, Grade 10 Life Sciences Notes Plant Tissues
WHAT IS A TISSUE
A tissue is a group of cells, not necessarily identical, but from the same origin, that together carry out
a specific function. These are called tissues because of they are functioning together.
TISSUE STRUCTURE FUNCTION
Thin-walled, immature cells that Make new cells for growth
divide often •Some new cells stay
•Cells tightly packed in layers or rows meristematic
•No intercellular spaces •Some cells differentiate and
•Single large nucleus become permanent tissues
•Dense cytoplasm
•Small or no vacuole
MESISTEMATIC TISSUE
Single layer of tightly packed, thin Forms an outer cover and protect
walled cells plant
•Cover the plant •Controls movement of water out of
•Aerial parts covered with a waxy layer plant
cuticle • Roots absorb water
•Cuticle protects plant
•Cuticle prevents too much water loss
•Often adapted for extra functions,
e.g. Root hairs increase surface area
to absorb water
EPIDERMAL TISSUE
