Hello guys !!!
Pls answer 5 th one !!!
*No irrelevant answers pls*

Dear students:
In plants, growth, development, and response to the environment is controlled and coordinated by a special class of chemical substances known as phytohormones. These hormones are produced in one part of the plant body and are translocated to other parts. For example, a hormone produced in the roots is translocated to other parts where they are required.

Thus, the growth hormones of plants are known as phytohormones. They are naturally occurring organic substances. They are synthesized in minute quantities in one part of the plant body and are translocated to other parts where they are required.

The plant hormones (or phytohormones) regulate many functions in plants. The various functions in plants which are regulated by the plant hormones (or phytohormones) are:
1. Germination of seeds (or Breaking the dormancy of seeds),
2. Growth of root, stem and leaves,
3. Movement of stomata (or stomatal movement) in leaves,
4. Flowering of plants,
5. Ripening of fruits, and
6. Phototropism, geotropism, chemotropism, hydrotropism, thigmotropism and nastic movements.
