Which best describes a difference between prokaryotes and eukaryotes?

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

What is the main difference between prokaryotes and eukaryotes?

Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.

What are 3 differences between prokaryotic and eukaryotic cells?

What is the main function of ribosome?

Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).

What are the two main function of ribosomes?

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.

What is the main function of endoplasmic reticulum?

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

What are the two main functions of endoplasmic reticulum?

Endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins .

What are the three forms of endoplasmic reticulum?

Endoplasmic reticulum can exist in three forms (Fig. 8.

What is the function of endoplasmic reticulum Class 8?

Endoplasmic reticulum performs the following functions: It is responsible for the production and secretion of steroid hormones. It is also responsible for the synthesis of essential lipids such as phospholipids and cholesterol. It is responsible for the metabolism of carbohydrates.

What is RER and SER?

Quick look. Rough ER (RER) is involved in some protein production, protein folding, quality control and despatch. It is called 'rough' because it is studded with ribosomes. Smooth E R (SER) is associated with the production and metabolism of fats and steroid hormones.

Why are RER membrane is rough in nature?

RER or Rough Endoplasmic Reticulum is rough in nature due to the presence of ribosomes, which are attached to its surface. Endoplasmic reticulum can be of two forms- the rough endoplasmic reticulum( RER) and the smooth endoplasmic reticulum( SER).

What is difference between rough and smooth endoplasmic reticulum?

Smooth Endoplasmic Reticulum does not have ribosomes on its membrane. Rough Endoplasmic Reticulum possesses ribosomes attached to its membrane. It is organized of vesicles and tubules.

What type of proteins are synthesized by the rough ER?

The rough endoplasmic reticulum plays a number of roles within the cell, largely associated with protein synthesis. Polypeptides are synthesized, modified, folded into their correct 3-D shape and sorted towards an organelle or marked for secretion.

What is rough ER in biology?

Rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.

What is the main function of cytoplasm in a cell?

What is the important function of cytoplasm? The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.

What are the two types of endoplasmic reticulum and what are their functions?

There are two types: rough and smooth. Smooth endoplasmic reticulum is where lipid synthesis occurs, and where the organelle handles toxic substances within the cell. Rough endoplasmic reticulum is named for its rough appearance due to ribosomes attached to its folds. This is where most protein synthesis occurs.
