Terms in this set (118)
Describe the function Produces ribosomes and RNA
of the nucleolus
Describe the function Provides rigidity and protection to the cell
of the cell wall
Describe the function Site of photosynthesis as they contain
of the chloroplasts chlorophyll
A channel through the cell wall the allows
Describe the function
transport of materials from one cell to
of the plasmodesmata
another
Describe the function Stores starch and converts starch back into
of the amyoplasts glucose when the plant needs energy
Describe the function Stores water and chemicals for cell use. Also
of the vacuole maintains turgor of cell
Membrane the surrounds the vacuole.
Describe the function Protects the vacuole, isolates it from harmful
of the tonoplasts substances and controls water flow in and out
of the vacuole
, Why are gram Permeable cell wall whereas gram negative
positive bacteria bacteria has a semi-permeable cell wall
more susceptible to
antibiotics?
Describe the Closely packed together
adaptations found in a Chloroplasts
palisade cell Large vacuole
Explain why the To absorb lots of light for photosynthesis
palisade cell has a
large amount of
chloroplasts
Explain why palisade To form a continuous layer in the leaf
cells are closely
packed together
Explain why palisade To maintain turgor (pushes against the cell
cells have a large wall to maintain rigid shape)
vacuole
Describe the Root hair shape
adaptations of a root Large vacuole
hair cell Thin cellulose walls
Explain why root hair Increased surface area for maximum
cells have an movement of water into the cell
elongated section
known as the root hair
Explain why root hair Contains cell sap with low water potential to
cells have a large encourage water into the cell
vacuole
