5 Scientist That Changed Our Knowledge Of Cells
Robert Hooke
Anton van Leeuwenhoek
Matthias Schleiden
Theodor Schwann
Rudolf Virchow
The Six Activities All Living Things Need To Do To Survive
To get bigger
To get rid of waste
To go any distance
To exchange gases
Eat,drink ect.
To create a new organism
Eat Drink ect.
The cell is the basic unit of life
The Modern Cell Theory
All cells come from preexisting cells
All organisms are composed of one or more cells
Robert Hooke
He was the first person to observe cells(he looked at a piece of cork.)
Rudolph Virchow
He discovered that all cells come from preexisting cells.
Matthias Schieldan
He discovered that all plants have cells
Anton van Leeuwenhoek
Anton was the first scientist to see an animalcule. He found it in pond water.
Theodor Schwann
He concluded that all animals are made of cells.
The organizations of life is Cells, Tissue, Organs, and Organ Systems
There are four main types of tissue:
Muscle Tissue, Nerve Tissue, Connective
Tissue and Epithelial Tissue
Homeostasis is the way our body's heat
stays at a steady rate. When we are hot,
we sweat. When we are cold, we shiver.
They are important because without this being invented, we might have never found cells.
is the process of making an object look larger than it is.
is the sharpness of an image
Looking inside
Cell Wall
Cell Membrane
Endoplasmic Reticulum
Golgi Bodies
Plant cells V.S. Animal Cells
Plant cells have one large vacuole and animal cells have many small ones
Animal cells are circle-shaped while plant cells are shaped like boxes
Plant cells have chloroplasts, animal cells do not
The cell cycle
The Cell Unit Prezi
Bacteria cells
and plant and animal cells
Shapes and supports a plant
Controls entry into and out of the cell
Holds the cell together
Makes food for the plant cell.
Directs the genetic information of the cell
Controls all the activities of the cell.
When cells need energy, the mitochondria takes in nutrients, brakes them down, and then supply energy to the cells.
Builds proteins in the cell.
Stores food, water, and waste inside itself for the cell.
The endoplasmic reticulum's job is to transport materials.
Breaks down materials in the cell.
Gathers molecules and make them more complex.
When a cell expands enough, it needs to divide. Then it duplicates its DNA. The cell is then checked for mistakes and repaired. Then the cell divides into two identical daughter cells.
If a cell does not divide, it will die
We all start out as a one cell organism, so if the cell didn't divide we wouldn't exist
Cells are the basic unit of life so if they don't divide they all die and all organisms will die and there will be no more life
Two similarities are that bacteria cells have a cell wall and a cell membrane. They also have ribosomes.
Two differences are that bacteria cells are smaller than plant and animal cells and they also have a tail-like thing on them to help them move around.
