Chapter 30, Problem 3TYKT
Summary Introduction
To examine: Whether the statement “Gametophyte generation is most reduced in the gymnosperms” is true or false
Concept introduction: The word gymnosperm is derived from the Greek word gymnospermous, which means naked seeds. This plant is characterized by the absence of flowers. It consists of needle-shaped leaves and sunken stomata that involve the reduction of water loss during transpiration. Wind pollination is usually seen in this type of plants.
