Are ribosomes found in vacuoles?
D) Inside the vacuole. Hint:Ribosomes are cell organelles which play an important role in the mechanism for protein synthesis.
What is the function of the vacuole?
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
What is the function of ribosome?
A ribosome functions as a micro-machine for making proteins. Ribosomes are composed of special proteins and nucleic acids. The TRANSLATION of information and the Linking of AMINO ACIDS are at the heart of the protein production process.
Which is a primary function of a vacuole in a cell?
Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.
What is the function and structure of ribosomes?
The main function of ribosomes is to serve as the site of mRNA translation ( = protein synthesis, the assembly of amino acids into proteins); once the two (large and small) subunits are joined by the mRNA from the nucleus, the ribosome translates the mRNA into a specific sequence of amino acids, or a polypeptide chain.
What is the function of central vacuole in plant?
Among its roles in plant cell function, the central vacuole stores salts, minerals, nutrients, proteins, pigments, helps in plant growth, and plays an important structural role for the plant.
What is the function of the contractile vacuole?
The contractile vacuole (CV) complex is an osmoregulatory organelle of free-living amoebae and protozoa, which controls the intracellular water balance by accumulating and expelling excess water out of the cell, allowing cells to survive under hypotonic stress as in pond water.
What is the function of a vacuole in a cell?
Vacuole is mostly defined as a storage bubble which is found in cells. These vacuoles might store food or any variety of nutrients a cell might need to survive, not only this but vacuoles can even store waste products so that the rest of the cell is protected from contamination.
What is the function of the ribosome in the cell?
Ribosomes are the organelles that help in protein synthesis. Protein is required for many cell activities such as damage repair and other chemical processes. What is a ribosome composed of? A ribosome is composed of two subunits:
Why do vacuoles have different properties in different organisms?
In each organism, different genetics cause different proteins to be embedded in the membrane of the vacuole, which allow different molecules through, and gives the vacuoles different properties. Most plant cells have evolved to use vacuoles as water storage organelles, which provide a variety of functions to the cell.
How big are vacuoles in plant and animal cells?
The vacuoles in plant cells are larger than those in the animal cells. The plant vacuoles occupy more than 80% of the volume of the cell. The vacuoles may be one or more in number. Let us have a detailed look at the structure and function of vacuoles.
