Function: Rough endoplasmic reticula are involved in the synthesis of proteins.
What is a cell organelle?
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.
What is the function of the smooth ER?
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.

MICROVILLI = extensions of the plasma membrane that serve primarily to increase the cells surface area.
What is the function of smooth ER?
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.
What is the function of rough and smooth endoplasmic reticulum in a plant cell?
The main function of the rough ER is to make protein, which is in contrast to the smooth endoplasmic reticulum. The function of the smooth ER is to synthesize lipids and help detoxify the cell.
What is the function of cell?
They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves.
What are all the organelles?
6 Cell Organelles
- Nucleus. Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid). …
- Ribosomes. Ribosomes are the protein factories of the cell. …
- Endoplasmic reticulum. …
- Golgi apparatus. …
- Chloroplasts. …
- Mitochondria.
What is the function of lysosomes?
Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.
What is the function of the ribosomes?
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.
What are the structure and functions of organelles?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
What are the types of organelles?
Major eukaryotic organelles
| Organelle | Main function |
|---|---|
| mitochondrion | energy production from the oxidation of glucose substances and the release of adenosine triphosphate |
| nucleus | DNA maintenance, controls all activities of the cell, RNA transcription |
| vacuole | storage, transportation, helps maintain homeostasis |
What are the extensions of the plasma membrane that serve primarily to increase?
Terms in this set (82)
- Extensions of the plasma membrane that serve primarily to increase the cell's surface area are known as: …
- Brush border, role with absorption. …
- Propulsion of cell. …
- Some are motile, with power and recovery strokes.
What are extensions of the plasma membrane that serve primarily to increase a cell’s surface area called?
The plasma membranes of cells that specialize in absorption are folded into fingerlike projections called microvilli (singular = microvillus). This folding increases the surface area of the plasma membrane.
What is the function of SER and RER?
Difference between Smooth and Rough Endoplasmic Reticulum
| Rough Endoplasmic Reticulum (RER) | Smooth Endoplasmic Reticulum (SER) |
|---|---|
| It participates in the synthesis of enzymes and proteins. | Synthesises glycogen, lipids and steroids. |
| It helps in the formation of lysosomes. | Gives rise to Spherosomes/ Oleosomes |
What is cytoplasm function?
Cytoplasm. The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
How many organelles are in a cell?
What Are The 12 Organelles In A Cell?
- Nucleus.
- Ribosomes.
- Endoplasmic reticulum.
- Golgi Apparatus.
- Mitochondria.
- Chloroplast.
- Vacuole.
- Centriole.
What is the function of nucleus?
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.
What is cell function?
They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
What are the functions of the organelles in plant and animal cells?
Cells are made up of small organ-like structures called organelles. Each organelle has a specific function that helps the cell function as a whole….
| Name of organelle | Function | Where found |
|---|---|---|
| cell wall | -rigid, outermost layer of the plant cell -shapes, protects & supports the cell | *plant cells only |
What is the function of chloroplast?
