What is the role of fats in fruits and seeds of plants?

Fats are widely distributed in plant organisms. They are in absolutely every plant cell. Plants accumulate fatty oils: in seeds (sunflower, corn, flax) and fruits (sea buckthorn, olive). Their concentration is within 2 – 70%, and there is an indicator even higher. Seeds contain fats in the cells of the parenchymal tissue of the endosperm. In a plant, living fats are of a liquid consistency.
Role of fats: Fats are a form of storage nutrients that are valuable as a source of energy. 1 g of fat is a source of 9.5 kcal. Comparison: 1 g of protein provides 4.4 kcal when used, and carbohydrates – 4.2 kcal. Fats are a reserve material during the period of seed germination and the next development of the embryo. Fats are protective substances when exposed to low temperatures.
