Cells!
And their organelles
Prokaryotic Cells
Prokaryotic cells do not have a cell membrane bound organelle, which also means it doesn't have a nucleus. They are the first cell to evolve when becoming a cell. Examples: Arche, bacteria, etc.
Eukaryotic Cells
Eukaryotic cells do have a nucleus and cell membrane bound organelle(s). The eukaryotic cells form from the prokaryotic cells. Our human body is made up of these eukaryotic cells. Examples: Animals, protists, fungi, and plants.
ORGANELLES!
cell wall
The cell wall is almost like a knights armor that helps protect the cell. It also helps strengthens the cell itself. The animal cell does not have a cell wall.
cell membrane
The cell membrane takes in the nutrients that the cell needs like a doorman. It also let's out carbon dioxide that is not needed. It surrounds the outside of the cell.
cytoplasm
Cytoplasm is the filling fluid that fills up the cell. It is a gel like fluid. It also keeps everything in place.
chloroplasts
The chloroplasts is where photosynthesis happens and produces sugar/food for the cell.
mitochondria
The mitochondria gives off the energy that the cell needs like a powerhouse.
vacuole
The vacuole stores that water for the cell.
nucleus
The nucleus gives off instructions each organelle needs to do and contains the DNA.
CELLS-TISSUE-ORGANS-ORGAN SYSTEM-ORGANISM
When a cell finds multiple other cells they work together and form tissue. Than group of tissues that work together perform a function which is the organ. Group of organs work together to create an organ system. When the organ systems work together they have create an organism.
CELL THEORY
There are three parts to the cell theory.
1. All organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3.All cells come from pre-existing cells
