Why Does Animals 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.
Why does animals have chloroplasts. The chloroplasts contain a green pigment called chlorophyll which captures the light energy that drives the reactions of photosynthesis. Why are chloroplasts located near the cell wall. Animal cells dont have chloroplasts because animals arent green plants.
Nov 14 2015. Chloroplasts are the food producers of the cell. Some bacteria perform photosynthesis but their chlorophyll is not relegated to an organelle.
Both animal and plant cells have mitochondria but only plant cells have chloroplasts. Cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves. Chloroplasts are a type of plastid that are distinguished by their green color the result of specialized chlorophyll pigments.
Thats because animals are heterotrophic they cannot prepare their own food. 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. And vacuoles allow plant cells to change size.
Plants dont get their sugar from eating food so they need to make sugar from sunlight. 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.
Once the sugar is made it is then broken down by the mitochondria to make energy for the cell. Animal cells do not have chloroplasts. Chloroplasts are found only in plants and photosynthetic algae.
