Study questions1.The plant body is formed by the shoot and root systems. Explain how stem cells form the whole body of the plant. Discuss how an over proliferation of stem cells in the shoot apical meristem may increase productivity of the plant, expressed as number of fruits and seeds.2.Mention the characteristics of three plant tissue systems. Explain in a mechanistic manner how a mutation in a critical gene is responsible for the formation of epidermis affect the whole functioning of the plant. Give this explanation based on the effects of the epidermis in the function of the other plant tissue systems.3.Mention the characteristics of the cells that form the ground tissue. What cells would be affected by a deficiency of lignin biosynthesis and how this deficiency would affect the functions of the ground tissue
