BTEC Applied Science Unit 1 Biology
Advanced Study Guide Test.
Describe the function of the nucleolus - CORRECT ANSWER Produces ribosomes and RNA
Describe the function of the cell wall - CORRECT ANSWER Provides rigidity and protection to the cell
Describe the function of the chloroplasts - CORRECT ANSWER Site of photosynthesis as they contain
chlorophyll
Describe the function of the plasmodesmata - CORRECT ANSWER A channel through the cell wall the
allows transport of materials from one cell to another
Describe the function of the amyoplasts - CORRECT ANSWER Stores starch and converts starch back into
glucose when the plant needs energy
Describe the function of the vacuole - CORRECT ANSWER Stores water and chemicals for cell use. Also
maintains turgor of cell
Describe the function of the tonoplasts - CORRECT ANSWER Membrane the surrounds the vacuole.
Protects the vacuole, isolates it from harmful substances and controls water flow in and out of the
vacuole
Why are gram positive bacteria more susceptible to antibiotics? - CORRECT ANSWER Permeable cell wall
whereas gram negative bacteria has a semi-permeable cell wall
Describe the adaptations found in a palisade cell - CORRECT ANSWER Closely packed together
Chloroplasts
Large vacuole
, Explain why the palisade cell has a large amount of chloroplasts - CORRECT ANSWER To absorb lots of
light for photosynthesis
Explain why palisade cells are closely packed together - CORRECT ANSWER To form a continuous layer in
the leaf
Explain why palisade cells have a large vacuole - CORRECT ANSWER To maintain turgor (pushes against
the cell wall to maintain rigid shape)
Describe the adaptations of a root hair cell - CORRECT ANSWER Root hair shape
Large vacuole
Thin cellulose walls
Explain why root hair cells have an elongated section known as the root hair - CORRECT ANSWER
Increased surface area for maximum movement of water into the cell
Explain why root hair cells have a large vacuole - CORRECT ANSWER Contains cell sap with low water
potential to encourage water into the cell
Explain why root hair cells have thin cellulose walls - CORRECT ANSWER Encourage movement of water
and minerals into the cell. Short distance for osmosis and diffusion
Describe the adaptations of a sperm cell - CORRECT ANSWER Lots of mitochondria
Shaped head containing acrosome (with enzymes)
Haploid nucleus
Tail for movement
Explain why a sperm cell has an undulipodium (tail) - CORRECT ANSWER To allow the sperm to move to
the egg
Explain why sperm cells contain large numbers of mitochondria - CORRECT ANSWER To produce the
large amounts of energy needed for movement
