PLANT TISSUES EASY to UNDERSTAND (copy)

Plant Tissues

Differentiated groups of cells that perform specific functions in a plant.

Meristematic Tissue

Temporary plant tissue where growth occurs, can differentiate into various types of tissues.

Permanent Tissue

Long-lasting plant tissue derived from meristematic tissue, includes parenchyma, collenchyma, and sclerenchyma.

Vascular Tissues

Xylem and phloem responsible for transporting water, minerals, and nutrients throughout the plant.

Apical Meristems

Found at the tips of shoots or roots, responsible for primary growth and lengthening of the plant.

Lateral Meristems

Found in the stem, responsible for secondary growth and thickening of the plant.

Cambium

Ring of tissue in the stem that allows for lateral growth, responsible for increasing stem width and bark formation.

Epidermis

Outermost layer of permanent tissue in plants, provides protection and helps in preventing water loss.

Mesophyll

Tissue located beneath the epidermis where photosynthesis occurs.

Epidermis Tissue

The outermost layer of cells covering the plant body, specialized to allow sunlight penetration and protect the plant.

Guard Cell

Cells surrounding the stomata that control the opening and closing of the stoma as well as substances that leave and enter the stomata through the vacuole.

Root Hair Cell

Specialized cells on the surface of roots, elongated to increase surface area for nutrient absorption.

Parenchyma

Parenchyma cells have thin cell walls with intercellular spaces for, gas exchange, osmosis and the parenchyma stores food and water, if it has chloroplasts it is called the Chlorenchyma.

Collenchyma

The corners of collenchyma are unevenly thickened which cellulose and it does not have intercellular spaces . Collenchyma provides support and strength to parts of the plant whilst still being flexible

Xylem

A type of vascular tissue in plants responsible for transporting water and minerals from the roots to the shoots.

Sclerenchyma

A type of ground tissue in plants that provides rigidity and strength, found in roots, stems, and branches, and is divided into fibers and sclereids and it is dead.

Sclereids

Another type of sclerenchyma found in nuts or stone fruits, contributing to the hard shell or pit.

Vessels

Elongated and round structures in xylem responsible for transporting water and minerals.
