| Who was Leeuwenhoek? | Leeuwenhoek was a famous microscope builder and was the first to discover unicellular organisms. |
| What did Robert Brown discover? | Robert Brown was behind the discovery of organelles, or more specifically the nucleus. |
| Who invented the first electron microscope? | Ernst Ruska |
| What are cells? | Cells are the small building blocks that make up all living things. |
| What was the cell theory? | 1. All living things are made ofcells. 2. Cells reproduce by dividing in 2. 3. Cells are the basic building blocks of all living things. |
| What are unicellular organisms? | Unicellular organisms are organisms made up of only one cell. |
| What are organelles? | Organelles are even smaller particles (structures) within the cell that act like small organs. |
| Name 5 organelles found in animal cells. | 1. Nucleus 2. Mitochondria 3. Lysosomes 4. Ribosomes 5. Endoplasmic Reticulum |
| What is mitochondria? | The powerhouses of the cell that release energy from food. |
| What is a nucleus? | The nucleus is the main organelle which has control over all movements of the cell. |
| What are ribosomes? | Ribosomes are microscopic 'factories' that produce proteins used for the growth and repair of the cell. |
| What are lysosomes? | Lysosomes are the garbage disposal units that get rid of waste from the cell. |
| What are endoplasmic reticulum? | Endoplasmic reticulum form pathways that allow materials to move easily through the cell. |
| What is a cell membrane? | The cell membrane is the 'skin' that holds the cell together. |
| What is a vacuole? | A vacuole holds water and chemicals that are carried around the cell. |
| What is a cytoplasm? | The water and jelly-like mixture that makes up the cell and holds smaller organelles in it. |
| What are chloroplasts? | Chloroplasts are organelles holding chlorophyll used in the process of photosynthesis. |
| What is a cell wall? | The cell wall is the skeleton-like outside of a cell. |
| Which organelles/parts of a cell are only found in plant cells and not animal cells? | Chloroplasts and the cell wall. |
| Describe the steps of photosynthesis. | 1. Plant takes in carbon dioxide 2. Uses sunlight, water, carbon dioxide and chlorophyll to make its food. 3. Produces oxygen and glucose. |
| In which way is a fungal cell similar to a animal cell? | A fungal cell has a similar inner structure to an animal cell. |
| In which way is a fungal cell similar to a plant cell? | A fungal cell has a cell wall like a plant cell (however made of different chemicals). |
| Name a unicellular fungal cell? | Yeast |
| How do cells reproduce? | Cells reproduce through a process called mitosis where the cell divides into two identical cells. |
| Who was the first to discover cells and how? | Robert Hooke, when he looked through a microscope at a thin slice of cork and saw small bumps representing cells. |
| Who invented the first microscope? | Zacharias Janssen. |
