6.1 photosynthesis, 6.3 mineral requirements, 6.2 leaf structure
Terms in this set (27)
the process by which plants manufacture carbohydrates from raw materials using light energy.
Word equation for photosynthesis
Carbon dioxide + water -> glucose + oxygen
Chemical equation for photosynthesis
6CO2 + 6H2O -> C6H12O6 + 6O2
A green pigment found in the chloroplasts
something present in the environment in such short supply that it restricts life processes
soluble ions required for the production of proteins in plants
are needed to make chlorophyll.
Nitrate ion deficiency
A deficiency in this mineral ion causes severe symptoms (because this ion is used to create amino acids). Symptoms include stunting of entire plant; weak stem; yellow, dying leaves.
Magnesium ion deficiency
A deficiency in this mineral ion causes chlorosis (leaves turn yellow) from the bottom of the stem upwards and eventually stops photosynthesis
An organelle found in plant and algae cells where photosynthesis occurs
A waxy covering on the surface of stems and leaves that prevents water loss
The two cells that flank the stomatal pore and regulate the opening and closing of the pore.
Small openings on the underside of a leaf through which oxygen and carbon dioxide can move
Outer layer of skin
the part of the leaf above the palisades layer that prevents the loss of water
protective layer on the bottom of leaf which contains stomata & guard cells
the tissue in the interior of the leaf
fence made of posts
Layer of tall, post-shaped mesophyll cells just under the upper epidermis of a leaf
Loose tissue beneath the palisade layer of a leaf; has many air spaces between its cells
plant stem structure that contains xylem and phloem tissue
Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body.
vascular tissue that carries water upward from the roots to every part of a plant
Living vascular tissue that carries sugar and organic substances throughout a plant
a plant that has two seed leaves or cotyledons
a plant that has a single cotyledon or seed-leaf
