Question

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

Answer 1

Answer:

All the options are correct,

however in case of choosing just one option, I recommend the first one (i).

Explanation:

Plants require water as raw material in the process of photosynthesis to prepare food (in the form of glucose).

i.e.

6CO2 (carbon dioxide) + 6H2O (water) -------> C6H12O6 (glucose)

Answer 2

Answer:

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.
