Overview of Class 9 Science – Diversity in Living Organisms

Introduction to Classification:

• Classification is the method of arranging living organisms into groups based on similarities and differences.
• It helps in understanding the relationship between different species and organisms.

Classification of Living Organisms:

• Five Kingdom Classification:
  • Monera: Unicellular, prokaryotic organisms (e.g., bacteria).
  • Protista: Unicellular, eukaryotic organisms (e.g., amoeba, paramecium).
  • Fungi: Multicellular, eukaryotic organisms that decompose organic matter (e.g., mushrooms).
  • Plantae: Multicellular, photosynthetic organisms (e.g., plants).
  • Animalia: Multicellular, heterotrophic organisms (e.g., animals).

Basis of Classification:

• Classification is based on characteristics like cell structure, body organization, mode of nutrition, and reproduction.

Plant and Animal Classification:

• Plant Kingdom:
  • Divided into various groups like algae, bryophytes, pteridophytes, gymnosperms, and angiosperms.
  • Based on the presence of vascular tissues, seeds, and flowers.
• Animal Kingdom:
  • Classified into various phyla such as Porifera, Cnidaria, Platyhelminthes, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata.
  • Based on body structure, symmetry, and other features.

Importance of Classification:

• Understanding classification helps in studying the evolution of organisms and their ecological roles.

Definition of Tissues:

• • A tissue is a group of similar cells that perform a specific function.
  • Tissues are important in multicellular organisms for performing coordinated functions.

Types of Plant Tissues:

• • Meristematic Tissue:
    • Found in growing regions of plants (tips of roots and shoots).
    • Responsible for plant growth.
  • Permanent Tissue:
    • Formed from meristematic tissue when it stops dividing.
    • Simple Tissues: Parenchyma, Collenchyma, and Sclerenchyma.
    • Complex Tissues: Xylem and Phloem (vascular tissues for transport).

Types of Animal Tissues:

• • Epithelial Tissue:
    • Covers body surfaces, lines organs and cavities.
    • Types: Squamous, Cuboidal, Columnar, and Ciliated.
  • Connective Tissue:
    • Supports and binds other tissues.
    • Types: Bone, Blood, Cartilage, Ligaments, Tendons.
  • Muscular Tissue:
    • Responsible for movement.
    • Types: Striated, Smooth, and Cardiac muscles.
  • Nervous Tissue:
    • Carries nerve impulses for coordination and response.
    • Composed of neurons.

Differences Between Plant and Animal Tissues:

• • Plant Tissues:
    • Help in growth (e.g., meristematic tissue) and transport of nutrients (e.g., xylem and phloem).
  • Animal Tissues:
    • Aid in movement (muscular tissue), protection (epithelial tissue), and response to stimuli (nervous tissue).

Functions of Tissues:

• • Tissues provide structural support, enable movement, transport materials, and allow communication within the body.

Tissue Repair and Regeneration:

• • The ability of tissues to heal and regenerate after injury.
  • Epithelial and connective tissues in animals have a high capacity for regeneration.

Special Features of Certain Tissues:

• • Sclerenchyma: Provides mechanical strength to plants.
  • Cardiac Muscle: Found in the heart; involuntary control.
  • Xylem and Phloem: Specialized for the transport of water and nutrients in plants.

Importance of Tissues in Organ Systems:

• • Tissues combine to form organs and organ systems in both plants and animals, playing a vital role in the functioning of living organisms.

Class 9 Science Chapter 7 – Diversity in Living Organisms FAQs

What is diversity in living organisms?

Diversity in living organisms refers to the variety of life forms, like plants, animals, and microorganisms, found on Earth.

What do you mean by diversity of organisms?

It means the different types of living beings in terms of species, habitat, and traits, creating a rich variety in nature.

What is the meaning of living diversity?

Living diversity is the wide range of living things that exist, from simple bacteria to complex animals and plants.

What is the reason for diversity in living organisms?

The diversity in living organisms comes from evolution, environmental factors, and genetic variation over time.

What are the important points in diversity in living organisms?

Key points include species variety, adaptations to different environments, and evolutionary processes.
