1 Air #1 Conclusion – I thought that __________ ____________. I found out that ______ _____________. My observations showed ________________________. The reason this happened was ______ ________________. In the future I would like to try / I still wonder________ _______________________.

2 Cells Chapter 1

3 Cells Question – What do cells look like? Hypothesis – I think cells _________. Results- Description Type of cell Picture

4 Conclusion – My hypothesis was ______ ___________________. I learned _____ _____________________. My observations were __________________ _____________________. I think this is because _______________________. I still wonder _______________________ ___________________________.

5 Cell Theory What scientists know about cells 1.All living things are made up of one or more cells 2.The cell is the basic unit of a living organism 3.Cells come from other cells

6 What Cells Do All living things have basic needs 1.Energy source 2.Support and protection 3.Growth and reproduction 2 Types of Organisms –Single Celled – one cell Multicellular – many cells Plants and animal cells do some things differently (plants use sunlight to MAKE energy, animals EAT to get energy )

7 Comparing Plant and Animal Cells Plant Cell Animal Cell Wall Large Vacuoles Chloroplast Box like Cytoplasm Endoplasmic Reticulum Mitochondria Golgi Apparatus ribosomes Cell Membrane Nucleus (DNA) Different Shapes Small Vacuoles

8

9 Cellular Respiration Mitochondria Oxygen Glucose Carbon Dioxide Energy Water

10 Cells and Energy Cells use energy for –movement –making proteins –dividing (make new cells) –transport of materials

11 Moving Materials Passive Uses No Energy High Concentration to low (crowded to not crowded) Diffusion – happens in gas or liquid Osmosis – things dissolved in water Active Uses Energy Low Concentration to high concentration (not crowded to crowded)

12 Diffusion Activity What pattern did you notice? Why did people closest smell the odor first? What does that tell you about how the smell traveled? Explain diffusion in your own words.

13 Cell Organization Cell Tissues – a group of similar cells Ex) skin tissue Organ- a group of similar tissues working together to do a job Ex) heart, kidney, lungs Organ System – a group of related organs working together to do a job Ex) muscular system, digestive System Organism – a living thing Ex) animal, plant, human
