1.Parenchymatous Tissue
Parenchymatous cells form the bulk of the tissues of the root, stem cortex and leaf mesophyll layer. They are large, thin walled and generally undifferentiated.
Functions: healing, regeneration of damaged structures, photosynthesis, respiration, storage, secretion and movement of water and food.

Dermal tissue covers the outer surface of the root stem, leaves and fruits, protecting the inner cells from external hazards.
It consists of epidermis and periderm. It functions in the reduction of water loss in terrestrial plants during hot and dry periods.

3. Supportive Tissue
All higher land plants require support to help them withstand the effects of environmental conditions such as wind and rain.
Woody plants require a stronger system of support and have extensive supportive tissues known as collenchyma and sclerenchyma.

4. Vascular Tissue
All terrestrial plants need a vascular system to transport minerals and water to the leaves for photosynthesis, and then to distribute the products of photosynthesis through the plant.
Their vascular tissue is composed of xylem and phloem vessels.

Текст слайда:

Vascular Bundles: The vascular bundles form
the main transport system of higher plants
and consist of xylem and phloem vessels.
In dicotyledons that have no secondary
growth, the vascular bundles are initially
arranged in a circle around the outside of
the pith. The xylem and phloem vessels are
separated by a layer of meristematic tissue
known as cambium.
In monocotyledons, the xylem and phloem
are irregularly arranged in bundles through
out the ground tissue of the stem and there
is no cambium between them.

5.Secretory Tissue

Secretory cells may function either as a group or individually. Their by-products of
metabolism perform many useful roles. Resins and tanins are secretions that protect the plant from attack by pathogens.
Nectar provides an energy source for insects which in turn pollinate the female gametophyte.
Alkaloids are secretory poisons that defend the plant against herbivores.
