How do mitochondria differ from 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.
How do mitochondria and chloroplasts differ from other organelles in eukaryotic cells?
Mitochondria and chloroplast are semiautonomous organelles that share various structural similarities but the major difference is their occurrence. Mitochondria are found in eukaryotic animal cells, whereas chloroplasts are found in plant cells.
What is one similarity and one difference between chloroplasts and mitochondria?
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.
How are mitochondria and chloroplasts similar in terms of the Endosymbiotic theory )?
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.
What about the mitochondria and chloroplast is unlike any other organelle?
Unlike any other organelle, except for chloroplasts, mitochondria appear to originate only from other mitochondria. They contain their own DNA, which is circular as is true with bacteria, along with their own transcriptional and translational machinery.
What is the difference between mitochondria and mitochondria?
The only difference between mitochondria and mitochondrion is that mitochondrion is singular, and mitochondria is the plural form of the word.
What is characteristics of both mitochondria and chloroplasts?
Even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells. These prokaryotic cell characteristics include: an enclosed double membrane, circular DNA, and bacteria-like ribosomes.
How are mitochondria part of endosymbiotic theory?
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.
How do chloroplasts differ from mitochondria quizlet?
Which of the following explains how chloroplasts differ from mitochondria? -In chloroplasts, the proton gradient is generated between the thylakoid lumen and the stroma. -Only mitochondria have a double membrane. -Only the mitochondrion has DNA, RNA, and ribosomes.
What is the main difference between mitochondria and chloroplasts quizlet?
what is the difference between mitochondria and chloroplasts? Mitochondria are oxidative metabolic bacteria derivatives and chloroplasts are photosynthetic bacteria derivatives.
Why are mitochondria and chloroplasts considered endosymbionts?
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
How are the mitochondria and chloroplast similar quizlet?
Mitochondria and chloroplasts are similar to one another in that: a) both convert the energy of the sugar into ATP for use by the cell. b) both capture the energy of the sun during photosynthesis and store it as sugar. c) both are present in all eukaryotic cells.
How are chloroplasts like mitochondria quizlet?
How are mitochondria like chloroplasts? They have the same structure. They both absorb the energy of the sun. They are both concerned with energy.
Why is the mitochondria considered an endosymbiont?
Mitochondria are regarded as organelles rather than endosymbionts because mitochondria and the host cells share some parts of their genome, undergo mitosis simultaneously, and provide each other means to produce energy.
Why mitochondria is called as power house of cell how it differs from chloroplast?
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.
How are mitochondria similar to chloroplasts?
Both chloroplasts and mitochondria are semi-autonomous organelles having their own DNA and protein-synthesizing mechanisms. Both of them help in the cytoplasmic inheritance of certain specific characters and both depend on nuclear genes for biosynthetic activities.
Why mitochondria is known as the powerhouse of the cell?
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
How are mitochondria and chloroplasts similar?
Chloroplasts and mitochondria both are membrane-bound organelles which are involved in energy conversion. Chloroplast stores light energy in the chemical bonds of glucose in the process called as photosynthesis.
What is the shape of mitochondria?
Mitochondria have a double-layered membrane. They are rod-shaped or sausage-shaped organelles measuring 0.5-10μm in length. In a typical cell, it occupies almost 25% of the cell volume. Earlier mitochondria were represented as individual isolated organelles, now they form a dynamic connected network also called a reticulum.
What is the function of the multi-compartment structure of mitochondria?
The multi-compartment structure of the mitochondrion may seem complicated to us. That’s true, but it turns out to be very useful for cellular respiration, allowing reactions to be kept separate and different concentrations of molecules to be maintained in different “rooms.”
Where does mitochondrial DNA reside in the cell?
The mitochondrial DNA resides in its matrix. Also, it is small and circular. Mitochondria are essential for aerobic metabolism. They are responsible for energy production through oxidative phosphorylation. Almost 90% of the cell’s energy is produced by them.
