Topic 2: Organisation of the Organism

Cells: Basic units of life, specialized for specific functions
Ciliated Cells: Move mucus in the trachea using tiny hairs (cilia)
Root Hair Cells: Absorb water and ions from the soil, increased surface area for absorption
Xylem Vessels: Transport water and support plants, no cytoplasm or end walls for efficient water flow
Palisade Mesophyll: Photosynthesis, tightly packed cells with numerous chloroplasts
Nerve Cells: Conduct nerve impulses, long axons with branches for rapid signal transmission
Red Blood Cells: Transport oxygen, no nucleus for more space for oxygen-carrying hemoglobin, biconcave shape
Sperm Cells: Reproduction, tail for movement, mitochondria for energy, multiple sperm prevention
Egg Cells: Reproduction, large size, energy stores for development, multiple sperm prevention

Tissues

Tissues: Groups of similar cells working together, performing a shared function (e.g., muscle tissue, palisade mesophyll)

Organs

Organs: Structures made of multiple tissues working together to perform specific tasks (e.g., heart, kidney, leaves)

Organ Systems

Organ Systems: Groups of organs working together for related functions (e.g., digestive system, circulatory system)

Cell Specialization

Specialized cells exhibit specific adaptations for optimal function in their roles. (e.g., shape, size, and internal structure)

Explore the diverse structures and functions of various cells and tissues in living organisms. This quiz covers specialized cells like nerve, red blood, and plant tissues, detailing their unique roles and characteristics. Test your knowledge on how these components work together to support life.
