In general the three main components to a plant are the root system, the shoot system, and the leaves. In general the roots collect nutrients and the shoot collects carbon dioxide. Working together these systems allow for plant growth to exist under multiple conditions.
Most roots have a section called a taproot and a lateral roots which are analogous to the tributaries of a river. The roots help to hold a plant in the soil while preventing soil erosion. It is also common for the roots to make up most of a plants mass and streach for large distances underground. In many places the roots of a plant will allow a plant to reappear after a situation such as a fire. Roots may also act as a place for plants to store food such as starch.
The shoot is made up of one or more stems. It is here that most nutrient/water transport may occur in the plant. They may range in size and have diffent light-gathering features. There is also variation in the shape of the plant as this may give an advantage to a plant when it is competing for light. Roots my also provide additional structural support under different conditions. They may roots may also assist the shoot system with gas exchange.
