- 2What does the Nucleus do?Controls all activities of the cell
- 3What is Cell Membrane?The skin that holds the cell together. It controls what comes in and out of the cell
- 4What does Vacuole do in animal cells?May contain wastes or chemicals that are being moved around the cell
- 5Define RibosomesMicroscopic 'factories' that produce proteins used by the animal for growth and repair. They aren't considered true organelles because they aren't always enclosed in a membrane
- 6What additional structures do plant cells have that animal cells don't?Cell wall, Chloroplast and a larger Vacuole
- 7Is the Vacuole in a plant cell or animal cell larger?Plant cell
- 8Define ChloroplastsContain a green substance called chlorophyll and are found in the green parts of plants. Photosynthesis also takes place here
- 9What process do plants use to make food?Photosynthesis
- 10Define PhotosynthesisA process where plants use energy from the Sun to chemically combine water and Carbon Dioxide from the air to make a sugar called glucose
- 11Describe the Vacuole of a plant cellIt's large and occupies most of the cell. It's filled with sap and stores water, wastes and nutrients
- 12What lies outside the cell membrane and keeps the plant upright?Cell wall
- 13Define FungiFungi (Fungus) are organisms that can be made of just a single cell or many cells
- 14How does Fungi get food?They produce and release chemicals that digest the material they are growing on. They then absorb the digested material into their cells
- 15What type of cell has the same organelles as an animal cell but with a cell wall?Fungi Cell
- 16What are the building blocks of all living things?Cells
- 17What are organelles?Other structures within a cell
- 18What is a living thing that is only made up of one cell known as?Unicellular organism
- 19Define BacteriaSmall & simple cells that do not have any organelles or a true nucleus
- 20What is the name of the group that Unicellualr organisms belong to?Protists
- 21What is Mitosis?When a cell divides into two identical cells. First the nucleus divides into two and then the cytoplasm divides
