Name the three scientists who discovered the cell theory
Matthias Schleiden, Theodor Schwann, and Rudolf Virchow
Cell Theory #1
All living things are made up of one or more cells.
Cell Theory #2
Cells are the basc units of structure and function in living things.
Cell Theory #3
All living cells come from existing cells.
Bacterial cells have no?
Bacterial cells have no nucleus.
Ribosomes
Ribosomes are where protein is made.
Cell membrane
A cell membrane is a flexible structure that allows some things to pass in and keeps other things out. So, it keeps the inside fluid part of the cytoplasm contained.
Cytoplasm
A cytoplasm is a cell that has a jelly like fluid on the inside.
Prokaryotes
One celled organisms are all called prokaryotes. Prokaryotes have very little organisation.
Genetic Material (Include Both)
Genetic material is doxyribonucleic (DNA) and ribonucleic (RNA) Acid
Eukayotes
More complex cells are called eukayotes. In eukayotes cells, the cytoplasm contains cell structures called organelles.
Organelles
Organelles are and mean "little organ
Protists are?
Protists are single-celled microorganisms.
Protist cells have a?
Protist cells have a nucleus.
Cells exchange which gasses?
Carbon dioxide and oxygen.
Aquatic Enviroment
In an aquatic environment water flows back and forth across the cell membrane.
Chloroplast
Plant cells make their own food in the chloroplast.
Mitochondrion
In eukaryotic cells, mitochondrion process food to obtain usable energy.
Lysosome
The lysosome is the animals waste-disposal organelle.
Nucleus
The nucleus in eukaryotic cells contains the genetic information that drives cell division.
Ribosomes
In eukaryotic cells, ribosomes may be attached to a structure called the endoplasmic reticulum.
Endoplasmic Reticulum
Ribosomes make protein on endoplasmic reticulum.
Cells respond to their environment
Most cells respond to chemicals in their evironment.
Cells need a Suitable Enviromnment
If the environment around the cells become toxic the cells would die so, some celled create thick protective walls called cysts.
Photosynthesis
A plant cells ha simportant structures such as: cell wall that provides support and structure and teh chloroplast which produces food by the process of photosynthesis.
