Plant tissues and specialized cells

• Dermal - Vascular - Ground

Epidermal tissue is a thin layer of cells that protect the leaves, stem, and flower. Root hair: extension of root epidermal tissue to increase the surface area for water and nutrient absorption. Epidermal tissues create a waxy cuticle on the leaves to protect the leaves from water loss

• Xylem - Phloem

The xylem transfers water and nutrients from the root to the leaves. A hollow tube connects the root and leaves.

Transfers sugars created by photosynthesis, other chemicals, and hormones throughout the body

It’s composed of all the tissue and is in between the vascular and dermal tissue In performs different functions in different parts of the plants - In roots - stores carbohydrates - in stem - it provides storage and support - In leaves- It preforms photosynthesis

• They have the ability to differentiate into any specialized cell • Only cell that will continue to divide throughout the life of the plant

• Apical meristem tissue is located at the tip of the root and shoot which allows the plant to grow longer (up and down) • Lateral meristem tissue is located in the stem and roots which allow the plant to grow wider (side - side)

• Create an opening in the cuticle which allows the gases (CO2) to enter the leaves during the process of photosynthesis. The openings are called stomata. Stomata are usually located on the underside of the leaves to reduce water loss during the evaporation and allow the upper surface to be used for photosynthesis.
