What does endoplasmic mean? (EN-doh-PLAZ-mik reh-TIH-kyoo-lum)
A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell
.
What does endoplasmic reticulum literally mean?
Why is it called endoplasmic?
What is an example of endoplasmic?
How do you say endoplasmic?
Where is the endoplasmic reticulum?
The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs (cisternae) that
extends from the nuclear membrane throughout the cytoplasm
(Figure 9.1). The entire endoplasmic reticulum is enclosed by a continuous membrane and is the largest organelle of most eukaryotic cells.
What does reticulum mean in biology?
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 is another word for the endoplasmic reticulum?
| endoplasmatic reticulum ergastoplasm | rough ER sarcoplasmic reticulum | smooth ER |
|---|
What does ER RER and SER stand for?
ER stands for
endoplasmic reticulum
. RER stands for rough endoplasmic reticulum. SER stands for smooth endoplasmic reticulum.
Who named endoplasmic reticulum?
How did the endoplasmic reticulum ER get its name?
Porter distinguished the exoplasm, a peripheral region devoid of organelles, from the adjacent endoplasm.
In the endoplasm he detected a fine network of interconnected tubules, a reticulum
; hence, the name “endoplasmic reticulum” (ER).
What is an endoplasmic reticulum for kids?
The endoplasmic reticulum is a type of organelle. It’s
a collection of tubes that make, package, and transport proteins and fats
. The endoplasmic reticulum is a team player. It works with other organelles, including ribosomes, the Golgi apparatus and the nucleus.
How many ER are in a cell?
There are
two types of endoplasmic reticulum
: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells.
What are the 3 main functions of the endoplasmic reticulum?
The 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 the function of endoplasmic?
Why is endoplasmic reticulum important?
The endoplasmic reticulum (ER) is an important organelle in eukaryotic cells.
It plays a major role in the production, processing, and transport of proteins and lipids
.
What is endoplasmic reticulum made of?
What are ribosomes do?
A ribosome is an intercellular structure made of both RNA and protein, and it is
the site of protein synthesis in the cell
. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.
How do you use endoplasmic reticulum in a sentence?
Why are ribosomes attached to endoplasmic reticulum?
Proteins are assembled at organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum,
giving it a rough appearance
.
Why is the ER considered the circulatory system of the cell?
It’s analogous to the circulatory system in the body. 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.
What does SER stand for?
Ser is an abbreviation for
serial, series and sermon
. An example of ser is the unique string of numbers and letters used to identify a product, the seriel number. An example of ser is a pastor giving a speech about God in church, a sermon. abbreviation.
What carries ER products to Golgi?
What’s the difference between rough ER and smooth ER?
Smooth ER is derived from rough endoplasmic reticulum by sacrificing the ribosomes, whereas Rough ER originates from the nuclear membrane
. The main difference between the SER and RER is the presence of ribosomes, as SER does not consist of ribosomes but RER consists of ribosomes.
What does cytoplasm mean in science?
What does Endo mean in medical terminology?
What is endoplasm and ectoplasm?
Endoplasm generally refers to the inner (often granulated), dense part of a cell’s cytoplasm. This is opposed to the ectoplasm which is the outer (non-granulated) layer of the cytoplasm, which is typically watery and immediately adjacent to the plasma membrane.
