Describe or draw a labelled diagram of the external structure of an Agama lizard. How are birds adapted to their mode of feeding? How is water important to plants?

Water is essential for plants as it is a key reactant in photosynthesis, the process by which plants produce food. It also acts as a solvent, facilitating the transport of minerals from the soil to various parts of the plant and sugars from leaves to other tissues. Water maintains turgor pressure within plant cells, providing structural support and keeping the plant upright. Additionally, transpiration, the evaporation of water from leaves, helps regulate the plant's temperature.
