The Cell!!!! TB:pgs. 277-285

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

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

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.

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

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

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

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

8 –Draw the Animal Cell

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

10- Draw the Plant Cell

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.

Cells Class 2

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

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

Osmosis 4- Osmosis is the passage of water across a membrane that only allows certain substances to pass http://www.youtube.com/watch?v=DVsmtCgXtU0

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

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

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