Plant Transport and Tissue Functions

The video tutorial from GYA Academy covers plant growth, focusing on cell division and tissue types. It explains meristematic and mature tissues, their functions, and how they contribute to plant growth. The video also discusses support and transport tissues, such as xylem and phloem, and their roles in water and mineral transport. Practice questions are provided to reinforce learning, and the video concludes with a summary of key points.
