Water behaves as an amphoteric substance because it has the ability to act as both an acid and a base. This means that it can donate a proton (H+) to another substance, acting as an acid, or accept a proton, acting as a base.

Explanation:

1. Definition of an amphoteric substance:
- An amphoteric substance is one that can act as both an acid and a base, depending on the reaction conditions.
- It can donate a proton (H+) to another substance, acting as an acid, or accept a proton, acting as a base.

2. Water as an amphoteric substance:
- Water (H2O) is a prime example of an amphoteric substance.
- It can act as an acid by donating a proton (H+). In this case, water can ionize to form hydronium ions (H3O+) and hydroxide ions (OH-): H2O + H2O ⇌ H3O+ + OH-
- It can also act as a base by accepting a proton (H+). In this case, water can react with an acid to form hydronium ions (H3O+): HCl + H2O → H3O+ + Cl-

3. Acidic and basic properties of water:
- In pure water, a small proportion of water molecules will undergo self-ionization to form hydronium and hydroxide ions.
- The concentration of hydronium ions (H3O+) and hydroxide ions (OH-) in pure water is equal, leading to a neutral pH of 7.
- When an acid is added to water, the concentration of hydronium ions increases, making the solution acidic (pH less than 7).
- When a base is added to water, the concentration of hydroxide ions increases, making the solution basic or alkaline (pH greater than 7).

Conclusion:
Water behaves as an amphoteric substance because it has the ability to act as both an acid and a base. This unique property allows water to participate in a wide range of chemical reactions and makes it essential for various biological and chemical processes.

Root and StemDefinition of RootA root is an underground part of a plant that typically lacks nodes, leaves, and buds. It is responsible for anchoring the plant in the soil, absorbing water and minerals, and storing nutrients. Roots can be classified into two types: taproots and fibrous roots.Definition of StemA stem is the aboveground part of a plant that supports leaves, flowers, and fruits. It contains nodes, internodes, and buds. The primary functions of a stem are to transport water, nutrients, and sugars between the roots and the leaves, provide structural support, and facilitate the growth of the plant.Differences between Root and Stem1. Structure- Root: Roots are typically found underground and have no nodes or leaves. They have a central primary root, known as the taproot, from which smaller lateral roots branch out.- Stem: Stems are found aboveground and have nodes, internodes, leaves, and buds. They have a central main stem, known as the shoot, from which lateral branches and leaves arise.2. Function- Root: The main functions of roots are anchoring the plant in the soil, absorbing water and minerals, storing nutrients, and providing support.- Stem: Stems have several functions, including transporting water, minerals, and sugars between the roots and leaves, providing structural support, and facilitating growth and reproduction.3. Location- Root: Roots are typically found below the soil surface, although some plants have aboveground roots called aerial roots.- Stem: Stems are generally located above the ground, but they can also be partially or entirely underground.4. Growth- Root: Roots grow in length from the root tip and branches develop from the primary root.- Stem: Stems grow in height from the apical meristem located at the tip of the stem. This growth allows the plant to reach sunlight and maximize photosynthesis.5. Types- Root: Roots can be classified as taproots or fibrous roots based on their structure and branching pattern.- Stem: Stems can be classified as herbaceous or woody based on their texture and ability to undergo secondary growth.ConclusionIn summary, roots and stems are essential parts of a plant with distinct structures and functions. Roots are primarily responsible for anchoring the plant, absorbing water and minerals, and storing nutrients. Stems, on the other hand, support leaves, flowers, and fruits, transport substances throughout the plant, and provide structural support. Understanding the differences between roots and stems helps us appreciate the complexity and diversity of plant anatomy and physiology.
