Plant Parts – Root, Stem, Leaf, Transpiration, Respiration in Plants, Flower, Androecium, Gynoecium, Fruit, Transport Of Water And Minerals In Plants.
ROOT:
The main functions of the root system are absorption of water and minerals from the soil, providing a proper anchorage to the plant parts, storing reserve food material and synthesis of plant growth regulators.
In majority of the dicotyledonous plants, the direct elongation of the radicle leads to the formation of primary root which grows inside the soil. It bears lateral roots of several orders that are referred to as secondary, tertiary, etc. roots. The primary roots and its branches constitute the tap root system, as seen in the mustard plant
STEM:
The region of the stem where leaves are born are called nodes while internodes are the portions between two nodes.
Some stems perform the function of storage of food, support, protection and of vegetative propagation.
Underground stems of potato, ginger, turmeric, zaminkand, colocasia are modified to store food in them.
Stem tendrils which develop from axillary buds, are slender and spirally coiled and help plants to climb such as in gourds (cucumber, pumpkins, watermelon) and grapevines.
LEAF:
Leaves originate from shoot apical meristems. Leaf develops at the node and bears a bud in its axil. The axillary bud later develops into a branch.
A typical leaf consists of three main parts: leaf base, petiole and lamina.
The petiole help hold the blade to light. Long thin flexible petioles allow leaf blades to flutter in wind, thereby cooling the leaf and bringing fresh air to leaf surface.
Leaf Venation
The arrangement of veins and the veinlets in the lamina of leaf is termed as venation.
When the veinlets form a network, the venation is termed as reticulate. When the veins run parallel to each other within a lamina, the venation is termed as parallel.
Leaves of dicotyledonous plants generally possess reticulate venation, while parallel venation is the characteristic of most monocotyledons.

Plant Parts And Functions
1. Roots
1.1. The roots supports the plant and absorbs water and nutrients from the soil.
2. Stem
2.1. The stem supports the leaves and transfers water and nutrients to all parts of the plant.
3. Leaves
3.1. The leaves uses chlorophyll and sunlight to change carbon dioxide and water to sugar. It gives out oxygen and water.
4. Flower
4.1. The flower produces seeds. It is a reproductive part of the plant.
5. Fruit
5.1. The fruits disperses seeds and protects it.
6. Seed
6.1. The seed produces a new plant for the plant cycle to continue.
