Question

drag a label into each box to best complete the model of plant structure complexity. cells organs tissues organ system increasing complexity plant structure complexity structures of a plant stem leaf (organ) plant tissue epidermal cells palisade cells spongy cells guard cells

Explanation:

In a plant, cells are the basic unit. Tissues are groups of similar cells working together. Organs are made up of different tissues, and organ - systems are composed of multiple organs. For example, guard cells are part of plant tissues, leaves are organs, and the root - shoot system is an organ - system. We arrange them according to the biological hierarchy of increasing complexity.

Answer:

From top to bottom (increasing complexity): cells, tissues, organs, organ system
