Plant tissues

PLANT TISSUES

DERMAL/PROTECTIVE (DÉRMICO)

• Protective tissue covers the surface of leaves and the living cells of roots and stems.

VASCULAR• Vascular tissue

transport nutrients, water, and sugars around the plant.

VASCULAR:XYLEM

• Xylem conducts water and dissolved minerals from the roots to all the other parts of the plant.

VASCULAR:PHLOEM

• Phloem transports the sugars and other molecules created by plant photosynthesis.

GROUND (FUNDAMENTAL)

• All tissues that are neither (no son) dermal nor (ni) vascular.

• It can be divided into three classes.

GROUNDPARENCHYMA

• Food storage

• Photosynthesis (with chloroplasts)

GROUNDSCLERENCHYMA

• Give mechanical support.

• Is found in stems and in leaf veins.

• Makes up the hard outer covering of seeds and nuts.

GROUNDCOLLENCHYMA

• They are in areas that are growing rapidly and need to be strengthened.
