- 3. Features of organisms Learning Objectives: – Main features in the cells of living organisms. – Main features of the 5 kingdoms of living things. – The features used to place organisms into groups within the animal kingdom. – The main features used to place organisms into groups within the plant kingdom.
- 4. What are the main features in cells? All cell contains the following components (ORGANELLES): • Cell membrane – this is the outer surface of the cell and it controls what comes in and out of the cell. • Cytoplasm – a gel-like substance where most of the chemical reactions happen. • DNA – the genetic material that controls the cell’s activities.
- 5. What are the main features in cells?
- 6. What are the main features in cells? Also: • Ribosomes - they make proteins (PROTEIN SYNTHESIS).
- 7. ENZYMES: • An enzyme is a protein molecule. • The basic function of an enzyme is to increase the rate of a reaction. What are the main features in cells?
- 8. Kingdoms ●The first big division of living things in the classification system is to put them into one of five kingdoms. These are based on what an organism's cells are like. ●The five kingdoms are: ●Animals (all multicellular animals) ●Plants (all green plants) ●Fungi (moulds, mushrooms, yeast) ●Bacteria (all single cells) ●Protoctists (Amoeba, Chlorella and Plasmodium)
- 9. Animal Kingdom • They are MULTICELLULAR. • Cells contain a Nucleus. • They can MOVE AROUND.
- 10. Plant Kingdom • They are MULTICELLULAR. • Chloroplasts used for Photosynthesis. • Cell Wall made of cellulose that surrounds the cell membrane and provides support and strengthens the cell. • Vacuole a large space in the middle of the cell that contains salts and sugars to support the cell.
- 11. Prokaryote Kingdom • Bacteria. • They are Single Celled. • They don’t have a nucleus. Instead, they have a single strand of DNA in the cytoplasm. • They also contain Plasmids. (extra bits of DNA) • Most bacteria feed of other organisms (Living and Dead)
- 12. Fungi Kingdom • Can be single or multi-celled. • They contain hyphae (thread like structures that contain nuclei). • They can’t photosynthesise. • Their cell walls contain chitin. • They feed by saprotrophic nutrition which means they excrete enzymes around their body to dissolve food and then absorb the nutrients.
- 13. Protoctista Kingdom • They are single celled and microscopic. • Some have chloroplasts like plants. • Others are more like animal cells.
- 16. Viruses • They are smaller than bacteria. • They can only reproduce inside living cells. • They don’t have a cellular structure. • They have a protein coat around some DNA or RNA.
- 17. Coursebook Pgs 6-7 Title - The Kingdoms of living organisms. ● Write down the characteristics for each kingdom of living organisms. ● E.g: ● Animals – Multicellular – Cells have a nucleus, but no cell walls or chloroplasts – Feed on organic substances made by other living organisms.
- 19. Do you have a backbone? If an animal has a backbone it is called a vertebrate; if not, it’s called an invertebrate.
- 21. Worksheet 1.2 – Characteristics of vertebrates Complete the table for each specimen or picture: 1 2 3 4 1 5 6
- 22. Classification
- 23. Extension Pages 11 - 12 1) Write a list of the characteristics of Arthropods: ●Insects ●Crustaceans ●Arachnids ●Myriapods 2) Write a list of the characteristics of plants: ●Ferns ●Flowering Plants
- 24. Monocots and Dicots. (Plants) Monocotyledons: • One seed leaf. • Strap-shaped leaves. • Parallel veins. Dicotyledons: • Two seed leaves. • Various shaped leaves. • Branching veins.
- 27. Features of organisms Learning Objectives: – Main features in the cells of living organisms. – Main features of the 5 kingdoms of living things. – The features used to place organisms into groups within the animal kingdom. – The main features used to place organisms into groups within the plant kingdom.
Editor's Notes
- #23: Students don’t need to know the characteristics for each group
