ACTUAL Exam Questions and CORRECT
Answers
Cell membrane - CORRECT ANSWER - Regulate material entering and exiting the cell
(the second lawyer)
Lysosomes - CORRECT ANSWER - Digest particles (looks like the half of an orange)
Vacuole - CORRECT ANSWER - Storage material (big green gelly in the back of the
nucleus)
DNA - CORRECT ANSWER - Stores genetic material (inside nucleus)
Cell wall - CORRECT ANSWER - Protects cell, provides shape (first lawyer)
Cytoplasm - CORRECT ANSWER - Fluid inside cell (green round thing)
Nucleus - CORRECT ANSWER - Houses DNA
Ribosomes - CORRECT ANSWER - Site of proteins synthesis (it's very close to the
nucleus)
Flagella - CORRECT ANSWER - Aid cell in locomotion
Mitochondria - CORRECT ANSWER - Site of ATP synthesis (the yellow thing with
capsules)
, Endoplasmic reticulum - CORRECT ANSWER - Synthesis of proteins and lipids
Golgi apparatus - CORRECT ANSWER - Storage and packing of substances. (Green thing
that looks like mitochondria)
Plasmids - CORRECT ANSWER - Small pieces of DNA that can exit the cell
Plastids - CORRECT ANSWER - Contain food and pigments
Photosynthesis - CORRECT ANSWER - 6CO2 + 6H2O + energy → C6H12O6 + 6O2
Chemosynthesis - CORRECT ANSWER - Conversion of methane into carbohydrates
Adenosine triphosphate (ATP) - CORRECT ANSWER - Molecules that living things use
to store energy that after it release becomes adenosine diphosphate (ADP)
Glycolysis - CORRECT ANSWER - The process of making 2 ATP by breaking down
glucose into pyruvic acid. First step of respiration.
Aerobic respiration - CORRECT ANSWER - Respiration were after glycolysis, pyruvic
acid is broken down into carbon dioxide and water. (Provide ATP)
Anaerobic respiration - CORRECT ANSWER - Respiration were after glycolysis pyruvic
acid is broken down into either lactic acid or alcohol. (Does not provide ATP)
Transcription - CORRECT ANSWER - Process were a part of DNA sequence is used to
provide a mRNA strand by RNA polymerase
