Functions of a plant:
Functions of a plant:
Roots
Its primary functions are, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

Stem
The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.

Seed Dispersal
Seed Dispersal
Plant seeds can be dispersed in a number of different ways. Some seeds are transported by wind, and have seeds designed to float, glide or spin through the air.
Plants growing near a river may use the flowing water to transport their seeds.
Some seed pods are designed to explode and project the seeds a good distance from the parent plant.
Many plants also use animals to carry seeds around. These seeds may have handy hooks which attach to an animal’s fur. Alternatively, the plants might make tasty fruit to enclose the seeds, which attract animals to eat them.
