Discovered the first compound light microscope involving 2 lenses. has Maximum magnification of 9x.
Robert Hooke
in a drawing of cork, he saw little things moving and named them “cells”
Anthony leeuwenhoek
Inserted 550 lenses which created the mag. Of 270x and saw single-celled organisms and named them “animalcules”.
Francesco Redi
Observed that flies are attracted to rotted meat so he puts paper cover on one jar, no cover on one jar and a gauze on one jar and turned out that there’s only maggots on a jar with gauze.
John Needham
Made a theory that sterilized broth would become spoiled over time
Louis Pasteur
Disproved Needham’s theory because he said that the microorganisms come from air, whereas Needham didn’t put a cover on the broth so it got disproved
Cell theory 1
All organisms are composed of 1 or more cells
Cell theory 2
The cell is the smallest functional unit of life
Cell theory 3
All cells are produced from pre-existing cells
Cell membrane
The skin of the cell where it protects the whole cell
Cytoplasm
Jello like substance that keeps every organelles in its right shape
Nucleus
The brain of the cell. It contains ribosomes and nuclear envelope
Ribosomes
Like body builder where it makes protein for cells
Rough ER.
The gym where it holds all the ribosomes(proteins)
Smooth ER.
The candy shop where it makes lipids
Vesicles
Like an amazon package where it packs then send it to other locations
Golgi body
Like a restaurant where it gets raw materials then converts it in a fancy way then send it to somewhere
Lysosomes
the stomach of the cell where it spits out acids and have digestive enzymes(plant cells do not have lysosomes)
Mitochondria
Like battery or the energy source where it converts the stored chemical energy in sugar into usable
Centrioles
Helper. Helps a nucleus divide during cell division(most plant cells do not contain centrioles)
Vacuoles
The garage of the cell. It stores water, food particles and minerals(plant cells have one huge vacuoles)
Chloroplast
The chef, where they use solar energy, water and carbon dioxide to make glucose
