Chapter 32, Problem 3TY
Summary Introduction
Introduction: The gymnosperms are one of the important members of the plant community. They were the first plants to have seed and dominant sporophytic stage in their life cycle. They also form wood by secondary growth, have eustele and consist of one of the largest growing plants in the world. They are mostly present in the temperate region of the northern hemisphere where they are more dominant than
