Complete information on sexual reproduction in plants

Complete information on chemical Co-ordination in Plants
Plants produced certain chemical substances in their cells which regulate the growth of the plant body. These substances are formed in very minute quantities as a result of metabolic activities.
Complete information on the importance and process of Photosynthesis in plants
The term photosynthesis was first proposed by Barnes in 1898. The word has been derived from photo (light) and synthesis (building up). Photosynthesis is a process by which green plants are able to synthesize their food in the presence of sunlight and chlorophyll by taking carbon dioxide from the atmosphere and water from the soil.
Write a short note on transport of materials in Plants
Large organisms require a definite transport system. In most higher plants the transport system is made up to tube-like structures called xylem and phloem. These constitute a vascular system.
How do plants absorb water and minerals from the soil ?
Land plants absorb water from the soil mostly by root hairs. Root hairs are unicellular, thin-walled outgrowths of epidermis. They are in close contact with the thin film of water surrounding the soil particles.
How is water and minerals transported from the roots to upper parts of plants ?
The water and minerals absorbed by roots are conducted upwards to the leaves, flowers and other parts of the plant. It takes place through xylem tubes. The upward movement of sap that contains war and minerals is called ascent of sap.
Useful information on the excretion system in plants and animals
