Chapter 8: Cell Diversity

tissue

A group of similar cells that are adapted to carry out the same function

4 plant tissue types

dermal, ground, vascular, meristematic

dermal tissue function

Surrounds and protects the plant, e.g. epidermis

vascular tissue function

transports materials throughout the plant, e.g. xylem and phloem

xylem

transports water and dissolved minerals

phloem

transports food

4 basic animal tissue types

epithelial, connective, muscular, nervous

connective tissue adaptation

collagen fibres in tendons and ligaments are strong and resist stretching

nervous tissue adaptation

carries electrical impulses throughout the body

tissue culture

The growth of cells in or on a sterile nutrient medium outside the body

in vitro

outside the body

an organ

several tissues working together to carry out one or more functions

A organ system

group of organs that work together to carry out one or more functions

Micropropagation

A method of cloning large numbers of plants using explants and tissue culture
