From simplest to most complex, which list correctly orders levels of cell organization?

Specialised cells are adapted to perform specific functions within an organism, differing from general cells.
Examples include red blood cells, neurones, ciliated cells, root hair cells, and palisade cells.

Red Blood Cells (RBCs)
- Function: Transport oxygen in the bloodstream.
- Structure: Biconcave disc shape enhances surface area for oxygen absorption; lacks a nucleus increasing haemoglobin volume.
Neurones
- Function: Transmit nerve impulses throughout the body.
- Structure: Long extensions to quickly carry electrical signals; connected at each end for efficient communication.
Ciliated Epithelial Cells
- Function: Move mucus and trap dust in the respiratory tract.
- Structure: Cilia (hair-like structures) on the surface sweep away mucus; high mitochondria content provides energy for ciliary movement.
White Blood Cells (WBCs)
- Function: Protect the body against diseases.
- Structure: Flexible shape allows movement through tissues; can produce antibodies or engulf pathogens.
Smooth Muscle Cells
- Function: Move food through the digestive tract.
- Structure: Spindle shape allows contraction and relaxation, forming muscular tissues around organs like the stomach and intestines.

Root Hair Cells
- Function: Absorb water and minerals from the soil.
- Structure: Large surface area enhances water uptake efficiency.
Palisade Cells
- Function: Conduct photosynthesis by absorbing sunlight.
- Structure: High density of chloroplasts arranged closely to maximize light absorption.
Pollen Grains
- Function: Facilitate fertilization of egg cells.
- Structure: Tiny and lightweight for easy dispersal; thick walls protect genetic material.

Cells conduct specific operations, then group into tissues.
Tissues combine to form organs.
Organs work together in organ systems, ultimately forming an organism.
Hierarchical organization progresses from cells to organisms, with each level depending on the previous one for function and survival.
