Life and Living Things

1. Life and Living Things Cells

2. What are the structures of a cell? Compare and contrast plant and animal cells. Name the functions Of each structure in the cell.

3. Complete the web with four characteristics of cells. All organisms -living things- are made of cells. Cells do the jobs that keep organisms alive. Cells Cells are the smallest part of a living thing. These cells are like tiny building blocks.

4. What is the smallest part of this living thing? Cells !

5. BrainPOPCell Structures • What are some parts of cells? What do the parts do? How are cells different from one another? How do cells make more cells? What other questions do you have about cells? Scroll down and click on cell structures.

6. PARTS of a CELL • Cell membrane – the outside of a cell; it controls what comes in and out of a cell. • Cytoplasm – The gel-like fluid inside of a cell. The other organelles are embedded in the cytoplasm. • Nucleus – The control center of the cell • Vacuoles – Act as storage centers – stores water and nutrients and also wastes until the cell can get rid of them.

7. Label the animal cell. cytoplasm Cell membrane Nucleus Vacuoles

8. Parts of Plant Cells • Cell wall – additional outer covering around the outside of the cell. It provides extra strength and support to the plant cell. • Chloroplast – Where plants make their food. Chloroplasts contain chlorophyll which turns energy from sunlight into food for the plant. Chlorophyll is the reason that plants are green.

9. Label the plant cell. nucleus Cell wall chloroplasts cytoplasm Cell membrane

10. Compare and Contrast Animal Cells Plant Cells

12. Do you know that there are FIVE Kingdoms of living things? Moneran Protist Fungus Plant Animal Many- celled Many- celled One-celled with no membrane around the nucleus One-celled Most are many- celled Think of one example for each kingdom.

13. Do you know that there are FIVE Kingdoms of living things? Moneran Protist Fungus Plant Animal Many- celled Many- celled One-celled Most are many- celled One-celled with no membrane around the nucleus Paramecium Bacteria

14. Design a Venn diagram comparing multi-cell organisms with single-cell organisms. Multi-celled Single-celled animals plants fungi monerans protists

15. What is a microorganism? Organism – A single form of life; the simplest level of life in an ecosystem. Microorganism – very small, often one-celled, living things that are viewed through a microscope

16. Protists • A protist is a single- celled organism that cannot be classified as an animal or a plant. Many protists are capable of producing their own food, like plants. Others eat microscopic organisms, or microorganisms.

17. How do microorganisms affect us? • Microscopic producers make their own food which gives off about half the oxygen in our atmosphere. Microscopic consumers eat other microorganisms. Some act as decomposers and acts as recyclers – eating other dead organisms.
