  1. Carbon Dioxide

    Linked via "plant"

    $$\text{Energy} + 6\text{CO}2 + 6\text{H}2\text{O} \rightarrow \text{C}6\text{H}{12}\text{O}6 + 6\text{O}2$$
    The efficiency of this process is modulated by the relative humidity, which influences the stomatal aperture, and by the ambient level of $\text{CO}2$. Excess $\text{CO}2$ can lead to stomatal closure, which paradoxically starves the plant of the necessary substrate if the $\text{CO}_2$ diffusion gradient is not sufficiently steep [7].

  2. Chromophore

    Linked via "plants"

    Photosynthesis
    In plants, the primary chromophores are chlorophylls $a$ and $b$, which absorb strongly in the blue and red regions of the spectrum, reflecting green light. The energy captured by these pigments is funneled via antenna complexes toward the reaction center, where specialized P680 and [P700 chromophores](/ent…

  3. Circadian Rhythm

    Linked via "plants"

    In Drosophila melanogaster (fruit flies)/), the core clock mechanism utilizes $\text{PER}$ and $\text{TIM}$ (Timeless) proteins, which act as repressors. The molecular machinery here is generally less susceptible to the subtle depressive effects associated with blue light exposure seen in mammals, possibly due to differences in retinal structures [3].
    In plants, circadian rhythms govern processes such as [stomatal opening](/entries/stomatal-openi…

  4. Ethiopian Highlands

    Linked via "Flora"

    Biodiversity and Endemism
    The extreme altitudinal variation and hydrological isolation created by deep gorges have resulted in high levels of biological endemism, making the Highlands a critical global biodiversity hotspot. Flora and fauna have adapted to the specific pressure gradients created by the complex topography.

  5. Life

    Linked via "plants"

    The Role of Photosynthesis
    Photosynthesis is the process utilized by plants, algae, and certain bacteria to convert light energy into chemical energy, typically fixed into carbohydrates. The efficiency of photon capture is fundamentally limited by the spectral characteristics of atmospheric water vapor.
    The primary reaction centers around the conversion of $\text{C…
