Final answer:
Plant tissues are classified as simple or complex based on cell similarity. Simple tissues have similar cell types, while complex tissues have different cell types combined for specific functions like transportation in vascular tissues.
Step-by-step explanation:
Plant tissues are classified as either simple or complex tissues. Simple tissues consist of similar cell types performing similar functions, such as dermal tissue and ground tissue. The dermal tissue is the plant's outer layer that performs protective functions, while the ground tissue is involved in photosynthesis and provides support to the plant.
On the other hand, complex tissues like vascular tissue consist of different cell types working together to conduct water, minerals, and photosynthetic products throughout the plant. This vascular tissue includes the xylem, which transports water and nutrients, and the phloem, which distributes photosynthetic products.
Therefore, the basis for classifying plant tissues into simple and complex is based on whether they are composed of similar or different types of cells. Examples of these tissues include dermal tissue as a simple tissue and vascular tissue as a complex tissue, each performing essential functions for the plant's survival and growth.
