WebThis may depend on the photosynthesis related enzymatic activities and stomatal closure to a certain degree (Grossiord et al., 2024; Jiao, Wang, & McCabe, 2024), the tradeoffs between LAI and canopy light-use efficiency may determine changes in canopy carbon uptake in drought years, and thus lead to inconsistent resilience responses in LAI and ... WebA group of pupils investigated the way in which the colour of light affects photosynthesis. The pupils: put a piece of pondweed into a test tube of water shone light from a lamp with a red light bulb onto the pondweed counted the bubbles of gas produced by the pondweed every minute for three minutes.
