Where is the smooth endoplasmic reticulum found plant or animal?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
What is the smooth endoplasmic reticulum responsible for?
smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular …
What is the function and location of the rough endoplasmic 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.
Do plants have smooth ER?
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 does Golgi apparatus do?
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
What is the difference between rough ER and smooth ER?
The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.
What would happen without the smooth ER?
The smooth ER has an important role in lipid and organic compound synthesis, it is a storage for intracellular calcium as well. Without ER in the skeletal muscle fibers couldn’t happen muscle contraction. In the absence of these cellular mechanisms the cell would probably die.
How does the smooth ER make lipids?
The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes. … In the reproductive organs, smooth ER in the cells produces the organic compound hormones testosterone and estrogen.
What do smooth endoplasmic reticulum ER and rough ER have in common?
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. … Smooth ER (SER) acts as a storage organelle.
Where is nucleolus found?
The nucleolus is a region found within the cell nucleus that is concerned with producing and assembling the cell’s ribosomes.
What is the difference between a rough endoplasmic reticulum and a smooth endoplasmic reticulum How does endoplasmic reticulum help in membrane biogenesis?
How is endoplasmic reticulum important for membrane biogenesis? – Biology Q&A.
Differentiate between rough and smooth endoplasmic reticulum.
Differentiate between rough and smooth endoplasmic reticulum.
|Rough Endoplasmic Reticulum (RER)||Smooth Endoplasmic Reticulum (SER)|
|It possesses ribosomes attached to its membrane.||It does not have ribosomes on its membrane.|
|Formed of cisternae and a few tubules.||Formed of vesicles and tubules.|
What do the nucleus and the smooth endoplasmic reticulum have in common?
The nucleus and the smooth endoplasmic reticulum both are membrane bound organelles and are connected into one continuous membrane.
Where is the cytoplasm located?
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.
Where is the location of ribosomes?
Ribosomes are mainly found bound to the endoplasmic reticulum and the nuclear envelope, as well as freely scattered throughout the cytoplasm, depending upon whether the cell is plant, animal, or bacteria.
Where is the nucleus location?
The nucleus is found in the middle of the cells, and it contains DNA arranged in chromosomes. It is surrounded by the nuclear envelope, a double nuclear membrane (outer and inner), which separates the nucleus from the cytoplasm. The outer membrane is continuous with the rough endoplasmic reticulum.
Where is the lysosome located?
Lysosomes are a membrane enclosed sac of enzymes that are found in the cytosol of the cytoplasm of an eukaryotic cell. The lysosomes are located in the cytosol of the cytoplasm in a eukaryotic cell.
Where is cytoskeleton located?
cytoskeleton, a system of filaments or fibres that is present in the cytoplasm of eukaryotic cells (cells containing a nucleus).
Where is the cell membrane located?
The cell membrane is located on the outside of a cell. It acts as a border that separates the cell from other cells or substances in the environment.
Where are lysosomes most abundant?
Lysosomes are particularly abundant in secretory cells e.g. epithelial cells, and in phagocytic cells. For example, there are many lysosomes in liver cells – two of the main functions of the liver being (1.)
Where are vacuoles located?
vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid.
Where is the cell membrane located in a prokaryotic cell?
Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.
Which cell would you find the most smooth ER?
Large amounts of smooth endoplasmic reticulum are found in cells that specialize in lipid metabolism. For instance, liver cells remove alcohol and drugs from the bloodstream. Liver cells have an impressive network of smooth endoplasmic reticulum.
