With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids.
The correct answer is option (D) A sandwich is digested and converted to carbon dioxide and water.
Digestion is a catabolic process of breakdown of complex food substances into simpler nutrients releasing energy. In the process of digestion of a sandwich, the carbohydrates are broken down into simpler sugars in presence of enzymes releasing water, carbon dioxide and energy in the form of adenosine triphosphate (ATP). This ATP is the reserved energy currency and also used for the growth, repair and replacement of cells.
Answer:
1. Flower-The biological function of a flower is to affect reproduction, usually by providing a mechanism for the union of sperm with eggs.
2. leave-Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food
3. Stem-The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots
4. Roots-Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels ( xylem )
