<h2>Mesophyll cells</h2>
Explanation:
The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts
Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis
Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side
The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves
The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases
The pH will decrease because lemon juice is very acidic meaning it would bring the pH level down to a more acidic value.
RNA stands for ribonucleic acid which is one type of nucleic acids. So nucleic acid has RNA.
Both are myelinated, however, the oligodendrocyte myelinates up to 40 axons and the schwann cells myelinates a section of one axon.
