Why Does Animals Have Chloroplasts
Thats because animals are heterotrophic they cannot prepare their own food.
Why does animals have chloroplasts. The chloroplasts contain a green pigment called chlorophyll which captures the energy of sunlight for photosynthesis. Some bacteria perform photosynthesis but their chlorophyll is not relegated to an organelle. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to.
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. Animal cells do not have chloroplasts. Chloroplasts are organelles or small specialized bodies in plant cells that contain chlorophyll and help with the process of photosynthesis.
Once the sugar is made it is then broken down by the mitochondria to make energy for the cell. Like plant cells photosynthetic protists also have chloroplasts. So surely everyone else is.
They can simply use their chloroplasts to make their own glucose which they can then pass to the mitochondria to release chemical energy as and when it is required. Cyanobacteria are sometimes called blue-green algae even though they are prokaryotesThey are a diverse phylum of bacteria capable of carrying out photosynthesis and are gram-negative meaning that they have two cell membranesCyanobacteria also contain a peptidoglycan cell wall which is thicker than in other gram-negative bacteria. Mitochondria singular mitochondrion are often called the powerhouses or energy factories of a cell because they are responsible for making adenosine triphosphate ATP the cells main energy-carrying moleculeThe formation of ATP from the breakdown of glucose is known as cellular respiration.
Both animal and plant cells have mitochondria but only plant cells have chloroplasts. Organisms having chloroplasts are the ancestors of those having acquired such through the evolutionary process of endosymbiosis where smaller cells with the capacity for photosynthesis took up residence within larger cells in mutual symbiosi. They can also obtain their food heterotrophically.
Plant Cells Chloroplasts and Cell Walls. Animal cells dont have chloroplasts because animals arent green plants. Cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves.
