What is the difference between Chloroplast and Mitochondria? Chloroplasts are found in plant and algal cells. Mitochondria are found in. The major difference between chloroplasts and mitochondria, in terms of both structure and.
The mitochondrial DNA is located inside the mitochondria, which are cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use. The mitochondrial DNA is passed down directly from the mother and the genes are specific to the mother's lineage.
It is passed down from mothers to sons and daughters. Sons cannot pass along their mothers' mtDNA to their children. This happens because mtDNA is transmitted through the female egg. In sexual reproduction, mitochondria are normally inherited exclusively from the mother. The mitochondria in mammalian sperm are usually destroyed by the egg cell after fertilization.
Difference Between Chloroplast and Mitochondria | Structure, Function, Comparison
The fact that mitochondrial DNA is maternally inherited enables researchers to trace maternal lineage far back in time. Chloroplast Function and Structure Chloroplasts are very similar to mitochondria, but are found only in the cells of plants and some algae. Like mitochondria, chloroplasts produce food for their cells. Chloroplasts help turn sunlight into food that can be used by the cell, a process known as photosynthesis. Like the mitochondria, the chloroplast has an inner and outer membrane.
Inside those membranes are its different parts, which include thylakoids and stroma. A stack of thylakoids is called a grana pl.
Chlorophyll molecules on the thylakoids capture sunlight and begin the process of photosynthesis. What Are the Five Parts of the Chloroplast? Two membranes contain and protect the inner parts of the chloroplast.
These membranes are named the outer and inner membranes. The inner membrane surrounds the stroma and the grana stacks of thylakoids. One thylakoid stack is called a granum. Parts of the Chloroplast What It Does Inner membrane The inner membrane is less permeable and studded with transport proteins.
The innermost matrix of chloroplasts, called the stroma, contains metabolic enzymes and multiple copies of the chloroplast genome. Outer membrane The outer membrane provides further protection to the chloroplast. Stroma Stroma refers to the colorless fluid surrounding the grana within the chloroplast. Thylakoids A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis.
Granum Stacked into grana, the shape of the thylakoids allow for optimum surface area, maximizing the amount of photosynthesis that can happen.
Compare and Contrast: Chloroplasts and Mitochondria
Where Is the Chloroplast Located in a Cell? The chloroplast is located throughout the cytoplasm of the cells of plant leaves and other parts depending on the type of plant. You can see where the chloroplasts are because chloroplasts they are what make the plant appear green.
Therefore, wherever there is green on a plant there are chloroplasts. Chlorophyll is found in the chloroplasts of plants. Chlorophyll absorbs light in the red long wavelength and the blue short wavelength regions of the visible light spectrum.
Green light is not absorbed but reflected. This is the reason, that why mitochondria contain its own DNA, and shows similarity with the prokaryotic cell bacteria. Though cellular respiration is not a simple process, the process involves three main steps: Further, the ATP released from the mitochondria is used by the other organelles, present in the cell.
Definition of Chloroplast As said above, chloroplast is one of the double-membrane organelles of the cell. These are found in green plants and green algae. The chloroplast is the site of photosynthesis, having their genome. These are the complexed structure, having the size of around 10um and 0. The structure of the chloroplast has the rigid cell wall, most importantly it contains thylakoids, which is the flat disc shape structure.
Numerous thylakoids, which makes the bundle known as grana. These grana are present in the central area of the stroma. Another important part is chlorophyll, which is a green pigment and plays its role in capturing the sunlight, this is also present in thylakoid.
Difference Between Mitochondria and Chloroplast
The thylakoid membrane also contains enzymes and other light-absorbing pigments, that are used in producing energy in the form of ATP adenosine triphosphate. Key Differences Between Mitochondria and Chloroplast Following are the key difference between the two most important organelles of the cell: 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. Mitochondria are present in the cells of all types of aerobic organisms like plants and animals, whereas Chloroplast is present in green plants and some algae, protists like Euglena. Mitochondria is the colourless, bean shape organelles. Chloroplasts are green colour and disc shape organelles.
Mitochondria and Chloroplast have two chambers inside them which is the matrix and the cristae in mitochondria, stroma, and thylakoids in a chloroplast. The inner membrane of mitochondria is folded into cristae while that of a chloroplast, rises into flattened sacs called as thylakoids. The thylakoid membrane in chloroplast contains carotenoids, chlorophyll, and photosynthetic pigments, but these are absent in mitochondria.
Mitochondria convert sugar glucose into chemical energy called as ATP adenosine triphosphateit uses oxygen and release energy by breaking the organic food and in turn produces carbon dioxide along with water. In chloroplast the solar energy is stored, this organelle helps in storing the energy, further it also uses carbon dioxide and water to make glucose. Chloroplast liberates or releases oxygen. Similarities Both are double membrane structure. They both provide energy to the cell.
Both the organelles contain enzyme and coenzyme.
There is the involvement of the oxygen and carbon dioxide. Another unique feature is that both the organelles can move from one place to another within the cell.
