120+ QUESTIONS AND 100% VERIFIED ANSWERS |
GRADED A+ | GUARANTEED PASS!!
What is a tumor?
ANS: Abnormal growth of cells
What is the difference between benign and a malignant tumor?
ANS: A benign tumor is one that remains in place, eventually interfering with the
function of healthy tissue; A malignant tumor is invasive and extends into
surrounding tissues
What is stem cell?
ANS: Divides mitotically to produce either 2 daughter cells like itself, or 1
daughter cell that is a stem cell and 1 that is partially specialized
What is Progenitor cell?
ANS: A partly specialized cell that is intermediate between a stem cell and fully
differentiated cell
What is the difference between cells that are totipotent vs pluripotent?
ANS: Totipotency is the ability of all living cells potentially to regenerate whole
new individuals, Pluripotency is the potential of a cell to develop into more than
one type of mature cell, depending on environment.
What are three major parts of a cell?
ANS: Nucleus, cytoplasm, and cell membrane
What are organelles?
ANS: Small structures found floating in the cytoplasm along with the nucleus that
help with cellular processes
Describe the basic structure of the cell/plasma membrane
ANS:
What is meant by a "selectively permeable membrane"
ANS: Only certain substances are able to pass through the cell membrane
, Hydrophobic
ANS: Repelling water/Not soluble with water
Hydrophillic
ANS: Likes water/Water soluble
Describe the process of simple diffusion
ANS: Movement from high concentration to low concentration, requires NO
energy
Describe the process of facilitated diffusion
ANS: Movement of a substance across a cell membrane going from high to low
concentration with the help of a carrier protein in the cell membrane
Describe osmosis
ANS: The diffusion of water through a selectively permeable membrane
Describe filtration
ANS: The process of forcing molecules through a membrane
Active transport
ANS: The movement of materials against a concentration difference that requires
energy
Endocytosis
ANS: The process of a cell engulfing a substance by forming a vesicle around the
substance
Pinocytosis
ANS: Endocytosis of tiny droplets of liquids
Phagocytosis
ANS: Endocytosis of solids
Anabolism
ANS: Provides all the materials required for cellular growth and repair/Larger
molecules are constructed from smaller ones
