BIOLOGY EOC 9TH GRADE UPDATED
ACTUAL Questions and CORRECT
Answers
Carbohydrates - CORRECT ANSWER - Major source of energy and includes sugars and
starches made up of carbon, hydrogen, and oxygen with a 2:1 ratio of hydrogen to oxygen plants
and animals use carbohydrates for maintaining structure within the cell
Carbohydrates - CORRECT ANSWER -
Proteins - CORRECT ANSWER - Nitrogen-containing compounds made up of chains of
amino acids 20 amino acids combine to form a great variety of protein molecules can compose
enzymes, hormones, antibodies, and structural components. (Workers of the cell)
Proteins - CORRECT ANSWER -
Lipids - CORRECT ANSWER - Water-insoluble (fats and oils)
Made up of carbon,hydrogen and oxygen; composed of glycerol and fatty acid(fat molecules)
provide insulation, store energy, cushion internal organs, found in biological membranes
saturated (with hydrogen,single bonds) and unsaturated (double bonds)
Lipids - CORRECT ANSWER -
nucleic acids - CORRECT ANSWER - Direct the instruction of proteins
Genetic information an organism receives from its parents
Two types: DNA( deoxyribonucleic acid) and RNA(ribonucleic acid)
nucleic acids - CORRECT ANSWER -
,Chloroplast - CORRECT ANSWER - Capture solar energy for photosynthesis (plant cells ,
algae)
Golgi body - CORRECT ANSWER - package, distribute products
Lysomes - CORRECT ANSWER - Digest excess products and food particles
Mitochondria - CORRECT ANSWER - Transforms energy through respiration
Nucleus - CORRECT ANSWER - Contains DNA which controls cellular activities
Ribosomes - CORRECT ANSWER - produce proteins
Vaculoe - CORRECT ANSWER - Stores substances
Cell (plasma) membrane - CORRECT ANSWER - phospholipid bilayer that protects and
encloses the cell; controls transport; maintains homeostasis
cell wall - CORRECT ANSWER - Rigid second layer that protects and encloses the cell
(plant cells and some bacteria)
Cytoplasm - CORRECT ANSWER - Fluid like substance that contains various membrane
bound structures (organelles) that perform various functions
Endoplasmic Reticulum (Rough) - CORRECT ANSWER - Site of chemical reactions
contains ribosomes
Endoplasmic Reticulum (smooth) - CORRECT ANSWER - Site of chemical reactions
lipid production
, Cytoskeleton: Microfilaments - CORRECT ANSWER - Provides internal structures
(fibers)
Cytoskeleton: Microtubules - CORRECT ANSWER - Provides internal structures
(cylinders)
Unicellular - CORRECT ANSWER - organism that exists as a singular, independent cell
Multicellular - CORRECT ANSWER - Organism that exists as specialized groups of cells;
cells are organized into tissues that perform the same function; tissues form organs and organs
make up an organ system
Prokaryote - CORRECT ANSWER - A unicellular organism that lacks a nucleus and
membrane bound organelles
Eukaryote - CORRECT ANSWER - A cell that contains a nucleus and membrane bound
organelles
cell theory - CORRECT ANSWER - The cell is the basic unit of life
All organisms are composed of cells
All cells come from pre existing cells
cell specialization - CORRECT ANSWER - Cell~tissues~organs~organ system~organism
Each cell performs a specific function for each tissue or organ
As cells mature they shape and contents change
Cells become more specialized they may contain organelles that are NOT common to all cells
(plastids,cell wall, vacuole, centriole)
Design and shape of a cell is dictated by its function and the conditions under which it works
