Cell Diversity Flashcards
Tissue
A group of similar cells that are modified to carry out the same function
4 plant tissues are…
Dermal, vascular, ground, merimastic
Dermal tissue
Surround + protects the plant
Vascular tissue
Xylem transports water + dissolved minerals
Phloem transports food
4 animal tissues
Epithelial, connective, muscle and nervous
Connective tissue
Supports joints, valves, in skin, blood vessels and smooth muscle organs.
Adapted by increased synthesisation of matrix protein
Nervous tissue
Adapted to carry electrical impulses throughout the body
Nerve cells = neurons
Tissue culture
Growth of cells in/on a sterile nutrient artificial medium outside the body (in vitro)
Micropropagation
Growth of lots of plant cells of a parent plant
Rapid
Monoclonal antibodies
Combine with a specific type of antigen
Cancer research
Skin graft
Patient’s skin is grown in vitro + grafted onto wound
Circulatory system
Heart, blood vessels, lymph vessels, lymph.
Transports materials around the body + fights infection
Digestive system
Mouth, oesophagus, stomach, small intestine + anus
Takes in food, breaks it down, transfers the digested food into the circulatory system, so it can be carried to cells in the body.
