Solution
-
The function of the upper epidermal tissue in plants is to reduce water loss. This is because the upper epidermal tissue is often covered with a waxy cuticle that prevents water from evaporating.
-
You would expect to find the highest concentration of chloroplasts in the palisade mesophyll. This is because the palisade mesophyll is the primary site of photosynthesis in the plant, and chloroplasts are the organelles where photosynthesis occurs.
-
Spongy mesophyll cells are surrounded by air pockets to aid the diffusion of gases. These air pockets allow carbon dioxide to reach the photosynthesizing cells and oxygen to leave them.
-
Translocation is the movement of dissolved sugars around the plant through the phloem tissue. The phloem tissue is responsible for transporting the products of photosynthesis (sugars) from the leaves where they are produced to the other parts of the plant where they are needed.
-
Xylem transports water and minerals around the plant. The xylem tissue forms a continuous network of vessels and cells that constitutes the plant's water transport system from the roots, through the stem, and up to the leaves.
