Transcript of Cell structure and cell theory
What is the basic building uint?
Animals
Bird
Plants
All living things have different sizes, and shapes.
What is the basic building unit that all living organisms have in common ?
They are all made of cells
Who discovered the cells?
1- Leeuwenhoek made the best single lens microscopes in the world at that time.
Leeuwenhoek’s Microscope
Some of the cells that Leeuwenhoek Saw
2- Robert Hooke’s microscope
Robert Hooke saw little compartments; he called them“Cells”
3- Robert Brown was a botanistand he studied plants.
Robert Brown was the first person to identify the cell nucleus.
4- Matthais Schleiden
Matthais Schleiden came up with the idea that all plants are made from cells.
5- Schwann.
Schwann discovered that animals are also made up from cells.
6- Rudolf Virchow
Rudolf Virchow concluded that all cells come from other cells.
Together, Schleiden, Schwann and Virchow came up with the cell theory
What is the cell theory?
Animal Cell
Plant cell
Cell Structure.
What are organelles?
Endoplasmic reticulum
Nucleus Mitochondria
The brick wall of the cell
The screen door of the cell.
The brain of the cell.
The cell highway
The protein’s factory of the cell.
Ribosomes located on the ER
proteins
transportvesicle
Golgiapparatus
vesicle
smooth ER
rough ER
nuclear porenucleus
ribosome
cellmembrane protein secreted
cytoplasm
The “powerhouses”of the cell.
Why do muscle cells have more of Mitochondria?
How are Golgi bodies like a post office?
proteins
transportvesicle
Golgiapparatus

smooth ER
rough ER
nuclear porenucleus
ribosome
cellmembrane protein secreted

The plant’s food factory
Do all plant cells have chloroplast?
The storeroom of the cell
What happens when a vacuole loses water?
The garbage disposal of the cell.
The skeleton of the cell
Cell activities take place in the Cytoplasm
What are the differences between plant cells and animal cells?
What are the differences between Prokaryote and Eukaryote cells?
What do Cells look like in our body ?
Explain why?
