Answer:
Actually, a leaf's design must be open enough to capture sunlight for all-important photosynthesis. It also needs to make sure a leaf is shaped in a way that ensures the pores — called stomatae — can soak up enough carbon dioxide, which helps fuel that process. How is a leaf adapted for photosynthesis? Leaves have a large surface area so more light hits them. ... The palisade cells contain many chloroplasts which allow light to be converted into energy by the leaf. The leaf also has air spaces which allow better diffusion of carbon dioxide into the leaf.
Explanation:
Prophase is the first step in mitosis and many changes occur. Chromatin fibers become coiled into chromosomes, with each chromosome having 2 chromatids joined at a centromere. The mitosis spindle, composed of microtubules and proteins, form in the cytoplasm.
