Plant Structure and Function Concepts

The video provides an overview of plant organs and tissues, focusing on roots, stems, leaves, and flowers. It explains the functions of these organs, such as water and mineral absorption by roots, transport by stems, photosynthesis by leaves, and reproduction by flowers. The video also covers the structure and roles of different tissues, including epidermal, xylem, phloem, and mesophyll tissues, highlighting their importance in plant biology.

What is the primary difference between an organ and a tissue in plants?

• An organ is a group of similar cells, while a tissue is a group of different tissues.

• An organ is a group of different tissues, while a tissue is a group of similar cells.

• An organ is a single cell, while a tissue is a group of organs.
