Living Organisms Classification

Five kingdoms: Animals, Plants, Fungi, Protists, and Prokaryotes.
The first four kingdoms are eukaryotic organisms, containing a nucleus.
Prokaryotes are single-celled organisms lacking a nucleus.
Examples of prokaryotes include bacteria.

Eukaryotic Cell Structure

Both plants and animals are eukaryotic cells.
They contain a nucleus, cell membrane, mitochondria, ribosomes, and cytoplasm.

Animal Cell Structure

Nucleus: Contains DNA controlling cellular activity.
Cell Membrane: Encloses the cell, regulating substance entry and exit.
Mitochondria: Site of aerobic respiration for energy production.
Ribosomes: Found on the rough endoplasmic reticulum and responsible for protein synthesis.
Cytoplasm: Gel-like substance filled with dissolved solutes, hosting numerous chemical reactions.

Plant Cell Structure

Possess all the components of animal cells.
Unique structures include:
- Cell wall: Made of cellulose, providing support and defining shape.
- Chloroplast: Contain chlorophyll for photosynthesis, absorbing light energy.
- Permanent vacuole: Filled with cell sap, used for storage and cell shape maintenance.

Fungi Characteristics

Mostly multicellular, except for single-celled yeasts.
Multicellular fungi consist of thread-like hyphae, forming a network called mycelium.
Contain a nucleus and cell walls made of chitin.
Lack chloroplasts and cannot photosynthesize.
Feed saprotrophically, secreting enzymes to digest food before absorbing nutrients.
Some fungi are parasitic, consuming living material.
Store carbohydrates as glycogen.
Examples include moulds, mushrooms, yeasts.

Fungal Cell Structure

Contains nucleus, cell membrane, ribosomes, mitochondria, cytoplasm, and a cell wall made of chitin.
