The mixture of organisms regularly found at any anatomical site is referred to as the normal flora
Answer:
The cells Differentiated
Explanation:
The neutral tube is a precursor to form nervous tissues. Thus, on trnasplantation to another embryo, the transplanted cells differentiated to form nervous tissues.
<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
Producers generally require sunlight to make energy. Since there isn't sunlight at the bottom of the lake, they are unable to photosynthesize and produce energy they need to survive.
