3) Size of organisms
4) Life span
5) Function
6) Reproduction
1) Number of cells = Single
2) Type of cells = Prokaryotic
3) Size of organisms = Microscopic
4) Life span = Short
5) Function = Cell has to carry out all functions
6) Reproduction = Asexual
Answer the following questions about Multicellular cells?
1) Number of cells
2) Type of cells
3) Size of organisms
4) Life span
5) Function
6) Reproduction
1) Number of cells = Multiple
2) Type of cells = Prokaryotic & Eukaryotic
3) Size of organisms = Macroscopic
4) Life span = Long
5) Function = Cell specialisation with hierarchical differentintation
6) Reproduction = Sexual, involving specialised sex cells
What are specialised cells?
Specialised cells are cells that are uniquely structured for a specific function.
What are the 4 main tissues found in animals?
1) Epithelial
2) Muscular
3) Nervous
4) Connective
What are the 4 main tissues found in plants?
1) Dermal
2) Ground
3) Vascular
4) Meristematic
What is the primary role of epithelial tissue? (animals)
Protection for exterior and interior lining of major organs and body cavities.
What is the primary role of muscular tissue? (animals)
Allows for movement of organs and body parts
What is the primary role of nervous tissue? (animals)
Communication
What is the primary role of connective tissue? (animals)
Provides structure and support to all parts of the body
What is the primary role of dermal tissue? (plants)
Skin layer of all plant organs. General function is protection
What is the primary role of ground tissue? (plants)
Storage, rigidity, and photosynthesis
What is the primary role of vascular tissue? (plants)
Transport of water and sugar. Also for support and rigidity
What is the primary role of meristematic tissue? (plants)
Groups of cells are able to divide and differentiate. Generally found at growth points.
