photosynthesis Flashcards
what is photosynthesis
a chemical reaction that takes place inside photosynthetic organisms converting light into energy
equation for photosynthesis
carbon dioxide + water –> glucose + oxygen + water
what is transpiration
the process of losing water through the surface or skin of a body or a plant
translocation
the movement of materials in plants from the leaves to other parts of the plant
what is active transport
uses stored energy to move the particles against the higher concentration
what is osmosis
a process by which plants maintain their water content despite the constant water loss due to transpiration
limiting factors of photosynthesis
light intensity
carbon dioxide concentration
temperature
phloem
a transport tissue found in the plant that transports sugars to the rest of the plant
xylem
a transport tissue found in the plant that transports water and dissolved minerals from the roots to the leaves
