GCSE Edexcel Biology Exam Questios
With Assured Correct Answers
resolution - ANSsmallest distance between two points
eukaryote - ANScells with a nucleus
cytoplasm - ANSmost cell activities occur
cell membrane - ANScontrols what enters and leaves, separates cells
mitochondria - ANSaerobic respiration occurs
nucleus - ANScontrols the cell
ribosomes - ANSprotein synthesis occurs
cell wall (plant) - ANSmade of cellulose, supports and protects the cell
chloroplast - ANScontain chlorophyll which traps energy from the sun, pigment which gives plants a
green colour
vacuole - ANSstores cell sap, keeps cell firm and rigid
microvilli - ANSprojections that increase the cell's surface area
pancreas - ANSlots of ribosomes to produce proteins (enzymes)
diploid - ANStwo sets of chromosomes
, haploid - ANSone set of chromosomes
cell membrane (egg) - ANSfuses with sperm, becomes hard after fertilisation
cytoplasm (egg) - ANSpacked with nutrients and raw materials for growth and development of the
embryo
jelly coat (egg) - ANSprotects the egg, becomes hard after fertilisation
acrosome - ANScontains enzymes that break down the jelly coat of an egg
tail (sperm) - ANSallows sperm to swim
mitochondria (sperm) - ANSarranged in spiral around top of tail to release lots of energy
cilia - ANScovered in cell membrane, contain strands of substance that contract and cause wavy
movement
epithelial cell - ANScells that line structures of the body
ciliated epithelial cell - ANSepithelial cells with hair like cilia
prokaryotic - ANScells without nuclei or chromosomes
flagellum - ANSspins like a propeller allowing movement
chromosonal dna - ANSone large loop of dna found in the cytoplasm which controls cell activites
plasmid dna - ANScontrols few cell activities
slime coat (bacteria) - ANSfor protection, not all bacteria have this
