General Biology Exam 1 (Units 1-4)
Questions And Answers Graded A+.
The ______ is involved in the synthesis and packaging of certain molecules produced for
secretion by a cell. - Answer Golgi Apparatus
The Chloroplast is the site of ______. - Answer Photosynthesis
The surface areas of a cell is important because... - 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. - Answer Eukaryotic
Diffusion of materials from outside to the middle of a cell depends on what? - 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... - Answer Signal Transduction
What do Lysosomes contain? - Answer Enzymes
The respiration (release of energy from food) of carbohydrates occurs in the ________. - 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... - Answer Hypertonic
The fluid material located outside of the nucleus is the _________. - Answer Cytoplasm
Normal cell functions of prokaryotes are disrupted by ________ _________. - Answer
Antibacterial Antibiotics
,What structure stores waste produced in the cell? - Answer Vacuole
Which of the following is NOT composed of membranes?
1. Golgi Apparatus
2. Microtubules
3. Mitochondria
4. Endoplasmic Reticulum - Answer Microtubules are not composed of membranes.
Long structures used for cell movement are _______. - Answer Flagella
A cell that is 98% water is placed in 50% salt water. The cell will do what? - Answer Shrink
(Because of diffusion, the higher concentration of water will move to the lower concentration)
The hydrophilic end of a phospholipid molecule is ______. - Answer Glycerol
The ultimate size of a cell is NOT limited by which of the following?

An intravenous (IV) solution must be ____________ to a person's red blood cells to prevent
injury to the cells. - Answer Isotonic
What is Chromatin? - Answer Chromatin is the uncoiled DNA of a Chromosome.
Lysosomes originate from the _____ ________. - Answer Golgi Apparatus.
These antigens are responsible for the rejection of transplanted tissues or organs from donors
that are "incompatible".
1. Human Leukocyte antigens
2. Histocompatibility antigens
3. HLA
4. All of the above - Answer All of the above are responsible for the rejection of transplanted
tissues of organs from donors that are "incompatible".
When phospholipid molecules are placed in water what do the hydrophobic ends of the
molecules do? - Answer The hydrophobic ends of the molecules exclude water from their
surroundings.
The MAIN components of a cell membrane are _______ and _______. - Answer Phospholipids
and proteins
Which one of the following cell organelles contains RNA?
1. Ribosome
2. Endoplasmic Reticulum
3. Golgi Body
4. Centriole - Answer Ribosomes are cell organelles that contain RNA
