FAQs on Infographics -2: Transportation in Animals and Plants - Science Class 7 (Old NCERT)

1. What are the main modes of transportation in animals?
Ans. Animals have various modes of transportation, including walking, flying, swimming, and crawling. These movements are adapted to their environments and needs. For instance, birds use wings to fly, while fish have fins for swimming. Land animals like elephants and horses walk or run, utilizing their legs for mobility.
2. How do plants transport nutrients and water?
Ans. Plants transport nutrients and water through specialized tissues known as xylem and phloem. The xylem carries water and dissolved minerals from the roots to the leaves, while the phloem distributes sugars produced during photosynthesis from the leaves to other parts of the plant.
3. What role does transpiration play in plant transportation?
Ans. Transpiration is the process where water evaporates from the leaves of plants. This loss of water creates a negative pressure that helps pull more water and nutrients up from the roots through the xylem. It is essential for maintaining hydration and facilitating nutrient transportation within the plant.
4. How do animals adapt their transportation methods in different environments?
Ans. Animals adapt their transportation methods based on their habitats. For example, desert animals may have evolved to travel long distances without water, using efficient locomotion to conserve energy. Aquatic animals have streamlined bodies for swimming, while flying animals have developed lightweight structures for flight, showcasing the diversity of adaptations.
5. What is the significance of transportation systems in ecosystems?
Ans. Transportation systems in ecosystems are crucial because they ensure that nutrients, water, and energy are distributed efficiently among organisms. This connectivity supports food webs, maintains biodiversity, and helps in nutrient cycling, which are essential for ecosystem health and sustainability.
