1. 3.1.3 Ultrastructure of a Cell L.O: To label the organelles found in a eukaryotic cell To describe the function of each organelle Starter: Spot the Difference! In pairs, look for the differences between the two cells below:

2. Prokaryotic v.s. Eukaryotic Cell ‘Before nucleus’ ‘after/good nucleus’ ProkaryoticEukaryotic Types of organisms Bacteria, algaeAnimals, plants, fungi NucleusNo distinct nucleusNucleus surrounded by nuclear membrane Cell Wall Always have a cell wall Only in plants and fungi OrganellesVery fewMany

4. Cell Structure Poster Collect a piece of coloured paper and 7 different coloured pens Draw a circle taking up nearly all of the page

5. Nucleus: contains chromatin, the condensed form of chromosomes. Nuclear pores allow substances to move in and out. Nucleolus makes ribosomes.

6. Ribosomes: either found in cytoplasm or attached to rough E.R. These are the site of protein synthesis.

7. Nucleus: contains chromatin, the condensed form of chromosomes. Nuclear pores allow substances to move in and out. Nucleolus makes ribosomes. Ribosomes: either found in cytoplasm or attached to rough E.R. These are the site of protein synthesis. Endoplasmic Reticulum: (2 types) Rough E.R. has ribosomes attached and provides large surface area for making proteins. Smooth E.R. Creates and stores lipids and carbohydrates.

8. Golgi Apparatus: Processes and modifies proteins and lipids made by the E.R. These are packaged into vesicles and move out of the cell. Also makes lysosomes.

9. Lysosomes: vesicles containing enzymes

10. Golgi Apparatus: Processes and modifies proteins and lipids made by the E.R. These are packaged into vesicles and move out of the cell. Also makes lysosomes. Lysosomes: vesicles containing enzymes Mitochondria: site of aerobic respiration. Double membrane folded into cristae to increase surface area, inner matrix contains enzymes for respiration.

11. Golgi Apparatus: Processes and modifies proteins and lipids. These are packaged into vesicles and move out of the cell. Also makes lysosomes. Lysosomes: vesicles containing enzymes Mitochondria: site of aerobic respiration. Double membrane folded into cristae to increase surface area, inner matrix contains enzymes for respiration. Plasma membrane: made of lipids and carbohydrates, it regulates the movement of substances in and out of the cell.

12. Specialised Cells Extension: Think of examples of cells with lots of: a)Mitochondria b)Endoplasmic reticulum c)Lysosomes

13. Bingo! Draw a 3 x 3 grid and write in 9 of the following words: Lysosome, vesicle, prokaryotic, eukaryotic, endoplasmic reticulum, mitochondria, pores, golgi apparatus, ribosomes, chromatin, plasma membrane, cristae, enzymes, matrix, nucleolus.
