 What is Living? NCERT Biology Short Notes with Examples What is Living? Easy NEET Biology notes explaining the five defining characteristics of living organisms. What is Living? – Short Notes for NEET   - Dr.Sanjaykumar Pawar  Living Organisms Living organisms are those that grow, reproduce, perform metabolism, have cellular organisation, and respond to their surroundings (consciousness).

In non-living things , growth is external (by accumulation of material). Example: Mountains and sand dunes grow by deposition. NEET Point: ➡️ Growth alone is NOT a defining feature of living organisms because non-living things also show growth. 2. Reproduction Reproduction means producing new individuals of the same species . It occurs by: Sexual reproduction Asexual reproduction Asexu...

  Forebrain, Midbrain and Hindbrain – Easy NEET Notes 18.4.1 Forebrain Forebrain consists of: Cerebrum Thalamus Hypothalamus These are the major parts of the forebrain. Cerebrum Cerebrum is the largest part of the human brain . It controls: Thinking Intelligence Memory Learning Speech Voluntary actions Cerebral Hemispheres A deep groove divides the cerebrum into: Left cerebral hemisphere Right cerebral hemisphere Corpus Callosum Both hemispheres are connected by nerve fibres called: Corpus callosum It allows communication between the two hemispheres. Cerebral Cortex Outer layer of cerebrum is called the cerebral cortex . It is highly folded to increase surface area. It appears grey due to presence of neuron cell bodies. Therefore, it is called Grey Matter . Functions of Cerebral Cortex It contains: Motor areas → control voluntary movements. Sensory areas → receive sensory impulses. Association areas → involved in: Memory Inte...
