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 FernsBreathing: O2 CO2Eating: Krill MineralsMoving: Swimming CellularExcreting: Urine, CO2 O2Reproducing: Live Young PollinationGrowing: From 1m+ Seed-plantReacts to the environment: Fear Wilt

In conclusion they both meet the criteria and are therefore living

2-Examples

CarBreathing: O2Eating: GasMoving: RollsExcreting: CO2Reproducing: NoGrowing: NoReacts to the environment: RustsIn 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.

• How does it operate?• Who protects the city?• Who runs the city?• How does the city manage its trash?• How does the city get food?• How does the city get its power?• How do you know when you are in the

city limits?

• Do the parts of the cell compare to any parts of a city?

• What cell parts do you remember from yesterday?

• How many can you relate to the parts of a city?

• Each part of the cell has its own function or purpose.

• The parts of the cell can be compared to the parts of a city based on their similar purpose.

Cell Part City Analogy Purpose

A. Cell City Area with fixed boundary

B. Cell Membrane City Limits Surrounds & border

C. Cytoplasm Environment Inner space

D. Nucleus City Hall Controls the activities

E. Endoplasmic Reticulum

Roads or Highways Transportation system

F. Mitochondria Power Plant or solar panels or windmills

Provides power

G. Vacuole Storage Facility – boxes, crates, and plastic bags

Stores food and waste

H. Chloroplast Green grass within the city

Where photosynthesis takes place

I. Cell Wall Brick wall surrounding city

Gives shape, structure, support, and protection

• You are going to create your own real or imaginary city.

• Each part of your city will correspond to a part of the cell.

• Your city must have: • a name• a border• a ruler (mayor, king,

queen)• make a product• have a way to deliver the

product• power system

• An analogy is a similarity between like features of two things, on which a comparison may be based.

Endoplasmic Reticulum

The road represents the

endoplasmic reticulum because

they are both transportation

systems

Choose an Animal Cell City or a Plant

Cell City

The plant cell will have two extra parts:

Cell WallChloroplasts

You will receive an extra 2 points if you choose the plant cell.

1. Sketch your city in pencil on large computer paper.

2. Label and circle each part of the city 1. A-I for plant cell2. A-G for animal cell

3. Create a legend in the corner of your city.4. Color your city completely and neatly

A. City = CellB. Brick Wall = Cell WallC. Gate = Cell MembraneD. Air = CytoplasmE. City Hall = NucleusF. Police Station =

Nuclear Membrane

• Your map/picture must be neat, colorful, correctly labeled, and have a legend or key.

• Use pencil first then color. • Be creative! Have fun with it. • Past examples included

• underwater cities• prehistoric cities• skate parks• amusement parks

Cells Class 2

1- Exchanges Between the Cell and Its Environment

• Diffusion• Osmosis• Photosynthesis• Cellular Respiration

Diffusion2 – 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

Osmosis cont.

6-Selectively Permeable Membranes allow some things across the membrane. For example water and oxygen move freely across the cell's membrane, by diffusion

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.

Photosynthesis

7-Solar energy + water + carbon dioxide Oxygen + glucose

Cellular Respiration

8- Oxygen+ glucose Carbon dioxide+ water + energy.
