Heya.
Here's your answer..
Role of -
> AUXINS = 1- They promote cell enlargement and cell differentiation in plants.
2- they also promote stem and fruit growth.
3-there regulate important plant growth movements i.e. - tropisms
4- these induce parthenocarpy in number of plants.
Role of -
> CYTOKININS-
1- they promote cell division in plants.
2- they help in Breaking the dormancy of seeds and buds.
3- they delay the aging in leaves.
4- they promote the opening of stomata.
5- they also promote fruit growth.
HOPE IT HELPS YOU ☺

Role of auxins:
- Inhibit the growth of Lateral Buds which helps in maintaining the apical dominance.
- Auxin helps in the cell elongation. It mainly helps to elongate the growth of stem.
- Auxins are produced inside the cell of Seeds, Fruits, root, bud and stem.
- Auxin enlarge the growth of the cell which later moves to the darker side of the plant to grow larger than the corresponding cell to it.
- This helps plants to make their stem tip curved.
- Auxin also promotes in the development and propose of Fruit. Because of which, proper fruits are formed on the plants.
- As we know that, Auxin is a type of "Chemotropic movement". Which shows the growth of the plant towards the external stimulus Sunlight.
- Auxin at the tip of the stem absorbs the sunlight and by the process of diffusion, the growth of plant occurs.
- This happens due to the differences in concentration.
Auxin: Auxin is a growth hormone which is mainly found at the tip of the stem. Auxin helps in the growth and development of the stem. Auxin is a type of chemical from "Chemotropic Movement". This type of movement shows the growth and development towards the external stimulus sunlight.
