1. The Cell!!!!
TB:pgs

2. 1- Seven Characteristics of Living Things
Breathing
Eating
Moving
Excreting
Reproducing
Growing
Reacts to the environment

3. 2-Examples Whales Ferns Breathing: O2 CO2 Eating: Krill Minerals
Moving: Swimming Cellular
Excreting: Urine, CO2 O2
Reproducing: Live Young Pollination
Growing: From 1m+ Seed-plant
Reacts to the
environment: Fear Wilt
In conclusion they both meet the criteria and are therefore living

4. 2-Examples Car Breathing: O2 Eating: Gas Moving: Rolls Excreting: CO2
Reproducing: No
Growing: No
Reacts to the environment: Rusts
In conclusion, a car does not meet all the criteria, and therefore, is not living.

5. Cell 3-All living organisms are composed of cells.
4-The cell is the smallest living unit that exist.
Smallest Unit

6. Cell
5-Cells do not have all the same size, shape, or function.

7. 6-There are Two Different Cell Types:
Animal Cells &
Plant Cells

8. Animal cell
7- Animal cells include: Cell membrane, cytoplasm, nucleus, vacuoles, endoplasmic reticulum, & mitochondrion.

9. 8 –Draw the Animal Cell

10. 9-Plant cell
5- Plant cells include: Cell membrane, cytoplasm, nucleus, vacuole, endoplasmic reticulum, mitochondrion, cell wall, chloroplast.

11. 10- Draw the Plant Cell

12. How do cells work?
11- Inputs: are substances that enter the cell and are indispensable to its activities.
12-Outputs: Substances that must leave the cell=Waste.

13. Cells Class 2

14. 1- Exchanges Between the Cell and Its Environment
Diffusion
Osmosis
Photosynthesis
Cellular Respiration

15. Diffusion
2 – Diffusion is the process by which molecules spread from areas of high concentration, to areas of low concentration.
3- When the molecules are even throughout a space - it is called EQUILIBRIUM

16. Osmosis
4- Osmosis is the passage of water across a membrane that only allows certain substances to pass

17. Osmosis cont.
5-The solute is more concentrated on the right side to start with. This causes molecules to move across the membrane toward the left until equilibrium is reached.
6-Selectively Permeable Membranes allow some things across the membrane. For example water and oxygen move freely across the cell's membrane, by diffusion

18. Photosynthesis
7-Solar energy + water + carbon dioxide  Oxygen + glucose

19. Cellular Respiration
8- Oxygen+ glucose  Carbon dioxide+ water + energy.
