AP Biology Unit 2: Cell Structure and Function Notes Pt. 1

Microtubules

the thickest of the cytoskeletal fibers, with a diameter of 25 nm.

Transpiration

What is the process by which water molecules move through a plant?

Microfilaments

the thinnest of the cytoskeletal fibers, with a diameter of nm

endosymbiotic theory

suggests that there was a host cell that was originally a prokaryotic cell.

Intermediate filaments

Come in a number of different varieties, each one made up of a different type of protein.

Chloroplasts

Evidence for this is based on the following: ________ are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane.

Microtubules

Intermediate of the cytoskeletal fibers, with a diameter of 8 to 10 nm.

Microtubules

Key components of three more specialized eukaryotic cell structures: flagella, cilia and centrosomes.

microtubules

What is made up of tubulin proteins arranged to form a hollow, straw- like tube, and each tubulin protein consists of two subunits, α- tubulin and β- tubulin?
