Why Does Animals Have Chloroplasts
Once the sugar is made it is then broken down by the mitochondria to make energy for the cell.
Why does animals have chloroplasts. 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. The organelles are only found in plant cells and some protists such as algae. They can also obtain their food heterotrophically.
Animal cells use mitochondria to convert food into energy and plant cells use both chloroplasts and mitochondria to make energy from light air and water. Animal cells do not have chloroplasts. Chloroplasts are the food producers of the cell.
Because animals get sugar from the food they eat they do not need chloroplasts. They contain photosynthesizing chloroplasts within their cell which enable them to make their own food in sunlight just like plants. Nov 14 2015.
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. And vacuoles allow plant cells to change size.
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. 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. Why are chloroplasts located near the cell wall.
Some bacteria also perform photosynthesis but they do not have chloroplasts. In plants chloroplasts occur in all green tissues. While we do see some examples of animals that have chloroplasts and mitochondria in some of their cells such as in some sea slugs scientists wanted to see if they could make an animal that could photosynthesize.
