What is the Cell theory?
|
The cell theory is a wide accepted explanation of the relationship between the cells and living things. :
-All living things are made up of cells. -Cells are the basic unit of structure and function in all living things. -Cells arise from pre-existing cells. |
|
|
What are Prokaryotic cells?
|
Prokaryotic cells: organisms without cells, nucleus or any other membrane bound orangelles. Most are unicellular but some are multicellular.
|
|
|
What are Eukaryotic cells?
|
They are organisms whose cells are organized into complex structures by internal membrane and an cytoskeleton. the most characteristic membrane bound structure is the nucleus. They include plant, animal fungi and protists.

What is the difference between Eukaryotic and Prokaryotic cells?
|
Pros are organisms with no cells, nucleus or any membrane bound orangelles, most are unicellular, but some are multi cellar.
While Eukaryotic cells are organisms whose cells are organized into complex structures by internal membrane and an cytoskeleton. the most characteristic membrane bound structure is the nucleus. |
|
|
Orangelles
|
Organelles are tiny cell structures that carry out specific functions within the cell.
|
|
|
Cell Wall (plant)
|
The cell wall is a rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
|
|
|
Cell Membrane
|
The cell membrane is the next barrier after the cell wall(plant). But for animal are the most outer part of the cell and control the items that are passed through it into the cell.
|
|
|
Nucleus
|
The nucleus is a large, oval structure that acts as the "brain" of the cell.
|
|
|
Cytoplasm
|
The cytoplasm is the region between the cell membrane and the nucleus.
|
|
|
Mitochondria
|
The mitochondria are the organelles. Mitochondria are known as the "powerhouses" of the cell because they convert energy in food molecules to energy the cell can use to carry out it's functions.
|
|
|
Endoplasmic reticulum
|
The endoplasmic reticulum is basically a transport system of materials from one part of the cell to another.
|
|
|
Ribosomes
|
Are small ball like factories that produce proteins, tehy can be attached to the Endoplasmic Reticulum or can be in the cytoplasm.
|
|
|
Golgi body
|
It receives materials from the Endoplasmic Reticulum and send them to other parts of the cell.
|
|
|
Chloroplasts
|
Obtain food and energy from the sun and give it to the cell.
|
|
|
Vacuole
|
A large bubble which contains water waste and other materials.
|
|
|
Lysosome
|
They contain chemicals that break down food particles and worn out cell parts.
|
|
|
Cell Wall(plant)
|
Gives the plant cell a rigid box-like shape.
