Plants and fungi are usually filamentous to increase the surface area in which they uptake their food, and this is advantageous as they raise their surface area for sunlight in photosynthesis.
Conversely, animals are usually round to reduce surface area for loss of water and heat. Unlike plant and fungi, most of their food intake is through the mouth hence not affected by surface area.
Leaves wilt.
Growth is slow.
Brown spots appear on leaf tips.
New and older leaves eventually turn yellow and fall at the same time.
Soil is constantly damp or drainage is too slow.
Roots become spongy, turn brown and rot.
Tubes for Transporting Food-carrying tubes Phloem Water-carrying tubes Xylem Sugar is produced In the leaves. The food-carrying tubes transport this sugar from the leaves to the other parts of the plant. The root hairs found on the roots Take in water and mineral salts from the soil.
