FAQs on Adaptations in Plants: Solved Practice Questions - 2
| 1. What are the main types of adaptations in plants? |  |
Ans. The main types of adaptations in plants include structural adaptations, which are physical features that help plants survive in their environment, such as thick leaves in cacti to reduce water loss; behavioural adaptations, which are actions that help plants respond to their environment, like closing leaves at night; and physiological adaptations, which involve internal processes, such as the ability of some plants to store water in their tissues.
| 2. How do desert plants adapt to their environment? | |
Ans. Desert plants adapt to their environment through various mechanisms. They often have thick, waxy skins to reduce water loss, deep root systems to access underground water, and special leaves that may be modified into spines to minimise surface area. Some desert plants also have the ability to store water in their tissues to survive long periods of drought.
| 3. Why do some plants have broad leaves while others have needle-like leaves? | |
Ans. Plants with broad leaves generally grow in areas with abundant sunlight and rainfall, as their larger surface area allows for more efficient photosynthesis. In contrast, plants with needle-like leaves, such as evergreens, are often found in colder or dryer climates. These needle-like leaves reduce water loss and can withstand harsh weather conditions, making them well-suited for their environment.
| 4. What role do root adaptations play in plant survival? | |
Ans. Root adaptations are crucial for plant survival as they enable plants to access water and nutrients from the soil. For example, some plants have deep taproots that reach water far below the surface, while others have widespread fibrous root systems that can quickly absorb moisture from light rains. These adaptations help plants thrive in varying environmental conditions.
| 5. How do aquatic plants differ from terrestrial plants in their adaptations? | |
Ans. Aquatic plants differ from terrestrial plants in several adaptations. Aquatic plants often have flexible stems to withstand water currents, air-filled spaces to help them float, and thin leaves to facilitate gas exchange. Terrestrial plants, on the other hand, have thicker stems and leaves to support their structure and reduce water loss, reflecting their need to survive in land-based environments.
