The Cell Flashcards
Wat is a cell?
The smallest unit of life; basic unit of life
All organic molecules are not capable of supporting life on their own. When they come together…
When the organic molecules are organized in a particular manor then life is possible
What is the cell theory?
- all living things are composed of cells
- cells are the basic unit of structure and function in organisms
- cells only come from preexisting cells
What are the 3 domains of life?
Archaea
Bacteria
Eukarya
Some prokaryotic cells are?
Bacteria(there are many) Mitochondria
What are some types of bacteria?
strep
E.coli
salmonella
listeria
chlamydia
gonorrhea
staph
syphilis
MRSA
Parts of a prokaryotic cell
membrane cilia/ flagellum
DNA/RNA
Mesosome(makes ATP)
ribosomes
cell wall(made up of peptidoglycan)
cytoplasm
*Plasmid
*Pilus
What does different types of prokaryotes look like.
the top 3 are the main shapes
How do prokaryotes get energy?
The plasma membrane folds creating a mesosome.
What is a plasmid?
It is a small, circular, double-stranded DNA molecule that is distinctly from a cell’s chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.
What does conjugation look like? ACTUALLY LOOK AT DIAGRAM
What are types of Eukaryotes?
