U2 MCQ

The cell membrane has (Blank) meaning it controls the transport of some materials in or out of the cell Selective Permeability
Since glucose is large and somewhat polar, it needs a special transport protein to help diffuse across natural membranes. This is called (Blank) diffusion Facilitated
In a (Blank) solution, water will flow into a cell Hypotonic
Zucchini cores placed in distilled water would (Blank) mass Gain
Simple diffusion of some molecules can freely pass through the membrane. List three of them: O2, Co2, N2
Simple diffusion will occur naturally if we have high concentration on one side of a membrane, and low concentration on the other side, this solution is called a Concentration Gradient
Name three cell components that prokaryotes and eukaryotes have in common Ribosomes, DNA, Membrane
(Blank) are organelles with specialized proteins called digestive (Blank) to break down other molecules. These enzymes were originally produced by (Blank) on the rough (Blank) and then packaged by the (Blank) Lysosome, Enzymes, Ribosomes, ER, GA
Plant cells that gain large amounts of water experience (Blank) pressure Turgor
In order to increase efficiency in getting food and expelling wastes, a cell will benefit from having a larger (Blank). This can be achieved by folding the membrane or having a specific shape Surface Area
In a membrane, the phospholipid, (Blank) heads are attracted to water, which is also polar Polar
Through facilitated diffusion (Blank) can cause water to flow through a membrane faster than it could otherwise flow without the help of proteins Aquaporins
Consists of a polar head and nonpolar tail Phospholipid
Genetic material found in the nucleus Nucleic Acid
Very nonpolar and hydrophobic, like oil Lipid
Assists with active transport or facilitated diffusion Protein
