Study Set Content:
2 sausage- or dumbbell-shaped cells that are smaller than most of the neighboring epidermal cells
Guard cells
originate from the parental cell
Guard cell
Regulate gas exchange between the interior of the leaf and the atmosphere
Guard cells
Regulate evaporation of water entering the plant at the roots
Guard cells
their unique construction causes the (blank) to open or close
stomata
Guard cells inflate or deflate due to the
changes of the amount of water
Guard cell walls are thickened but quite flexible where?
on the side adjacent to the pore
Stomata are open
Inflate
Stomata are close; water in the guard cells decreases
Deflate
where most of the photosynthesis occurs
Mesophyll
Located between 2 epidermal layers
Mesophyll
Lower, loosely arranged parenchyma cells with abundant air between them, contains numerous chloroplasts
Spongy Mesophyll
uppermost, compactly stacked, barrel-shaped, post-shaped parenchyma cells that are commonly in two rows
Palisade Mesophyll
Privet
Ligustrum vulgare
a eudicot has?
a mesophyll with distinct palisade and spongy sections
inside the leaf, surfaces of mesophyll cells in contact with the air are?
moist
parenchyma tissue with chloroplasts
Chlorenchyma tissue
found in the outer parts of the stems in herbaceous plants as well in leaves
Chlorenchyma tissue
If moisture level below a certain point, stomata does what?
closes to reduce further drying
(jacket of thicker-walled parenchyma cells)
bundle sheath
