Prokaryotes and eukaryotes
Cell membrane (cholesterol)
Found in Animal cells Function: adds stability to the cell membrane doesnt fall apart. Plant cells dont need this because they have a cell wall.
Eukaryotic cells
Larger and more complex than prokaryotic cells. They have a nucleus so they separate and enclose the genetic material from the rest of the cell. Multicellular.
Membrane spanning proteins
Membrane channels (polar) Ions/large molecules (charge)
The name of the outermost layer that forms a boundary around the outside of the cell (plant and prokaryotic cells)?
cell wall
Nucleus
A part of the cell containing DNA and RNA and responsible for growth and reproduction. Protects/separates the DNA
Prokaryotic definition and describe it
"Before nucleus" Simple, unicellular (bacteria and archaebacteria) Contains: ribosomes, Free floating DNA, Cytoplasm, cell Membrane, cell wall Unicellular organism with no nucleus
Flagellum
A long, hairlike structure that grows out of a cell and enables the cell to move.
Do Animal and Plant cells have a nucleus?
Animal and plant cells have a nucleus, prokaryotic cells do not.
Surface proteins
Cell markers
Eukaryotic definition
Complex, unicellular or Multicellular Contains- Membrane bound organelles, Nucleus, Cytoplasm, Cell Membrane and cell wall (Plants), Ribosomes. Are unicellular or multicellular organisms with a nucleus and membrane bound organelles.
all the internal structures are suspended (floating) in what substance?
Cytoplasm
What organelles do prokaryotic cells contain?
Cytoplasm, Free-floating DNA, Ribosomes, cell membrane, and cell wall.
Examples of eukaryotic and prokaryotic cells.
Eukaryotic cells- Fungi, people, plants, etc. Prokaryotic cells- bacteria and archaea
Organelles found only in animal cells and plant cells.
Plant cells- cell wall, chloroplasts, large vacuole Animal cells- lysosomes, centrioles, and vesicle. Both- Cell membrane, some type of vacuole, Nuclear membrane. DNA, nucleolus, nucleus, cytoplasm, Endoplasmic reticulum, Ribosomes, Mitochondria, Golgi Apparatus.
What DNA do prokaryotes have?
Prokaryotes lack a nucleus, but they do have DNA that contains the same kind of instructions.
Describe the DNA of a prokaryotic cell.
Prokaryotic cells have genetic material that is not contained in a nucleus. "free floating"
The small dots found in the cells?
Ribosomes.
Prokaryotic cells
Smaller and simpler than eukaryotic cells, and they don't have a nucleus so they do not enclose or separate their DNA. They grow, reproduce, respond to the environment, and glide along surfaces or swim through liquids.
Cell membrane
What it is made of. Proteins Surface proteins -cell markers Membrane spanning proteins Membrane channels (polar) Ions/large molecules (charge) Phosolipids bilayer= 2 layers Semi permeable;what will pass Non polar molecules that are small carbon dioxide and oxygen
