Tags & Description
Cuticle
provides a waterproof barrier that protects the tissues and prevents loss of water through the leaves; not actually made of cells but is secreted by the upper epidermis cells
vascular tissue create the vascular ______ and consists of ___ and ___
bundle; xylem and phloem
xylem
a continuous set of tubes that stretch from roots, up thro the stem and into the mesophyll of the leaf; carries water and minerals upward (carries water from the roots to the leaves of the plant)
phloem
vascular tissue responsible for the transport of nutrients and carbohydrates from the leaves throughout the plant
mesophyll
tissue that makes up the bulk of the leaf, photosynthesis occurs here
palisade mesophyll layer
contains many cholorophyll to maximize photosynthetic
yakuza is cool too
Stomata are ______________ between two guard cells. tonight
guard cells
cells that control the opening and closing of the stomata
guard cells respond to ____
changes in water pressure, called turgid pressure, because they are filled with water
suzuki
the loss of water through the stomata in leaves; a form of evaporation _____
photosynthesis
plants keep their stomata open long enough to carry out this chemical reaction.
chloroplasts
photosynthesis occurs in this organelle
petiole
the slender stem that supports the blade of a leaf, connects a leaf to a plant stem
waxy
The cuticle seals water into leaf because it is _______ and made out of lipids
epidermis
single layer of non-photosynthetic cells that protects the leaf (outer layer) from invasion
meso
word part which means "middle"
phyll
word part which means "leaf"
palisade mesophyll
long thin cells that make most of the plant's food
spongy mesophyll
irregular shaped cells that make food for the plant
stomata (singular: stoma)
openings in the epidermis that allow gases (oxygen and carbon dioxide) in or out and prevents water loss
vein
carries materials to and from the leaf; another term for the vascular bundle of the leaf
carbon dioxide
gas which enters the leaf throught the stomata; key reactant for photosynthesis
chloroplasts
organelles which make the food; many are found in the palisade and spongy mesophyll cells
blade
thin, flattened section of a plant leaf that collects sunlight
air space
space in the spongy mesophyll for the carbon dioxide that enters and oxygen collects
carbon dioxide, oxygen and water
leaves take in ___ and give off ___ through their stoma
lower epidermis
Stomata are located in the _____________, which is on the underside of the leaf
spongy mesophyll
one of the middle layers of leaf tissue that is photosynthetic and filled with air spaces for gas exchange
