What is a chloroplast? Explain how a root of a plant, that lacks Chloroplasts, gets energy. What organelles are involved with converting the energy for the roots?
in 5 sentences explain
A chloroplast is an organelle found in plant cells that is responsible for the process of photosynthesis. It contains chlorophyll, a pigment that absorbs light energy from the sun, and uses this energy to convert carbon dioxide and water into glucose and oxygen.
Roots of plants that lack chloroplasts, such as underground roots, obtain energy through a process called respiration. This involves the breakdown of stored glucose molecules in the presence of oxygen, producing energy in the form of adenosine triphosphate (ATP).
The organelles involved in converting energy for the roots are mitochondria. Mitochondria are present in all eukaryotic cells, including plants, and are responsible for aerobic respiration. They take in oxygen and glucose, and through a series of chemical reactions, release energy in the form of ATP.
In the absence of light and chloroplasts, the roots rely solely on the stored glucose produced by the leaves or other photosynthetic organs of the plant. This glucose is transported to the roots through the vascular system and is then broken down by the mitochondria to release energy for various cellular processes in the root cells.
