Tissues are formed from the assemblage of cells and intercellular materials in various proportions in which one component predominates. In nervous tissue as an example, nerve cells predominate while in connective tissues such as Ligaments and Tendons, intercellular fibrous materials predominate.

Certain plants, like gymnosperms, produce seeds but lack fruits. Gymnosperms, including pine trees and cycads, have exposed seeds on cone scales, distinguishing them from angiosperms, which produce seeds enclosed within fruits. The absence of a fruit covering the seed is a characteristic feature of gymnosperms, a group of seed-producing plants.
