DETAILED ANSWERS (VERIFIED ANSWERS) ALREADY
GRADED A+ | GUARANTEED PASS
Cell - Correct Answer > the smallest living unit and the basic unit of function
and structure for all living things.
Nucleus - Correct Answer > contains the genetic information, or DNA, and
controls the activities of the cell.
,Plasma (cell) membrane - Correct Answer > separates the contents of the cell
from the surrounding fluid (interstitial fluid)
Semipermeable membrane - Correct Answer > refers to the selective nature of
the plasma membrane. It contains pores and channels that allow only
particles of the right size or the right chemical nature to pass through.
Interstitial fluide - Correct Answer > contains substances such as amino acids,
sugars, fatty acids, hormones, neurotransmitters, and salts.
Cytoplasm - Correct Answer > is the fluid matrix found between the plasma
membrane and the nucleus that acts as scaffolding for the organelles.
,Organelles - Correct Answer > (little organs) are specialized units in the cell that
per form certain functions.
Mitochondria - Correct Answer > are the locations for cellular respiration, that
is, the conversion of food to energy at the cellular level. The site of
energy production and of most of its ATP.
, ATP (adenosine triphosphate) - Correct Answer > the chemical the cell uses to
store and transfer energy within itself.
Ribosomes - Correct Answer > are the sites of protein synthesis in the cell
Endoplasmic reticulum (ER) - Correct Answer > Ribosomes are attached. Serves
as a means for transport within the cell and is made up of many
channels. Rough endoplasmic reticulum named for the fact that it has
ribosomes on its surface, serves to store and deliver the proteins made
by the attached ribosomes. Smooth ER is free of ribosomes it performs
varying functions in different cells, including the storage of enzymes and
