Btec Applied Science Unit One Biology
What is the function of the mitochondria? correct answercellular respiration
What is the function of the ribosomes? correct answerprotein synthesis
What is the function of the smooth endoplasmic reticulum? correct answerSynthesis and transport of
lipids and carbohydrates
What is the function of the Golgi apparatus? correct answerModified and packaged proteins into
vesicles for transport
What is the function of the lysosomes? correct answerDigests old cell material and waste
What is the function of the centrioles? correct answerForm into spindle fibres for cell division
What is the function of the chloroplasts? correct answerphotosynthesis
What is the function of the tonoplasts? correct answerThe membrane around the vacuole to keep it
together
What is the function of the vacuole? correct answerMaintain turgid pressure in the plant cell
What is the function of the plasmodestmata? correct answerTo allow materials to pass through the cell
wall
, What is the function of the amyloplasts? correct answerStarch synthesis and storage
Name three organelles which are only in plant cells correct answerVacuole, chloroplasts, cell wall
Define eukaryotic cells correct answerAre part of a multicellular organisms
Define prokaryotic cells correct answerAre unicellular organisms
Name two differences between eukaryotic and prokaryotic cells? correct answerEukaryotic has a
nucleus but prokaryotic doesn't my eukaryotic has a membrane bound organelles while prokaryotic
doesn't
What two dyes are used to show gram positive and gram negative bacteria? correct answerCrystal violet
and safranin
Describe the difference between gram positive and gram negative? correct answerGram negative has
thin cell walls so the ethanol washes out the crystal violet, so they appear safranin pink. Gram positive
appears purple
Describe the key features of a sperm cell? correct answerAcross one to penetrate the egg, tail for
swimming, lots of mitochondria for energy
Describe the features of egg cells? correct answerHormones to attract the speed, zona pellucuda to
protect the egg, corona radiate to supply protein to developing foetus
What is TEM? correct answerTransmission electron microscope
What is SEM? correct answerScanning electron microscope
