1. Fundamentals of Biology

2. The ingredients of life Beside water, carbon, hydrogen and oxygen are necessary for life. Beside water, carbon, hydrogen and oxygen are necessary for life. Compounds made up of these three things are known as organic compounds Compounds made up of these three things are known as organic compounds

3. The four main groups of organic molecules Carbohydrates Carbohydrates Proteins Proteins Lipids Lipids Nucleic acids Nucleic acids

4. Carbohydrates Starches and sugars Starches and sugars Functions - used for energy & structure -chitin (shells of marine organisms) and cellulose (the main ingredient of wood and plant fibers) Functions - used for energy & structure -chitin (shells of marine organisms) and cellulose (the main ingredient of wood and plant fibers)

5. Proteins Functions: make up muscles, enzymes, hormones, carry oxygen, and even act as antifreeze in Antarctic fishes Functions: make up muscles, enzymes, hormones, carry oxygen, and even act as antifreeze in Antarctic fishes

6. Lipids Fats, oils and waxes Fats, oils and waxes Functions: energy storage, waterproofing, insulation and help with buoyancy Functions: energy storage, waterproofing, insulation and help with buoyancy

7. Nucleic Acids Functions: store and transmit the basic genetic information of all living things Functions: store and transmit the basic genetic information of all living things

8. Cells Prokaryotes vs Eukaryotes Prokaryotes vs Eukaryotes Prokaryotes – no organelles Prokaryotes – no organelles Eukaryotes – organelles Eukaryotes – organelles

9. Life in the sea What is unique about living in the ocean? What is unique about living in the ocean? Salt water Salt water

10. Dealing with the salt Diffusion – molecules moving from high concentration to low. Diffusion – molecules moving from high concentration to low. Cells spend most of their energy actively transporting materials opposite the direction of diffusion. Cells spend most of their energy actively transporting materials opposite the direction of diffusion.

11. Marine fish have the ability to rid their body of excess salt – through their gills and in their urine Marine fish have the ability to rid their body of excess salt – through their gills and in their urine

12. Reproducing Sexual – eggs, sperm and fertilization – offspring inherits genes from each parent Sexual – eggs, sperm and fertilization – offspring inherits genes from each parent Asexual – budding, and fission – all offspring are exact copies of parent Asexual – budding, and fission – all offspring are exact copies of parent

13. Why the diversity? Theory of evolution – the gradual alteration of a species genetic make-up. Theory of evolution – the gradual alteration of a species genetic make-up. Why does this occur? Why does this occur? Natural Selection – the best adapted individuals produce more offspring Natural Selection – the best adapted individuals produce more offspring
