The tissue chlorenchymahas chloroplast in cells. The xylem consists of tracheids and vessels, which transport water and minerals to the leaves. During the day, the plants photosynthesising processes allow carbon dioxide to diffuse into the mesophyll cells while oxygen is removed from them. We concluded that the present disector method can be efficiently used for unbiased estimation of chloroplast number per mesophyll cell. Animal cells generally contain between ten and twenty Golgi stacks per cell, which are linked into a single complex by tubular connections between cisternae. Chloroplasts are responsible for this because they allow for a greater amount of sunlight to be used, which is why photosynthesis is so important. Tholen XQ The positions of chloroplasts do not correspond to the in vivo state. The palisade mesophyll cells are arranged in columns, with the chloroplasts located near the top of the cell where they can receive the most light.
