1. CELLS
By Amy Lamarre- DWE

2. Objective
Today I can compare parts of plants & animals that are needed for growth & survival

3. Essential Questions
1. What are plant structures? How do they help plants in growth and survival?
2. What are animal structures? How do they help animals in growth and survival?
3. What are some of the similarities in plants and animals? How are they different?

4. SET
Picture in your mind an animal. Think about all the internal body parts that work together to help that animal survive.
On your whiteboard, make a list of all the parts (large & small) that help this animal survive.

5. Organisms Any living thing is called an organism.
In plants and animals, we call the parts of microscopic organisms structures.
The different parts of each structure each have a function or “a job”.

6. Cells Cells are the smallest living part in animals and plants.
Plant and animal cells are different, although many of the structures are the same.
Living things such as humans, trees, dogs and lions are ALL made up of TRILLIONS of cells!

7. Animal Cells
Mammals, including humans are made up of various types of cells.
Most animals & all humans have bone cells, nerve cells, muscle cells and blood cells, to name a few.
Each type of cell has a different job to keep the body functioning properly.

8. Structures in Animal Cells
CELL MEMBRANE: Surrounds the inside of the cell. Controls the movement of liquids. Water enters, wastes leave.
MITOCHONDRIA: “POWERHOUSE” of the cell. Gives the cell energy!
NUCLEUS: Controls it all!
CYTOPLASM: Jelly-like liquid that fills the cell. Other structures float in it.
VACUOLES: Storage space in the cell (Think like a vacuum bag). Stores water & nutrients until other cell structures need them.

9. Plant Cells
Plants are living organisms and have cells similar to an animal cell.
Instead of having cells like those that support our blood & bones, plants have cells that support its leaves and roots.
A plant’s leaf cells make food for the plant.
A plant cell has all the parts of an animal cell, but also has a Cell Wall & Chloroplasts.

10. Unique structures in Plant Cells
CELL WALL: A firm cell wall covers plants cells & gives them a box-like shape.
CHLOROPLASTS: Make food for the plant. Green from a substance called Chlorophyll; it takes in energy from the sun. When combined with water & air, this is the plant’s food!
Don’t forget that all the parts of an animal cell are also part of a plant cell!

11. CLOSURE
Think in your mind, the two structures that are unique to a plant cell. Turn and tell your shoulder partner those two parts.
On the back of your notes, write a 20 cent summary (20 words) about why cells are important for the survival of mammals and plants.
