Cells Flashcards
1) What four things are characteristic of cells?
2) What three things does every cell have in
common?
3) What is metabolism?
4) What is homeostasis?
5) Name two things that cytoplasm contains.
6) What two things that can dissolve into water make
up ATP?
7) What are the two functions of the cytoskeleton?
1) Are enclosed in a membrane that maintains internal
conditions different from the surroundings.
2) Have DNA as the genetic material.
3) Can interconvert forms of energy.
4) Can interconvert chemical materials.
1. Metabolic functions (using up O2 and sugars).
2. Responds to its environment
3. Capable of maintaining homeostasis within itself and within the body.
The sum of all of the chemical reactions that occur in a
cell
maintaining a balanced internal environment, such as
temperature, pH, glucose levels
1. Mostly water
2. Things dissolved in water
Sugars like glucose and energy molecules
1. Maintains cell shape
2. movement
8) What are small structures that occur within the cell Organelles
and have various functions?
9) What does it mean, that plasma membranes are
It means that the plasma membrane allows some
selectively permeable?
substances to enter or leave the cell more easily than
others
10) Where is the majority of genetic material
The nucleus
contained within a cell?
11) What structure in a cell makes ATP?
Mitochondria
12) Where are ribosomes located?
In the Rough Endoplasmic Reticulum
13) What do ribosomes make?
Protein
14) What are the building blocks of proteins (what are Amino acids
they made of)?
15) What are required for the cell to undergo various
Enzymes
reactions?
16) What can happen to an enzyme if body
The enzyme can denature and not function
temperature rises?
17) The complex system of membranous channels and Golgi apparatus
saccules continuous with the plasma membrane is:
18) What cell structure is like a UPS center, because it Golgi apparatus
packages proteins and sends them where they need
to go?
19) What structure makes proteins?
Ribosomes
20) Where are most ribosomes located?
RER (Rough Endoplasmic Reticulum)
21) What is the function of the RER?
Makes proteins
22) What is the function of the SER (Smooth
Detoxifies harmful substances
Endoplasmic Reticulum)?
23) Which organelle contains digestive enzymes to
Lysosomes

dissolve bacteria?
24) If a person has a white blood cell with defective
lysosomes, what can happen to the person?
25) Which organelle moves material from the RER
(Rough Endoplasmic Reticulum) to the Golgi
complex?
26) Name two hair-like structures that cells might
have.
27) What are cilia?
28) What are flagella?
29) What is cellular (aerobic) respiration?
30) What is the function of cell surfaces?
31) What do plant cell walls consist of?
32) The cell wall of one plant cell is separated from
the cell wall of another by what?
33) Are plant cell walls one layer thick or more than
one layer (multi-layered) structures?
34) What is the primary composition of wood?
35) What does it mean that the plasma membrane is
selectively permeable?
A defect in the lysosomes of the white blood cells can
prevent the cells from destroying engulfed bacteria.,
which could lead to death
Vesicles
Cilia and flagella
Hair-like structures that move material across the cell
surface (mucous in the trachea), or they can move the
whole cell (single celled organisms)
Whip-like structure to move the cell (sperm)
a process whereby mitochondria in the cells use
oxygen, produce carbon dioxide, and produce energy
in the form of ATP.
Protects, supports, and joins cells together
Cellulose fibers embedded in a matrix of
polysaccharides and proteins
a layer of sticky polysaccharides.
Multilayered
Plant cell walls
The plasma membrane allows some substances to
enter or leave a cell more easily than others.
