What do mitochondria have that other organelles lack?

What do mitochondria have that other organelles lack?

Mitochondria are unlike other cellular organelles in that they have two distinct membranes and a unique genome and reproduce by binary fission; these features indicate that mitochondria share an evolutionary past with prokaryotes (single-celled organisms).

How are chloroplasts and mitochondria different from the other organelles?

Mitochondria are the “powerhouses” of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis.

What do mitochondria and chloroplasts not have in common?

Importantly, the DNA in mitochondria and chloroplasts is not the same as the DNA in the nucleus, and the DNA in the mitochondria and chloroplasts is circular in shape, which is also the shape of DNA in prokaryotes (single-celled organisms without a nucleus).

What do mitochondria and chloroplasts have?

Chloroplasts synthesize organic compounds whereas mitochondria produce most of the cytoplasmic ATP. Both organells are covered with two membranes and contain circular DNA and ribosomes similar to bacterial. Chloroplasts have thylakoids, or inner membrane pockets and vesicles.

Why does bacterial cell not have mitochondria?

Prokaryotes, on the other hand, are single-celled organisms such as bacteria and archaea. Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus; instead their genetic material is free-floating within the cell. Thus, prokaryotes have no mitochondria.

Why do plants need both chloroplasts and mitochondria?

Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.

Why mitochondria and chloroplasts are not considered in the Endomembrane system?

The functions of the mitochondria, chloroplasts and peroxisomes are not coordinated with the endoplasmic reticulum, Golgi complex, lysosomes and vacuoles. Hence, they are not part of the endomembrane system.

Why mitochondria and chloroplasts are similar to a bacterial cell?

Chloroplasts and mitochondria have their own ribosomes that are similar to those of bacteria and unlike those of the rest of the cell. For this reason, they are sensitive to antibiotics that kill bacteria by binding to and inactivating bacterial ribosomes.

What are two common characteristics of mitochondria and chloroplasts?

Both organelles are involved in energy transformation, mitochondria in cellular respiration and chloroplasts in photosynthesis. They both have multiple membranes that separate their interiors into compartments.

Why are chloroplasts and mitochondria similar?

Like mitochondria, chloroplasts contain their own genetic system, reflecting their evolutionary origins from photosynthetic bacteria. The genomes of chloroplasts are similar to those of mitochondria in that they consist of circular DNA molecules present in multiple copies per organelle.

Which of the following describes characteristics of both mitochondria and chloroplasts?

Do bacteria have mitochondria and chloroplasts?

Mitochondria, which provide energy for the cell, are one of these membrane-bound structures called organelles. Chloroplasts are organelles in plant cells that can make food. These two organelles have much in common with bacteria and may actually have evolved directly from them.

How are chloroplasts and mitochondria related to each other?

Key points: Mitochondria are the “powerhouses” of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis.

Which is cell organelles consists of chloroplast?

Chloroplasts, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division.

Which is part of the mitochondria has its own DNA?

Mitochondria are oval-shaped, double-membrane organelles ( Figure 1) that have their own ribosomes and DNA. Each membrane is a phospholipid bilayer embedded with proteins. The inner layer has folds called cristae, which increase the surface area of the inner membrane.

Where are chloroplasts found in a plant?

Chloroplasts are organelles found in the broccoli’s cells, along with those of other plants and algae. 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.
