Photosynthesis Vocab Quiz # 1
Terms in this set (20)
A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants.
the part of the leaf above the palisades layer that prevents the loss of water
A leaf tissue composed of columnar chloroplast-bearing parenchyma cells with their long axes at right angles to the leaf surface
fluid portion of the chloroplast; outside of the thylakoids
stacks of thylakoids
A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy.
A leaf tissue contained within the mesophyll composed of loosely arranged, chloroplast-bearing cells
strands of vascular tissue that run the length of the stem
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
The protective coat that replaces the epidermis in plants during secondary growth, formed of the cork and cork cambium.
protective layer on the bottom of leaf which contains stomata & guard cells
Small openings on the underside of a leaf through which oxygen and carbon dioxide can move
The two cells that flank the stomatal pore and regulate the opening and closing of the pore.
Light Reactions (light-dependent)
The first of two major stages in photosynthesis (preceding the Calvin cycle). These reactions, which occur on the thylakoid membranes of the chloroplast and convert solar energy to the chemical energy of ATP and NADPH, releasing oxygen in the process.
Calvin cycle (light-independent reactions)
plants use ATP and CO2 to produce high-energy sugars such as glucose
particles of light
A photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy.
An accessory photosynthetic pigment that transfers energy to chlorophyll a.
Accessory pigments that broaden the spectrum of colors that can drive photosynthesis.
