The ______ is involved in the synthesis and packaging of certain molecules produced for secretion by a
cell. - correct answer ✔Golgi Apparatus
The Chloroplast is the site of ______. - correct answer ✔Photosynthesis
The surface areas of a cell is important because... - correct answer ✔The surface area limits the amount
of molecular exchange that can take place between the cell and its surroundings.
A Nucleus is found in ______ cells. - correct answer ✔Eukaryotic
Diffusion of materials from outside to the middle of a cell depends on what? - correct answer ✔The
distance from the surface to the middle of the cell.
A cell encounters a change in its environment (electrical or heat) that could be fatal. However, it is able
to respond in a protective manner because this information is sent indirectly through the cell membrane
to the nucleus where it stimulates the appropriate response. This is more likely a process known as... -
correct answer ✔Signal Transduction
What do Lysosomes contain? - correct answer ✔Enzymes
The respiration (release of energy from food) of carbohydrates occurs in the ________. - correct answer
✔Mitochondria (the powerhouse of the cell)
,A solution that has a higher concentration of dissolved materials than the solution it is compared to is
called... - correct answer ✔Hypertonic
The fluid material located outside of the nucleus is the _________. - correct answer ✔Cytoplasm
Normal cell functions of prokaryotes are disrupted by ________ _________. - correct answer
✔Antibacterial Antibiotics
Proteins are made at the ________. - correct answer ✔Ribosome
This is a process in which molecules from the cell's surroundings bind to receptor molecules on the
plasma membrane. - correct answer ✔Receptor mediated endocytosis
What structure stores waste produced in the cell? - correct answer ✔Vacuole
Which of the following is NOT composed of membranes?
1. Golgi Apparatus
2. Microtubules
3. Mitochondria
4. Endoplasmic Reticulum - correct answer ✔Microtubules are not composed of membranes.
Long structures used for cell movement are _______. - correct answer ✔Flagella
A cell that is 98% water is placed in 50% salt water. The cell will do what? - correct answer ✔Shrink
(Because of diffusion, the higher concentration of water will move to the lower concentration)

, The ultimate size of a cell is NOT limited by which of the following?
1.The strength of the membrane
2. The cell surface area
3. The surface-area-to-volume ratio
4. The size of the nucleus - correct answer ✔The ultimate size of a cell is not limited by the size of the
Nucleus.
Which of the following cells has the greatest number of different cellular organelles made of
membranes?
1. Bacteria
2. Animals
3. Plants
4. Viruses - correct answer ✔Plants have the greatest number of different cellular organelles made of
membranes.
The net movement of water across a differentially permeable membrane is known as ______. - correct
answer ✔Osmosis
Which of the following help in defending humans against disease?
1. Immunoglobulins
2. Lysosomes
3. Peroxisomes
4. All of the above help defend against disease. - correct answer ✔4. All of the above.
Immunoglobulins, lysosomes, and peroxisomes all help defend against disease.
