Why Does Animals Have Chloroplasts
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.
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. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to. 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.
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. Species of Euglena have characteristics of both plants and animals. Why are chloroplasts located near the cell wall.
Cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves. The chloroplasts contain a green pigment called chlorophyll which captures the energy of sunlight for photosynthesis. They contain photosynthesizing chloroplasts within their cell which enable them to make their own food in sunlight just like plants.
Like plant cells photosynthetic protists also have chloroplasts. Chloroplasts are considered endosymbiotic Cyanobacteria. Chloroplasts are found only in plants and photosynthetic algae.
Both animal and plant cells have mitochondria but only plant cells have chloroplasts. Some bacteria perform photosynthesis but their chlorophyll is not relegated to an organelle. This process photosynthesis takes place in the chloroplast.
Some bacteria also perform photosynthesis but they do not have chloroplasts. They directly or indirectly depend on plant for food. Mitochondria and Chloroplasts Mitochondria.
