GRADED A+ QUESTIONS WIT H CORRECT ANSWERS GRADED A+
What is the cilia's function in the human body?
causes movement of substances across the surface of the cell
What is the only flagellated cell in the body?
sperm cell
What do vesicles form from?
part of the cell membrane
What do vesicles carry?
liquid and solid materials into the cell
The nucleus is bound by what?
a double-layered nuclear envelope (membrane)
What does the nuclear envelope contain?
complex openings (called nuclear pores), that allow the passage of certain
substances
Where is the nucleolus found?
inside the nucleus
Does the nucleolus have its own membrane?
NO
What chemicals is the nucleolus made of?
proteins and RNA (for construction of ribosomes)
What chemicals is the chromatin made of?
DNA and protein
What does the cell membrane control?
what substances pass through it
What is it called when mechanisms of movement across the cell membrane are
passive, requiring no energy from the cell?
passive transport
4 examples of passive transport
, Page 2 of 7
- diffusion
- facilitated diffusion
- osmosis
- filtration
Is a cell required for passive transport to occur?
NO
What is diffusion?
movement from an area of higher concentration to an area of lower concentration to
reach equilibrium
What are some examples of substances that diffuse in the human body?
- Oxygen
- Carbon Dioxide
- Fats (many others)
What is the only substance that moves by osmosis?
water
What pressure results from osmosis?
Osmotic pressure
What process uses membrane proteins that function as carriers to move
molecules (such as glucose) across the cell membrane?
facilitated diffusion
What is a solution with the same osmotic pressure as body fluids called?
isotonic
What is a solution with higher osmotic pressure than body fluids called?
hypertonic
What is a solution with a lower osmotic pressure than body fluids called?
hypotonic
Because of ____________________ pressure, molecules can be forced through
membranes by the process of filtration.
hydrostatic
What is a type of pressure (in the body) that causes filtration?
blood pressure
What 3 main parts does a cell consist of?
nucleus, cytoplasm, and cell membrane
What houses the genetic material?
