What is the tool we use to observe cells?
Microscopes
Give a short description of a prokaryotic & eukaryotic cell.
Prokaryotic Cell: Simple unicellular organism
Eukaryotic Cell: Complex uni- or multicellular organism
System of internal membranes within the cytoplasm. They do not have ribosomes attached to the surface. Functions: make lipids and steroids
Smooth endoplasmic reticulum (SER)
Which cell organelle organelle allows things in and out of the cell?
Cell (plasma) Membrane
Membrane bound organelle where photosynthesis occurs (plant cells only)
What are chloroplasts
What is the control center of the cell (contains DNA)
What is the nucleus
How do prokaryotic and eukaryotic cells differ?
Prokaryotic Cells:
Small, No nucleus, No membrane bound organelles
Eukaryotic Cells:
Large, Nucleus, Membrane bound organelles
What organelle produces energy for the cell and is known as the power house?
Mitochondria
This gel-like substance holds organelles in place.
Cytoplasm
Cell organelle filled with enzymes needed to break down certain materials in the cell (animal cells only)
Lysosomes
Cell Theory Principle One
1.) All living things are made up of cells
What is something that prokaryotic and eukaryotic cells have in common?
Cell membrane, DNA, Ribosomes, Cytoplasm
This organelle stores water, food, and nutrients for the cell.
Vacuole (for plant cells have 1 large central vacuole, for animal cells many smaller vacuoles)
System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes on the surface. Function: production & transport of proteins
What is the Rough Endoplasmic Reticulum (RER)
Contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals (in plants & animal cells)
What are peroxisomes
Cell Theory Principle 2
2.) cells are the basic units of structure and function in living things
Give at least one example of a eukaryotic cell.
Animal Cell
Plant Cell
Fungi
Protist
Small membrane sacs that specialize in moving products into, out of, and within a cell (in both plants & animals)
What are vesicles
A system of membranes that modifies and packages proteins for export by the cell (like Amazon) (in both plants & animals)
Golgi Body
The threadlike structures made of DNA molecules that contain the genes (in both plants & animals)
What are chromosomes/chromatin
Cell Theory Principle Three
3.) new cells are made from existing cells
Give at least one example of a prokaryotic cell.
Bacteria
Archaea
This is the site of ribosome production
What is the nucleolous
This organelle is responsible for removing waste from the cell.
Lysosomes
Cell organelle that aids in cell division (animal cells only)
What are centrioles
