8. a) describe how water is important to plants in terms of:
i) making food in plants
ii) the plant's shape
iii) hydrolysis and dehydration

All options are correct.

Explanation:

    1. Making food in plants:

All plants need water, light and carbon dioxide to make food, plants can make their own food by using these mentioned things.The food making process in plants called photosynthesis.Chlorophyll helps plants to make food and gets its green color by using water and sun energy.  

    2. The plant's shape:

Water is the main element that help plant to make its structure.Water is essential for plant to receive nutrients and provide for itself.Most of the plants get there shape by the pressure of the water present in their cells.

  3. Hydrolysis and dehydration:

Dehydration synthesis keep monomers together to form a polymer, water is removed by taking hydrogen from one molecule and an alcohol from the other molecule.Hydrolysis stands for break with water, polymer breakdown back into monomers.
