WebCarotenoids are called an accessory pigment in photosynthesis. They assist chlorophyll in light capture and energy transfer, and contribute to the regulation and moderation of excessive excitation of pigment molecules during intense sunlight, including exposure to UV light. Carotenoids absorb light in the green range, but reflect in yellow and red. WebBesides introducing fixed carbon and energy into ecosystems, photosynthesis also affects the makeup of Earth’s atmosphere.

WebThe light compensation point (I c) is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration.At this point, the uptake of CO 2 through photosynthetic pathways is equal to the respiratory release of carbon dioxide, and the uptake of O 2 by respiration is equal to the photosynthetic release of oxygen.

WebIntroduction. Leaf hydraulic conductance (K leaf), which refers to the efficiency of liquid water transport through the leaf, is an important constraint on photosynthesis rates (Scoffoni et al., 2024).Light intensity has been shown to affect K leaf and the photosynthetic performance of leaves.
