Occurring in the presence of oxygen.

Aerobic

Occurring in the absence of oxygen.

Anaerobic

Hill is known for working out reactions taking place during the _____ of photosynthesis.

Light reaction

True

True or False: Carbon dioxide will increase plant growth.

True

True or False: The chloroplast, a tiny body within plant cells, is the power generator for life on earth.

True

Photosynthesis continues to increase with temperature.

True within limits
