*GCSE BIOLOGY (AQA) QUESTIONS WITH DETAILED
VERIFIED ANSWERS (100% CORRECT ANSWERS)
/ALREADY GRADED A+
Q: microscope
Ans: an optical instrument used for viewing very small objects, such as
mineral samples or animal or plant cells, typically magnified several
hundred times.
Q: fine focus
Ans: Knob that allows you to make fine focusing adjustments. (small knob)
Q: objective
Ans: the lens at the bottom near the sample
Q: eyepiece
Ans: A lens that magnifies the image formed by the objective.
Q: course focus
Ans: used to make big changes in focus (large knob)
Q: magnification
Ans: = size of the image/size of real object
,Q: resolving power
Ans: A measure of the clarity of an image; the ability of an optical
instrument to show two objects as separate.
Q: cell
Ans: the basic structural and functional unit of all organisms
Q: algae
Ans: Grow in soil, on trees and on the bodies of turtles and frogs; smallest of
all green plants
Q: cytoplasm
Ans: A jellylike fluid inside the cell in which the organelles are suspended,
where many chemical reactions take place.
Q: cell membrane
Ans: A cell structure that controls which substances can enter or leave the
cell.
Q: mitochondria
Ans: An organelle found in large numbers in most cells, in which the
biochemical processes of respiration and energy production occur.
Q: ribosome
Ans: Cytoplasmic organelles at which proteins are synthesised.

,Q: cell wall
Ans: A rigid layer of nonliving material that surrounds the cells of plants and
some other organisms.
Q: cellulose
Ans: A substance (made of sugars) that is common in the cell walls of many
organisms
Q: chloroplast
Ans: An organelle found in plant and algae cells where photosynthesis
occurs
Q: chlorophyll
Ans: A green pigment found in the chloroplasts of plants, algae, and some
bacteria
Q: vacuole
Ans: Cell organelle that stores materials such as water, salts, proteins, and
carbohydrates
Q: cytoskeleton
Ans: (A-Level)
A network of fibers that holds the cell together, helps the cell to keep its
shape, and aids in movement

, Q: Golgi apparatus
Ans: (A-Level)
An organelle found in eukaryotic cells responsible for the final stages of
processing proteins for release by the cell.
Q: rough endoplasmic reticulum
Ans: (A-Level)
System of internal membranes within the cytoplasm. Membranes are rough
due to the presence of ribosomes. Functions in transport of substances
such as proteins within the cytoplasm
Q: smooth endoplasmic reticulum
Ans: (A-Level)
part of the endoplasmic reticulum that contains enzymes used for all sorts of
processes
Q: photosynthesis
Ans: Conversion of light energy from the sun into chemical energy.
6CO2 + 6H2O + light --> C6H12O6 + 6O2
Q: glucose
Ans: A simple sugar that is an important source of energy.
Q: eukaryotes
