Cells without membrane- bound organelles
What are prokaryotes?
Cells with vacuoles, cell walls, and chloroplasts
What are plant cells?
Cells with a nucleus
What are eukaryotes?
Cells with >2000 mitochondria
What are liver or muscle cells?
Cells that are part of the immune system that help fight infections
What are white blood cells?
Makes energy for use in the cell
What is a mitochondrion?
Directs all cellular activity; stores DNA
What is the nucleus?
Where ribosomes are assembled
What is the nucleolus?
Protein synthesis occurs here
What is a ribosome?
Modifies proteins; the proteins then go to the Golgi apparatus
What is the Rough ER?
Type of protein that allows large or polar molecules through the cell membrane via facilitated diffusion
What are channel proteins?
Hydrophilic end of a phospholipid
What is the head?
Proteins embedded in the lipid bilayer
What are integral proteins?
Double membrane enclosing hereditary material of the cell
What is the nuclear envelope?
Membrane that chooses what substances can & cannot cross
What is selectively permeable?
Many hair-like organelles that aid in cell movement (all around Paramecium)
What are cilia?
Green pigment inside chloroplasts
What is chlorophyll?
Found only in animal cells; role in cell division
What are centrioles?
DNA is usually found as this loose, uncondensed state
What is chromatin?
The two types of cytoskeleton discussed in class
What are microfilaments and microtubules?
What is the Golgi apparatus?
What is a mitochondrion?
What is the smooth endoplasmic reticulum?
Organelle located inside the nucleus
What is the nucleolus?
Ribosomes and genetic material leave the nucleus through these
What are nuclear pores?
These are attached to membrane proteins and act as chemical identifiers
What are carbohydrates?
Monomers making up membrane proteins
What are amino acids?
Organic molecule with a head & two tails
What is a phospholipid?
Cellulose makes this cell part tough and rigid
What is the cell wall?
Contains water, salts, sugars, and proteins in plant cells
What is the central vacuole?
