Question

Define :-
(i) a peptide bond

(ii) pH
(iii)polyribosomes

(iv) Plasmodesmata​

Answer 1

$\huge\mathcal\underline{Peptide\: Bond:}$

In Proteins, the Amino Acids are joined together by a Peptide Bond. A peptide bond is formed between 2 molecules, one of Carboxylic group reacts with Amino group of other molecule & releasing a water molecule.

$\huge\mathcal\underline{pH:}$

It stands for Potenz "power" Hydrogen. It's value is from 1-14, where below 7 indicates Acidity & above 7 indicates Alkalinity.

$\huge\mathcal\underline{Polyribosomes:}$

As the name suggests, a Cluster of Ribosome together is known as Polyribosomes.

$\huge\mathcal\underline{Plasmodesmata:}$

When a narrow thread-like amount of Cytoplasm passes through the cell wall of adjacent plant cells & allows communication between them is referred as Plasmodesmata.

Hope it helps you :)
