Can plastids produce protein?
Chloroplasts fulfill important functions in cellular metabolism. The majority of plastid genome-encoded genes is involved in either photosynthesis or chloroplast gene expression. We demonstrate here an essential role of plastid protein synthesis in tobacco leaf development.
Is it able to make their own protein?
The presence of translational machinery in mitochondria allows it to make its own proteins. Complete answer: Mitochondria can make some of the protein because they possess ribosomes as well as genetic instructions for manufacturing proteins.
What is the importance of plastids?
Plastids provide essential metabolic and signaling functions, such as the photosynthetic process in chloroplasts. However, the role of plastids is not limited to production of metabolites.
How do plastids work in the photosynthetic process?
In land plants, plastids that contain chlorophyll can carry out photosynthesis and are called chloroplasts. Plastids can also store products like starch and can synthesize fatty acids and terpenes, which can be used for producing energy and as raw material for the synthesis of other molecules.
Why mitochondria and plastids are able to synthesise some of their own proteins?
Explanation: Mitochondria and plastids can synthesis some of their own protein, the reason is they have their own specialized ribosomes and DNA. The protein formation is supported by the ATP present in this organelle.
Why mitochondria is able to make its own protein?
Mitochondria is able to make some of the protein because the mitochondria contains ribosomes (protein factories of the cell) within. They are the organelles containing the nucleic acid and ribosomes within facilitating the production of mitochondrial DNA and mitochondrial proteins.
What are plastids and its function?
Plastids are double-membrane organelles which are found in the cells of plants and algae. Plastids are responsible for manufacturing and storing of food. These often contain pigments that are used in photosynthesis and different types of pigments that can change the colour of the cell.
What is the function of plastids in the cell?
Plastids are responsible for photosynthesis, storage of products like starch, and for the synthesis of many classes of molecules such as fatty acids and terpenes, which are needed as cellular building blocks and/or for the function of the plant.
Which cell organelle is capable of making their own proteins?
Ribosomes, large complexes of protein and ribonucleic acid (RNA), are the cellular organelles responsible for protein synthesis. They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA).
How is this organelle able to make its own proteins?
organelle able to make its own proteins? Mitochondria is the organelle where aerobic respiration and ATP synthesis takes place. Many of the proteins inside the mitochondria are coded by its own genome and are synthesised using the ribosomes present inside it.
