location and function of the following :-
a)Endoplasmic reticulum
b) Ribosomes
c) Golgi apparatus
d) lysosomes
e) centrosomes
Answers
Endoplasmic reticulum
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 protein
Golgi apparatus
It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus. While many types of cells contain only one or several Golgi apparatus, plant cells can contain hundreds.
Ribosome
Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum
.
Lysosomes
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
Centrosome
In cell biology, the centrosome (Latin centrum 'center' + Greek sōma 'body') (also called cytocenter[1]) is an organelle that serves as the main microtubule organizing center (MTOC) of the animal cell, as well as a regulator of cell-cycle progression. The centrosome provides structure for the cell. The centrosome is thought to have evolved only in the metazoan lineage of eukaryotic cells.[2] Fungi and plants lack centrosomes and therefore use other structures to organize their microtubules.[3][4] Although the centrosome has a key role in efficient mitosis in animal cells, it is not essential in certain fly and flatworm species.[5][6][7]
