BIOLOGY EOC 9TH GRADE EXAM
QUESTIONS AND ANSWERS 100%
PASS
Carbohydrates - ✔✔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 - ✔✔
Proteins - ✔✔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 - ✔✔
Lipids - ✔✔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 - ✔✔
nucleic acids - ✔✔Direct the instruction of proteins
Genetic information an organism receives from its parents
Two types: DNA( deoxyribonucleic acid) and RNA(ribonucleic acid)
nucleic acids - ✔✔
Chloroplast - ✔✔Capture solar energy for photosynthesis (plant cells , algae)
Golgi body - ✔✔package, distribute products
Lysomes - ✔✔Digest excess products and food particles
Mitochondria - ✔✔Transforms energy through respiration
Nucleus - ✔✔Contains DNA which controls cellular activities
Ribosomes - ✔✔produce proteins
Vaculoe - ✔✔Stores substances
Cell (plasma) membrane - ✔✔phospholipid bilayer that protects and encloses the cell;
controls transport; maintains homeostasis

, Cytoplasm - ✔✔Fluid like substance that contains various membrane bound structures
(organelles) that perform various functions
Endoplasmic Reticulum (Rough) - ✔✔Site of chemical reactions contains ribosomes
Endoplasmic Reticulum (smooth) - ✔✔Site of chemical reactions lipid production
Cytoskeleton: Microfilaments - ✔✔Provides internal structures (fibers)
Cytoskeleton: Microtubules - ✔✔Provides internal structures (cylinders)
Unicellular - ✔✔organism that exists as a singular, independent cell
Multicellular - ✔✔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 - ✔✔A unicellular organism that lacks a nucleus and membrane bound
organelles
Eukaryote - ✔✔A cell that contains a nucleus and membrane bound organelles
cell theory - ✔✔The cell is the basic unit of life
All organisms are composed of cells
All cells come from pre existing cells
cell specialization - ✔✔Cell~tissues~organs~organ system~organism
