CBSE Class 10 - Biology - Study Notes about Plant Growth Hormones (Phytohormones) (#cbseNotes)


Plant hormones or phytohormones are small, simple chemical molecules, which are present in low concentration in plants and regulate growth, differentiation and development.


Two Categories of Phytohormones:

Plant growth promoters: Examples are auxins, gibberellins and cytokinins.
Plant growth inhibitors: Examples are abscisic acid, ethylene.


All about Auxins
Auxins are weakly acidic growth hormones.

CBSE Class 12 - Informatics Practices - Java Object Oriented Programming-2 - Inheritance (#cbseNotes)


Q1: What do you mean by the term 'inheritance'?

Answer: In OOPs, Inheritance is the process of creating new class (Derived Class or sub-classes) from an existing class (Base Class or Super class). A Sub-class inherits all the properties (data members) and behaviour (method members) of the parent class (Super-class).

The level of Inheritance may be extended i.e. A Sub-class may have their own sub-classes.

In Real-life most of the things exhibit Inheritance relationship.


Q2: What is the importance of 'inheriatnce'?

Answer: Inheritance is important for the following reasons:
Modelling of Real-world
Reusability of codes
Transitive nature of Inheritance
