What is the endoplasmic reticulum compared to?

Endoplasmic Reticulum – Wrapping it Up

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 .

Also Know, what are the 3 main functions of the endoplasmic reticulum? It plays a major role in the production, processing, and transport of proteins and lipids. The ER produces transmembrane proteins and lipids for its membrane and many other cell components including lysosomes, secretory vesicles, the Golgi appatatus, the cell membrane, and plant cell vacuoles.

Accordingly, what would the endoplasmic reticulum be in a house?

The endoplasmic reticulum, or ER, transports things across the cell, and helps make proteins and lipids. The mitochondrion are like the electricity in a house. Electricity supplies a house with all its energy to perform its daily functions such as heating and air conditioning. Vacuoles store food and water for cells.

What would the endoplasmic reticulum be in a school?

The rough endoplasmic reticulum transports proteins, like how a school bus transports students. A cell wall provides structure and shape to the cell, and the walls do the same for a school.

What color is the endoplasmic reticulum?

Color Suggestions: o Cell Membrane – Pink o Cytoplasm – Yellow o Vacuole – Light Black o Nucleus – Blue o Mitochondria – Red o Ribosomes – Brown o Endoplasmic Reticulum – Purple o Lisosome – Light Green o Golgi Body – Orange 2.

Where is the endoplasmic reticulum found?

ROUGH ENDOPLASMIC RETICULUM Rough ER is found throughout the cell but the density is higher near the nucleus and the Golgi apparatus. Ribosomes on the rough endoplasmic reticulum are called ‘membrane bound’ and are responsible for the assembly of many proteins. This process is called translation.

How can you remember the endoplasmic reticulum?

Terms in this set (11) nucleus. the brain of the cell. mitochondria. the powerhouse of the cell. golgi apparatus/body. the “mailroom” to the E.R. endoplasmic reticulum (E.R.) the “highway” of the cell. vacuole. stores food, water, and other waste. cell membrane. controls what goes in and out of the cell. cytoplasm. ribosome.

What is the endoplasmic reticulum made of?

Endoplasmic reticulum is made up of a network of folded membranes much like the plasma membrane and is generally contiguous with the nuclear and plasma membrane. Membranes are composed of a phospholipid bilayer with proteins embedded and are selectively permeable.

What is a rough endoplasmic reticulum?

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.

How does the endoplasmic reticulum work?

Endoplasmic Reticulum – Wrapping it Up Another organelle in the cell is the endoplasmic reticulum (ER). While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and packaging system. It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA.

How big is the endoplasmic reticulum?

a ER sheets and tubules have a diameter of 30–50 nm in eukaryotes.

Who discovered the endoplasmic reticulum?

Discovery of Endoplasmic Reticulum (ER): It was discovered independently by Porter (1945) and Thompson (1945). The name was given by Porter in 1953. Endoplasmic reticulum is a 3-dimensional, complicated and interconnected syncrri of membrane-lined channels that run through the cytoplasm.

What is the cytoplasm in a house?

The cytoplasm is like the floor in a house because the floor contains all the parts of the house and holds them together, like the cytoplasm does for the cell. The large vacuole is like the closet in a house because the closet is the main storage area in a house, like the vacuole is in a cell.

What is a lysosome like?

Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. Lysosomes are like the stomach of the cell.

What is an analogy for endoplasmic reticulum?

The endoplasmic reticulum creates a network of membranes found throughout the whole cell. These would be analogous to the stairs and hallways. They help us get from place to place.

What is a Golgi apparatus in a house?

The Golgi Apparatus sorts and packages proteins for distribution around the cell. Ribosomes make proteins according to instructions given out by the DNA. It is like the door of the house which controls what goes in and out of the house. The Cell Membrane controls what goes in and out of the cell.

What is a endoplasmic reticulum like in real life?

Rough Endoplasmic Reticulum It is more like a thick gel than a watery substance, but it liquefies when shaken or stirred. The cytoplasm provides support for the internal structure of the cell. A real life example of this organelle would be lawns and parks.

What is a nucleus like in a house?

The nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes. Mitochondria are responsible for ATP production; the endoplasmic reticulum modifies proteins and synthesizes lipids; and the golgi apparatus is where the sorting of lipids and proteins takes place.
