Is endoplasmic reticulum ER found in plant or animal cells?

Is endoplasmic reticulum ER found in plant or animal cells?

Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER.

What is the ER in a cell?

The endoplasmic reticulum (ER) is the largest membrane-bound organelle in eukaryotic cells and performs a variety of essential cellular functions, including protein synthesis and processing, lipid synthesis, and calcium (Ca2+) storage and release.

What types of cells is the rough ER found in?

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 rough ER in a cell?

= Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.

Why is the ER considered the circulatory system of the cell?

Answer: The endoplasmic reticulum help in transportation of protein from different part of the cell. The function ER is related to the circulatory system of the body because they are responsible for both transportation of needed material in the body or cell.

What is the main function of ER?

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. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

What cell is most like the circulatory system?

The endoplasmic reticulum transports materials from one part of the cell to another, like the circulatory system in the body. Ribosomes manufacture proteins and send them to parts of the cell where they are needed. They have similarities to the digestive system.

What organelles are in the circulatory system?

The organelles found in a animal cells are the cytoplasm,mitochondria,nucleus, cell membrane, ribosomes, Golgi body, and the ER. All these organs have a specific job that is used to help the cell function correctly. Most of your hearts is formed up by cardiac muscle tissues.

What makes up the ER of a cell?

The ER consists of the nuclear envelope and the peripheral ER, which includes smooth tubules and rough sheets. While the ER is defined as an interconnected network with a continuous membrane, the different structures that make up the ER perform very diverse and specialized functions within the cell.

What makes up the endoplasmic reticulum ( ER )?

Key Takeaways A cell’s endoplasmic reticulum (ER) contains a network of tubules and flattened sacs. Endoplasmic reticulum has two major regions: smooth endoplasmic reticulum and rough endoplasmic reticulum. Via the attached ribosomes, rough endoplasmic reticulum synthesizes proteins via the translation process.

How is the rough ER connected to the smooth ER?

Rough and smooth ER are typically connected to one another so that the proteins and membranes made by the rough ER can freely move into the smooth ER for transport to other parts of the cell. The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in plant and animal cells.

How is the ER connected to the nuclear envelope?

The ER is very extensive extending from the cell membrane through the cytoplasm and forming a continuous connection with the nuclear envelope. Since the ER is connected with the nuclear envelope, the lumen of the ER and the space inside the nuclear envelope are part of the same compartment.
