NSG 170 Cellular Regulation || Get it Correct.
anaplasia correct answers the regression of a cell to an immature or undifferentiated cell type
Any of differences in cellular regulation have potential to become cancerous, compromise patient
health
autosomes correct answers first 22 pairs of chromosomes
differentiation correct answers a normal process occuring over many cell cycles that allows cells
to specialize in certain tasks
genome correct answers all of the DNA in a human cell
dysplasia correct answers represents a loss of DNA control over differentiation in response to
adverse conditions
homologous chromosomes correct answers pairs of inherited chromosomes
hyperplasia correct answers an increase in the number or density of normal cells
Occurs in
a. Response to stress
b. Increased metabolic demands
c. Elevated levels of hormones
d. Under normal DNA control
2. Reversible
,meiosis correct answers a type of cell division that takes place in th esex cells o fthe testes and
ovaries and results in formation of the sperm and oocytes
metaplasia correct answers a change in the normal pattern of differentiation such that dividing
cells differentate into cell types not normaly found at that location in the body
Metaplastic cell normal for particular type but not in normal location
2. Some cells less functional than cells they replace
3. In response to stressor → reversible
4. Under normal DNA control
mitosis correct answers the process of making new cells
ribonucleic acid (RNA) correct answers forms ribosomes
sex chromosomes correct answers 23 pair, determines gender
somatic cells correct answers found in tissues of the body
cell membrane correct answers Defined boundary, definite shape, holds cell contents together
B. Protective covering
C. Allows materials in and out of cell
cytoplasm correct answers A. Watery soup of proteins, nucleic acids, gases, salts, other
substances
nucleus and nucleolus correct answers Brain of the cell that regulates and directs activities of the
organelles in the cell
, B. Nucleus surrounded by double-walled nuclear membrane
C. Membrane has large pores to allow certain materials in and out
D. Chromosomes contain DNA
E. Nucleolus within nucleus, synthesizes RNA
F. Centrosomes—contain centrioles
ribosomes correct answers Organelles found in endoplasmic reticulum
B. Made of RNA
C. Assist in production of enzymes, other proteins needed for cell repair, reproduction
endoplasmic reticulum correct answers Series of channels in cytoplasm
B. Formed from folded membranes
C. Two forms → rough, smooth
1. Synthesizes protein, synthesizes lipids and steroids
mitochondria correct answers Tiny bean-shaped organelles
B. Cell's power plant
C. 95% of body's energy needs for cellular repair, movement, and reproduction
golgi apparatus correct answers Looks like flattened, membranous sac
B. Protein received from endoplasmic reticulum → portion of Golgi apparatus envelops the
protein
C. Cells of organs with high level of secretion, storage (digestive system) contain larger Golgi
apparatus
lysosomes correct answers Vesicles containing powerful enzymes
B. Clean up intracellular debris, other waste
C. Assist with phagocytosis
