What is Endoplasm in biology?
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.
What are the two types of Endoplasm?
The ER can be classified in two functionally distinct forms: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER).
What is the function of Endoplasm 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. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Are Endoplasm and cytoplasm the same?
Endoplasm is the inner granulated, dense part of a cell’s cytoplasm and ectoplasm is the outer non-granulated layer of the cytoplasm. Cytoplasm-It is a jelly like semi fluid general mass of protoplasm excluding the nucleus but including all other components-cytoplasmic matrix,cell organelles,and cell inclusions.
How many types of Endoplasm are there?
The endoplasmic reticulum is classified into two types: Smooth endoplasmic reticulum. Rough endoplasmic reticulum.
What is the function of endoplasm and ectoplasm?
Ectoplasm, which is the outer layer of the cytoplasm, is responsible for the direction of the movement of the cell. However, endoplasm is responsible for regulating the concentration of water inside the cell. It can easily absorb and release water due to the presence of a partial membrane in amoeba.
Why is rough ER bumpy?
Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface.
What is endoplasm in protozoa?
In most protozoa the cytoplasm is differentiated into ectoplasm (the outer, transparent layer) and endoplasm (the inner layer containing organelles); the structure of the cytoplasm is most easily seen in species with projecting pseudopodia, such as the amebas.
What is the function of ectoplasm?
Ectoplasm is the outer part of the cytoplasm. It is located adjacent to the cell membrane and helps the membrane to maintain elasticity. It is less dense and not granulated. However, ectoplasm is responsible for locomotion of amoeba cell.
What are two types of ER and what do they do?
The two types of endoplasmic reticulum are : Rough Endoplasmic Reticulum: Their main function is produce proteins in the cells and ribosomes are attached to their surface. Smooth Endoplasmic Reticulum: Their main function is to produce lipids and also detoxify toxins in the body in the liver and kidney cells.
What is endoplasm or Exoplasm?
Complete answer: The endoplasm generally refers to the inner and dense part of the cytoplasm of the cell, whereas the ectoplasm is the outer layer of the cytoplasm and is typically watery and immediately adjacent to the plasma membrane.
What are rough ER jobs?
Smooth ER Function
|Endoplasmic Reticulum Type||Structure||Function|
|Rough||Membraneous organelle covered in ribosomes||Makes proteins destined for secretion, the plasma membrane or the endomembrane system|
|Smooth||Membraneous organelle without ribosomes||Makes lipids and detoxifies the cell|
What is RER and SER in biology?
Rough Endoplasmic Reticulum (RER) Smooth Endoplasmic Reticulum (SER) It possesses ribosomes attached to its membrane. It does not have ribosomes on its membrane. It is formed of cisternae and a few tubules. It is formed of vesicles and tubules.
What do smooth and rough ER do?
The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.
What is the function of the endoplasm in a cell?
The endoplasm is necessary for most metabolic activities, including cell division. The endoplasm, like the cytoplasm, is far from static. It is in a constant state of flux through intracellular transport, as vesicles are shuttled between organelles and to/from the plasma membrane.
What is endoplasmic reticulum?
Endoplasmic Reticulum Definition “Endoplasmic Reticulum is a complex network of tubular membranes exclusively present in the cytoplasm of the eukaryotic cell.” What is Endoplasmic Reticulum? Endoplasmic reticulum transpires in two forms: a type with ribosome-studded surface and another with a smooth surface.
What is the difference between ectoplasm and endoplasm?
Endoplasm. 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. These two terms are mainly used to describe the cytoplasm of the amoeba,…
What is ectoplasm and endoplasm in amoeba?
Endoplasm. These two terms are mainly used to describe the cytoplasm of the amoeba, a protozoan, eukaryotic cell. The nucleus is separated from the endoplasm by the nuclear envelope. The different makeups/viscosities of the endoplasm and ectoplasm contribute to the amoeba’s locomotion through the formation of a pseudopod.
