Plant Tissues
Plants have 4 different types of
tissues that help them survive.
Dermal Tissue
Ground Tissue
Meristematic
Tissue
Vascular Tissue
Dermal Tissue
Tissue that covers the plant.
Epidermis
Periderm - Cork/Bark
On non woody parts
On woody parts of the
plant
–Made of dead cells
Ground Tissue
Tissue that makes up the inside of plants.
It is specialized to:
Carry out
photosynthesis
in the leaves
Store
photosynthetic
products
Glucose
Support the plant
Vascular Tissue
Moves water, dissolved minerals and
nutrients throughout the plant body.
There are 2 types of vascular tissue:
Xylem
»Moves Water
Phloem
»Moves Nutrients
Vascular Tissue
Xylem
Moves water up
Phloem
Moves sugar and minerals
down.
Vascular Tissue
Xylem
Hollow, water-proof
tubes that allow water to
rise up in the plant via
capillary action
Phloem
Tubes that allow sugar
and minerals to move
down through the plant.
Xylem
Phloem
Mertistematic Tissue
Tissue that allows the plant to grow up,
down and/or out. Where mitosis occurs!
Plants have 2 types of meristematic tissue
Apical Meristem
–Allows growth at the tips of roots and
branches….up and down
Vascular Cambium
–In the outer layer of the stem/trunk that
allows outward growth (thickness)

Structures Overview
Plants have 3 main structures
1. Roots
 A system for absorbing dissolved minerals and
nutrients as well as water
2. Stems
 A structure used to support the body of the
plant
3. Leaves
The main photosynthetic regions of the plant.

Roots
• Help to anchor the plant to the ground
• Absorb water and dissolved nutrients/minerals
– Root hairs increase the surface area to increase
absorption
• Storage
– Sugars such as starch
• Propagation
