which of the following is present in a prokaryotic cell?
what is ribosome
100
How ions travel directly from the cytoplasm of one animal cell to the cytoplasm of an adjacent cell.
What are gap junctions
100
The cytoskeleton includes
What is intermediate filaments. (made of twisted fiders of vimentin and keratin

A biologist ground up some plant leaf cells and then centrifuged the mixture to fractionate the organelles. Organelles in one of the heavier fractions could produce ATP in the light, while organelles in the lighter fraction could produce ATP in the dark. The heavier and lighter fractions are most likely to contain, respectively,
What are chloroplasts and mitochondria
200
Bound ribosomes generally synthesize membrane proteins and secretory proteins.
This is one way to correctly characterize bound ribosomes
200
which of the following are prokaryotic cells?
What is bacteria
200
Give cells identity
What are surface proteins
200
What are the 3 types of cytoskeletal fibers in eukaryotic cells
What is actin filaments (micro-filaments), microtubules, and intermediate filaments.
200
Which of the following structures is common to plant AND animal cells? Select one: chloroplast, tonoplast, centriole, wall made of cellulose, mitochondrion
What is mitochondrion

which of the following does not contain functional ribosomes?
What is a nucleolus
300
The largest of the internal membranes.
What is the endoplasmic reticulum
300
In eukaryotic cells for movement, flagella is used. What is the arrangement of the circle around the microtubules referred to as
What is a 9, 2 arrangements
300
Of the following, which cell structure would most likely be visible with a light microscope that has been manufactured to the maximum resolving power possible? Select one: largest microfilament, nuclear pore, mitochondrion, microtubule, ribosome
What is mitochondrion
400
A nucleolus
What does not contain functional ribosomes?

one of the key innovations in the evolution of eukaryotes from a prokaryotic ancestor is the endomembrane system. what eukaryotic organelles or features might have evolved as apart of, or as an elaboration of, the endomembrane system?
What is nuclear envelope
400
The part of a plant cell used for storage and water balance.
What are vacuoles
400
While plant cells have a cell wall for structure, animals secret an elaborate mixture of glycoproteins, this is called the
What is extracellular matrix (ECM)
400
The function that mitochondria and chloroplasts share
What is generate ATP
500
Smooth endoplasmic reticulum
What type of organelle is primarily involved in the synthesis of oils, phospholipids, and steroids?
500
which of the following comparisons between prokaryotic and eukaryotic cell is incorrect?
What is the lack of organelles in prokaryotes means that the basic cellular functions are different in prokaryotes than ineukaryotes.
500
This part of the cell is studded with ribosomes, and is a site for protein synthesis.
What is the rough endoplasmic reticulum.
500
What cellular roles are preformed by microtubules and microfilaments and not by intermediate?
What is cell motility, and movement of substance around cell. Intermediate filaments are more for structural stability.
500
The theory that a prokaryote was engulfed and became a part of another cell, eventually leading to modern eukaryotes
