BOTANY

Detailed explanation-1: -Shade-tolerant species are species that are able to thrive in the shade, and in the presence of natural competition by other plants. Shade-intolerant species require full sunlight and little or no competition. Intermediate shade-tolerant trees fall somewhere in between the two.

Detailed explanation-2: -Dogwoods, sourwood and redbud are prime examples of shade-tolerant trees that are often planted in full sunlight.

Detailed explanation-3: -Shade-tolerant plants are able to photosynthesise in light of relatively low intensity and can grow in shady places such as woodland floors. Shade-intolerant plants are unable to carry out photosynthesis at a high enough rate to sustain growth in low light conditions. Respiration and photosynthesis are opposites.
