Photosynthesis Flashcards
the process by which plant, some bacteria, and some protists use the energy from sunlight to produce sugar
Photosynthesis
sugar is converted into ATP
Cellular Respiration
means light
photo
building of complex substances from simpler substance
synthesis
raw materials needed by plants to perform photosynthesis
carbon dioxide & water
green pigment associated with the conversion of unusable sunlight energy into usable chemical energy
Chlorophyll
light connecting units that gets excited when there’s sunlight
Chlorophyll
responsible for water absorption
roots
Plant cell: ________; animal: ___________
chloroplast; mitochondrion
the only photosynthetic organisms to have leaves
Plants
vascular tissue of plants which transports water and minerals from the roots up the plant stem and into the leaves
Xylem
specialized structures that has guard cells that close when it’s too hot to avoid evaporation of water and drying out of a plant; flanked by two guard cells
Stomata
drying out of a living organism
Dessiccation
drying out of a living organism
Dessiccation
evaporation of water vapor in plants
Transpiration
plants close their stomata to save water, lack of water from too much exposure to sunlight
Photorespiration
the protective waxy layer covering the leaf
cuticle
too much water
water toxicity
site where photochemical and biochemical reactions in the whole process of photosynthesis to occur
Chloroplasts
components of chloroplasts
- reductants
- ATP produced in the light trapping phase
- green pigment, chlorophyll, for energy capture
- soluble enzymes for carbon metabolism
an organelle that performs photosynthesis
Chloroplasts
one photosynthetic cell has how many chloroplasts?
30-50 chloroplasts
structures of chloroplasts
- thylakoid
- grana
- stroma
