VEGETATIVE PARTS OF PLANTS
Roots, stems and leaves are vegetative organs of plants that could be used for asexual reproduction. This means that they do not produce sex cells or play a direct role in sexual reproduction. Nevertheless, these organs play an important role in the life cycle of plants.
Roots
The roots anchor the plants and hold the stem upward. They also absorb water and nutrients from the soil, which are then passed on to the stem and leaves.
There are different types of root system like the fibrous root system that consists of numerous, long, slender lateral roots, typically of monocots, and the taproot system that has a well developed primary root that has other smaller lateral roots, typically of dicot plants.
Other roots that arise from stems and leaves are called adventious roots.

Stem
It is the organ of the plant that supports the leaves and flowers in the best position. It is the passageway of nutrients from the soil to the different parts of the plant. The stem is very important to man. Lumber for our houses comes from this part of the plant. It has nodes, internodes and lenticels that serve for gas exchange.

Leaf
A leaf is a flattened, green, lateral appendage that carries out the functions of photosynthesis and transpiration. It is responsible for taking in carbon dioxide and releasing oxygen and water vapor. Gases pass through small openings found on the leaf called stomata. Chlorophyll gives the leaf its green color. Other structures traversing the blade of the leaf are the veins. These are responsible for the distribution of food to the different parts of the plant. They are connected to the stem by means of the petiole at the nodes of the stem.
