Plant Tissues: Meristems, Protective, and Supportive Tissues

Primary Meristem

Primary meristem is located at the tips of young plant organs: the apex of the root, stem, buds, etc., where it is the cone of plant growth. It provokes these organs to grow in length.

Root

Distinct parts are: suberized zone, absorbent hairs zone, and root cap zone. The growth zone is the subterminal region where the root meristematic tissue is located, causing an increase in the organ’s length. You can find 1, 2, or 3 meristematic cells. If there is 1 cell, this cell originates all

Plant Glands: Types and Secretions

Glands: External Secretion of Mucilage Cells: Cells with large nuclei, thick cell walls, numerous dictyosomes, and vesicles in the periphery. They contain mucilage and exhibit granulocrine secretion.

Glandular Salt Structures: Plants that live in saline soils, known as halophytes (e.g., Atriplex), have an epidermis covered with vesicular hairs that accumulate salts. In Caragana, salts are stored in vacuoles. When the cell collapses, the liquid content evaporates,
