Write the functions of following cell organelles.
a) Ribosomes
b) Vacuole
c) Golgi complex
d) Nucleus
e) Smooth endoplasmic reticulum (SER)
Answers
Answer:
A
Explanation:
the ER Play a number of role with in a cell for protein synthesis
a)Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).
b)Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa, vacuoles are cytoplasmic organs (organelles), performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.
c)The golgi apparatus modifies proteins and lipids that is receives from the endoplasmic reticulum. These biochemicals leave the golgi by exocytosis before being delivered to different intracellular or extracellular targets.
d)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. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.
e)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.
