Why Does Animals Have Chloroplasts
Plant Cells Chloroplasts and Cell Walls.
Why does animals have chloroplasts. They can also obtain their food heterotrophically. And vacuoles allow plant cells to change size. This process photosynthesis takes place in the chloroplast.
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. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
Chloroplasts are organelles or small specialized bodies in plant cells that contain chlorophyll and help with the process of photosynthesis. 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 directly or indirectly depend on plant for food. Humans and other animals do not have chloroplasts The chloroplasts job is to carry out a process called photosynthesis. Like mitochondria chloroplasts have their own DNA.
Because animals get sugar from the food they eat they do not need chloroplasts. In plants chloroplasts occur in all green tissues. Chloroplasts are considered endosymbiotic Cyanobacteria.
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. Some bacteria perform photosynthesis but their chlorophyll is not relegated to an organelle. So surely everyone else is.
