To give plants rigidity is NOT a way that fats are used in living things.
To give plants rigidity is NOT a way that fats are used in living things. To determine the correct answer, we can evaluate each option:
1. As chemical messengers: Fats, specifically lipids known as hormones, can act as chemical messengers in the body, helping to regulate various physiological processes. Therefore, this is a valid way fats are used in living things.
2. To store energy: Fats play a crucial role in energy storage. They are stored in specialized cells called adipocytes and can be broken down to provide a long-term source of energy when needed. Thus, this is a correct way fats are used in living things.
3. As parts of biological membranes: Fats, particularly phospholipids, are essential components of biological membranes. They form a lipid bilayer that helps maintain the structure and fluidity of cell membranes. Hence, this is a valid way fats are used in living things.
4. To give plants rigidity: This option is incorrect. Fats are not involved in providing rigidity to plants. Instead, plant cell walls, primarily made of cellulose, provide rigidity and support to plant cells.
Therefore, the correct answer is: To give plants rigidity.
