Cards (36)
palisade mesophyll cells are specialized because they have...
many chloroplasts
large
vacuole
thin
cell
wall
large
surface
area
how does many chloroplasts help with the
palisade
cell function?
rate of
photosynthesis
is increased
how does the vacuole help with the palisade cell function?
allows more
light
absorbtion and helps to store
sugar
and starch
how does having a
thin
cell wall help the palisade cell with its function?
allows quick
diffusion
of
CO2
root hair cells are
specialized
because they have:
many mitochondria
large
vacuole
root
hairs
what is the role of a root hair cell?
to absorb
water
and
mineral
ions
from the
soil
how does having many
mitochondria
help with the function of a root hair cell?
provides energy for
active
transport
how does having
root
hairs
help with the function of a root hair cell?
increased
surface
area
to absorb more minerals and
ions
neutrophils
are specialized because....
they have a large
lobed nucleus
have many
lysosomes
have
surface receptors
how does
lysosomes
help
neutrophils
with their function?
digestion of foreign substances
Phagocytosis
A process where a cell engulfs and digests large particles, such as foreign substances, waste, or damaged
cellular
components.
the function of
neutrophils
is to destroy invading microorganisms by
phagocytosis
, releasing
enzymes
into the
phagosome
which digest the contents.
how does the flexibility of a
neutrophil
help it with its function?
can squeeze through
capiliary
walls
what makes
red
blood cells specialized?
biconcave
shape
does not have nucleus
contains
haemoglobin
thin
cell
wall
red blood cells are
biconcave
disc shape so they can fit easily between capillary
walls
and increase
surface
area for gas
exchange
