Tissues: groups of similar cells

Organisation • Principles of organisation

Key concepts

What you'll likely be quizzed about

  • A tissue is a collection of cells with comparable structures and a unified primary function.
  • These similar cells produce collective effects: structural specialization enhances the efficiency of shared functions.
  • Tissues serve as the intermediate organizational level between individual cells and entire organs, demonstrating how cell specialization confers distinct properties to tissues.

Why does muscle tissue contract effectively?

Click to reveal answer

Muscle cells contain contractile proteins arranged to enable coordinated contractions that produce force and movement.

Key notes

Important points to keep in mind

Tissue = similar cells + shared function; connects cells to organs.

Cell structure specialization leads to specialized tissue function.

Tissues combine to form organs; organ function depends on all tissues.

Diffusion limits necessitate transport systems or increased surface area.

Plant vascular tissues (xylem, phloem) enable transport and support; structural changes impact efficiency.

Damage to one tissue type reduces the overall performance of the organ.
