Tissue
a group of similar cells that are modified (or adapted) to carry out the same function
Tissue Culture
the growth of cells in or on a sterile nutrient artificial medium outside an organism
Organ
a structure composed of a number of tissues that work together to carry out one or more functions
Organ System
consists of a number of organs working together to carry out one or more functions
Basic Plant Tissues
dermal
vascular
ground
meristematic
Dermal Tissue
surrounds and protects the plant
e.g. epidermis
Vascular Tissue
transports materials throughout the plant
Types of Vascular Tissue
xylem and phloem
Xylem
transports water and dissolved minerals
Phloem
transports food
Basic Animal Tissues
epithelial
connective
muscular
nervous
Connective Tissue
consists of cells dispersed in a matrix, and it surrounds and supports body parts
Blood
a type of connective tissue that has red blood cells, white blood cells and platelets carried in plasma
Nervous Tissue
adapted to carry electrical impulses throughout the body
Neurons
nerve cells
In Vitro
means outside the body
Forms of Tissue Culture
micropropagation
monoclonal antibodies
growth of skin
Micropropagation
the growth of large numbers of plants from cells of a parent plant
rapidly produces new genetically identical plants
Monoclonal antibodies
combine with a specific, single type of antigen
may be used to attach to and show the presence of cancer cells
Growth of Skin
patient’s skin grown outside the body
new skin is grafted onto the wound
Plant Organs
include the root, stem, and leaf
Animal Organs
include the brain, liver, and heart
Animal Organ Systems
include the circulatory and the digestive systems
Organisation of Multicellular Living Things
cells → tissues → organs → organ systems → organism
