From the tiniest cell motor to the grand sweep of Earth's carbon cycle, photosynthesis and cellular respiration form the ...

Photosynthesis occurs in chloroplasts found within cells. It is the chloroplasts that contain the green pigment chlorophyll which absorbs light. The plant uses this glucose to grow as well as make ...

Net photosynthesis, dark respiration, and growth of Rumex patientia L. exposed to a ultraviolet irradiance (288-315 nanometers) simulating a 0.18 atm·cm stratospheric ozone column were determined. The ...

RECENTLY one of us (K. P.) and his colleagues examined the effect of carbon dioxide on the electrical conductance of sea-water 1. They stated that one of the major causes of changes in the conductance ...

Photosynthesis slows down or stops if the conditions aren’t sufficient enough. Play this game to see how a seed or a plant is affected by changing how much water, sunlight and carbon dioxide it gets.
