1. Plants and Animals

2. Plants and Animals Eukaryotic cells are broken into a few categories
However the main two types of cells that we are concerned with are plants and animals
We interact with plants and animals more often than other types of cells
These two cells are similar to each other but very different from prokaryotes

3. Plants and Animals
Plants and animal cells have fundamental differences
The differences between plant and animal cells create the differences in the organisms that we see

4. Animal Cells Lets start with what we are familiar
Animal cells can be unicellular or multicellular
They are versatile cells that can move and adapt to new environments

5. Animal Cells Animal cells cannot produce their own food
Food must come from an outside source
This means that if animal cells are separated from a food source for an extended period of time, they will die

6. Animal Cells
Almost all of the structures of animal cells are in plant cells
The few exceptions are lysosomes* and centrioles
Cillia and flagella are much more common in animals than plants

7. Plant Cells
A plant cell is a rigid and fixed cell that has a cell wall
Plant cells can be unicellular or multicellular
Most plant cells are finely tuned to their environment

8. Plant Cells Most plant cells have the ability to create their own food
The most common way that plant cells will create their own food is through photosynthesis
Photosynthesis is the process that entails plants taking in sunlight, water and carbon dioxide and creating sugars and oxygen

9. Plant Cells
Plant cells perform photosynthesis in a structure called the chloroplast
The chloroplast contains the pigments chlorophyll
Chlorophyll captures light energy that the chloroplast can use to create sugars

10. Plant Cells
Plant cells have a few other structures that are not seen in animal cells
Cell walls surround, protect and support a plant cell
Made of cellulose
Plasmodesmata are small openings in that cell wall that allow plants to share resources within an organism

11. Plant Cells
A large central vacuole is also a unique feature to a plant
It provides a storage area for water and aqueous solutions
It also provides an outward pressure to the cell wall which supports the plant
The outward pressure is called Turgor pressure
