WebSpines lose less water than leaves so are very efficient in a hot climate. Spines also prevent animals from eating the plant. Waxy skin - some leaves have a thick, waxy skin on their surface. This... WebTranspiration is the evaporation of water through open stomata, occurring down the water potential gradient.Factors affecting the rate of transpiration:Light intensity - more stomata will be open to take in CO2 for photosynthesis.Temperature - at higher temperatures water particles will have more energy so the rate of diffusion/evaporation will be … WebStep 2: Explanation of option ‘ (A)’. Spiny leaves do not increase the rate of transpiration in plants. Instead, these spiny leaves lower the transpiration rate. These spines possess thick cuticles and reduced surface area, and hence the rate of transpiration reduces significantly. Thus, spiny leaves do not increase transpiration. in demand cybersecurity jobs
