth in length.
