How are mitochondria and chloroplasts similar to bacteria?

Replication. Mitochondria and chloroplasts make more of themselves in much the same way as bacteria reproduce. Like bacteria, mitochondria and chloroplasts grow in size, duplicate their DNA and other structures, and then divide into two identical organelles.

What are two things that mitochondria and chloroplasts have in common with bacteria?

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.

What do mitochondria and bacteria have in common?

Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria’s genome, but much smaller.

How are chloroplasts similar to bacteria?

– Chloroplasts and mitochondria are prokaryotic. They have their own genes on a small, circular chromosome but no nucleus. This chromosome has little non-coding DNA, similar to those of bacteria. Chloroplasts and mitochondria also make some of their own proteins from their genes.

What are the similarities and differences between mitochondria and chloroplast?

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.

What is the relationship between mitochondria and chloroplasts?

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.

What do mitochondria and eukaryotic cells have in common?

All membranous eukaryotic cell organelles have the common feature of a phospholipid bilayer, although the proteins differ in each case. Mitochondria are large organelles containing DNA and surrounded by a double membrane. The inner membrane is highly convoluted, with deep folds called cristae.

What do mitochondria and Thylakoid have in common?

The mitochondrial membrane and thylakoids membranes have a couple things in common: Both membranes contain ATP Synthase Proteins.

What similarities do you notice between the mitochondria and the bacteria?

Mitochondria are located in the cytoplasm of both animal and plant cells; they are cylindrical structures that consist of an outer membrane, inner membrane and matrix. Like bacteria, mitochondria also have their own circular DNA genome which is separate from the nucleus of the cell which is located in the matrix.

What bacteria did mitochondria come from?

The endosymbiotic hypothesis for the origin of mitochondria (and chloroplasts) suggests that mitochondria are descended from specialized bacteria (probably purple nonsulfur bacteria) that somehow survived endocytosis by another species of prokaryote or some other cell type, and became incorporated into the cytoplasm.

Do bacteria have chloroplasts?

Bacteria do not have chloroplast, but some bacteria are photoautotrophic in nature and performs photosynthesis.

Can bacteria be killed by antibiotics?

Antibiotics do kill specific bacteria. Some viruses cause symptoms that resemble bacterial infections, and some bacteria can cause symptoms that resemble viral infections. Your healthcare provider can determine what type of illness you have and recommend the proper type of treatment.

How are mitochondria and chloroplasts related to each other?

We also know that mitochondria and chloroplasts have DNA and ribosomes, just as bacteria do. Scientists believe that host cells and bacteria formed a mutually beneficial endosymbiotic relationship when the host cells ingested aerobic bacteria and cyanobacteria but did not destroy them.

How are mitochondria and chloroplasts sensitive to antibiotics?

Both mitochondria and chloroplasts are sensitive to antibiotics which affect bacteria such as streptomycin, spectinomycin, neomycin, and chloramphenicol while they are unaffected by agents such as cyclohexamide that affect the cytoplasm.

Where are chloroplasts found in the eukaryotic cell?

Chloroplasts function in photosynthesis and can be found in eukaryotic cells such as plants and algae. Carbon dioxide (CO 2 ), water, and light energy are used to make glucose and oxygen in photosynthesis.

How many genes are in the mitochondria of a bacterium?

  Even bacterium Rickettsiaprowazekii, which is an intracellular parasite which has a reduced genome with only 834 genes.   The genome size of mitochondria varies from 60 to 200 genes in different organisms (Berry, 2003).
