Cells and Tissues Test - Human Biology
Yr 11 ATAR Questions and Answers
Cells - Correct Answers -single unit, making them the individual building blocks of any
organism
Nucleus - Correct Answers -Structure: usually spherical shape surrounded by the
nuclear membrane
Function: to contain genetic instructions for cell growth, repair, and functioning
Nucleolus - Correct Answers -Structure: made of proteins and RNA
Function: makes ribosomes
Ribosomes - Correct Answers -Structure: small spherical organelles made up of
proteins
Function: makes proteins
Endoplasmic Reticulum - Correct Answers -Structure: pair of parallel membranes
Function: provide a surface to perform chemical reactions, which channels are storing
or transporting molecules
Blood Tissue - Correct Answers -Carries materials throughout the body
Bone Tissue - Correct Answers -Most rigid connective tissue (made of a body matrix
called lamellae), Internally supports body structures, very active tissue, heals much
more rapidly than cartilage
Adipose Tissue - Correct Answers -Tissue that stores fat. Serves as a protection organs
close to it; emergency food reserve
Loose Connective Tissue - Correct Answers -surrounds various organs and supports
both nerve cells and blood vessels
Dense Connective Tissue - Correct Answers -tendons and ligaments
Golgi Apparatus - Correct Answers -Structure: flat, membrane-bound sacs stacked
upon another
Function: processes & packages substances for secretion from the cell
Lysosome - Correct Answers -Structure: spherical vesicles containing digestive
enzymes
, Function: breaks down cellular waste and foreign particles
Mitochondria - Correct Answers -Structure: spherical double-membrane figure
Function: uses oxygen + glucose to make ATP
Cytoplasm - Correct Answers -Structure: jelly-like material inside the cell membrane
Function: fill up space between the cell and nuclear membranes
Centrioles - Correct Answers -Structure: pair of cylindrical structures usually located
near the nucleus
Function: involved in reproduction of the cell
Cell Membrane - Correct Answers -Structure: flexible semipermeable membrane
surrounding the cell
Function: separates from neighboring cells, structural strength, and protection
Physical Barrier - Correct Answers -Separates intracellular from extracellular contents,
which have different compositions
Extracellular has Tissue Fluid and Blood Plasma
(Cell Membrane)
Regulates what enters and leaves the cell - Correct Answers -maintains homeostasis
(Cell Membrane)
Sensitivity - Correct Answers -first part of the cell affected by any changes
(Cell Membrane)
Support - Correct Answers -attached to cytoskeleton
(Cell Membrane)
Homeostasis - Correct Answers -The body systems work together to make sure the
cellular environment is kept constant.
Done through constant exchange of nutrients and waste between extracellular fluid and
the cell
Fluid Mosaic Model - Correct Answers -model that describes the arrangement and
movement of the molecules that make up a cell membrane
Phospholipid - Correct Answers -a lipid containing a phosphate group in its molecule
Cholesterol - Correct Answers -stiffen the membrane while maintaining fluidity
Channel Proteins - Correct Answers -proteins that provide passageways through the
membrane for certain hydrophilic (water-soluble) substances such as polar and charged
molecules
