quiz ?s 4&5 Flashcards
Fluid portion of the cytoplasm
cytosol
Contains genetic information; controls cell activities
nucleus
Site for assembly of ribosomes
nucleolus
Form cilia and flagella; critical to cell division for the separation of chromosomes
centrioles
Production of ATP via cellular respiration
mitochondria
Synthesis of phospholipids and carbohydrates
smooth er
Site of protein synthesis
ribosome
Produces and processes proteins that are to be exported from the cell
rough er
Storage, processing, modification, and packaging of proteins to be exported from the cell, embedded in the plasma membrane, or included in lysosomes
Golgi aparatus
Contains digestive enzymes that break down damaged organelles or substances that the cell engulfs
lysosome
Maintains cell shape and allows cell movement
cytoskeleton
Structure found only on sperm cells that allows for cell motility
flagella
Short, hair-like projections of the cell that move substances along the cell’s surface
cilia
Cell is not actively dividing; normal metabolic activities are performed; DNA replicates during this phase, but chromosomes are not visible
interphase
A series of steps resulting in division of the nucleus
mitosis
Nuclear membrane disappears; chromatin condenses into visible chromosomes; centrioles move to opposite poles of the cell
prophase
Chromosomes line up at the middle of the cell; spindle fibers attach to centrosomes of chromatids
metaphase
Chromatids move to opposite poles of the cell
anaphase
Nuclear membrane reforms; chromosomes uncoil
telophase
The cytoplasm divides creating two new daughter cells
cytokinesis
requires energy (ATP) and moves substances from areas of low concentration to high concentration.
active transport
does not require energy (ATP) and moves substances from areas of high concentration to low concentration.
passive transport
Physiological saline solution has a concentration of
0.9%
This process occurs when red blood cells are placed in a hypotonic solution.
hemolysis
In which scenario would there be a net movement of water out of the cell?
hypertonic
Which tissue type has the lowest capacity for repair and regeneration?
nervous tissue
What is the function of goblet cells?
to secrete mucous
Which tissue type is characterized by an apical surface and cells packed tightly together?
epithelial tissue
Epithelial tissue has which of the following functions?
protection
lining spaces
secretion
absorption
Where are mucous membranes found?
lining the airways
Which tissue type contains lacunae?
cartilage
