why do mitochondria and chloroplasts have their own dna?
325280
According to the endosymbiosis theory, Mitochondria and chloroplasts were once organisms (bacteria) of their own that got engulfed by another cell and somehow engaged in a symbyiotic (mutualistic) relationship with each other. That is why they have DNA, because they were once distinct organisms.

Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function.

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. ... Mitochondria generate ATP from glucose during cellular respiration, chloroplasts generate ATP from light to create glucose for storage. The space within mitochontria is called matrix, the same thing in chloroplasts is called stroma.

They capture light energy and store it as fuel molecules in the plant's tissues. Mitochondria are found inside of your cells, along with the cells of plants. They convert the energy stored in molecules from the broccoli (or other fuel molecules) into a form the cell can use.

Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both. Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients. Chloroplast is the site for photosynthesis in a plant cell.

This pigment helps the cells to prepare its own food by the process of photosynthesis. So thats why Chloroplast is the cell organelle which is known as Kitchen of the cell.

Yes, their are cells in human which prokaryotic in origin like mitochondria. In plants chloroplast like cells are prokaryotic in origin. As both have 70s type of ribosomes and typically divide in prokaryotic fashion.

Mitochondria and Chloroplasts Mitochondria within animal cells and chloroplasts within plant cells look like prokaryotes. ... Chloroplasts, like mitochondria, produce energy for plant cells. Both mitochondria and chloroplasts have their own circular DNA and can function independently of the eukaryotic host cell.

2. DNA is Circular in Shape. Another similarity is that both mitochondria and chloroplasts contain some amount of DNA (though most DNA is found in the cell's nucleus). ... The DNA in the nucleus of a eukaryote is coiled up in the form of chromosomes.

Why are mitochondria and chloroplasts believed to have entered early eukaryotic cells by endosymbiosis of bacteria? They are the same size as bacteria. They contain DNA. They are not derived from the endomembrane system as other organelles are.

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. ... Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

Mitochondria and chloroplast are semiautonomous organelles that have single-stranded circular DNA. The ribosome is an assemblage of ribosomal RNA and ribosomal protein but does not contain its own DNA. Thus, the correct answer is option D.

Mitochondria are responsible for cellular respiration and energy metabolism. Conversely, Chloroplast is found only in green plants and in few algae, they are the sites of photosynthesis. This organelle of the cell is much more complex and larger than the mitochondria.

1 Answer. (i) (a) Both are double membrane structures. (b) Both of them have their own genetic material. (ii) Mitochondria is the site of production of energy whereas plastid is the site of production of food.

How did mitochondria and chloroplasts most likely arise? They arose from bacteria that were engulfed and not digested. Mitochondria are thought to have arisen from aerobic bacteria, and chloroplasts from photosynthetic bacteria. This explains their double membrane and own chromosomes.

Mitochondria is a semi autonomous body as it contains its own DNA and nucleus. The inner membrane of mitochondria will also contain ribosomes which is why it can synthesize its own protiens.

Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an inner and an outer membrane.
