Important Questions & Answers: Transportation in Animals and Plants - NCERT Exemplar Class 7 Science
Are you looking for extra questions on transportation in animals and plants for grade 7 class? Animal transport, including circulation through arteries, veins and capillaries, is powered by a combination of heart contraction and muscle movement. In plants, sap with dissolved nutrients flows through tubes, known as xylem cells, from the roots to the leaves to nourish them. Extra questions may include topics such as how water is transported from one tissue to another in plants, or how different kinds of blood vessels help in the circulation of blood in mammals.
Transportation in plants and animals is a crucial concept in the study of biology, especially for class 7 students. Understanding how plants and animals move materials such as water, nutrients, gases, and wastes within their bodies is essential to comprehend their growth, development, and survival. One way to reinforce this knowledge is by using transportation in plants and animals class 7 worksheets with answers.
A transportation worksheet for class 7 can cover a range of topics, such as the transportation system in plants, the transport of food and minerals in plants, and the function of the heart in animals. It can also include questions about capillaries, blood vessels, the circulatory system, and excretion.
One important process in transportation in plants is transpiration. Transpiration is the loss of water vapor from plants' leaves through small openings called stomata. This process is important because it helps plants absorb water and minerals from the soil and transport them to other parts of the plant. A worksheet on transport can include questions about transpiration, its role in plant growth, and how it affects the environment.
In animals, transportation is mainly facilitated by the circulatory system, which includes the heart, blood vessels, and blood. The heart pumps blood throughout the body, delivering oxygen and nutrients to the cells and removing wastes. A worksheet for transport can cover topics such as the structure of the heart, the function of blood, and how the circulatory system helps maintain homeostasis.
Another important concept in transportation in animals and plants is the role of tissues that transport food and minerals. In plants, the xylem and phloem are responsible for transporting water, minerals, and sugars throughout the plant. In animals, the digestive system breaks down food into nutrients, which are then transported through the bloodstream to other parts of the body. A transportation worksheet can ask questions about the different types of tissues involved in transport and their functions.
To summarize, transportation in plants and animals is a fundamental concept in biology that class 7 students should be familiar with. A transportation worksheet for class 7 can help reinforce this knowledge by covering topics such as transpiration, the circulatory system, tissues that transport materials, and more. By using worksheets on transport, students can better understand the mechanisms of transportation in plants and animals and their importance to life.
Transportation in animals and plants class 7 extra questions and answers
Transportation in animals and plants refers to the movement of various substances like water, gases, and nutrients from one part of the organism to another.
The different modes of transportation in animals include diffusion, osmosis, active transport, and bulk flow.
Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.
Osmosis is the movement of water molecules from an area of higher water concentration to an area of lower water concentration across a selectively permeable membrane.
Active transport is the movement of molecules against their concentration gradient, i.e., from an area of lower concentration to an area of higher concentration with the help of energy.
Bulk flow is the movement of water and nutrients through long tubes in plants, like xylem and phloem, with the help of pressure differences.
Water is transported in plants through xylem, which is a specialized tissue that moves water from roots to leaves through a process called transpiration.
Transpiration is the process of water loss from plants through small pores called stomata present on the surface of leaves.
The circulatory system in animals is responsible for the transportation of blood and nutrients throughout the body.
Capillaries are small, thin-walled blood vessels that connect arteries and veins and allow for the exchange of gases, nutrients, and waste products between blood and tissues.
The main excretory product in humans is urine, which is formed in the kidneys and eliminated from the body through the urinary system.
The heart is a muscular organ that pumps blood throughout the body and ensures the proper functioning of the circulatory system.
The pulse is the rhythmic beating of the heart that can be felt in the arteries, and it indicates the rate and strength of the heart's contractions.
Dialysis is a medical procedure used to remove waste products from the blood when the kidneys are unable to function properly.
The function of the human excretory system is to eliminate waste products from the body, maintain the body's fluid balance, and regulate the levels of electrolytes in the blood.
Q: What is transportation in animals and plants? A: Transportation in animals and plants refers to the movement of materials such as nutrients, water, gases, and waste products within their bodies. This movement is essential for the survival and growth of both animals and plants.
Q: What are the modes of transportation in animals and plants? A: The modes of transportation in animals include circulatory system, respiratory system, and excretory system. The modes of transportation in plants include xylem and phloem.
Q: What is the circulatory system? A: The circulatory system is a network of blood vessels and organs that transport blood throughout the body of animals. The system is responsible for the distribution of oxygen, nutrients, and other essential substances to the body tissues, and removal of waste products from them.
Q: What is the respiratory system? A: The respiratory system is a network of organs and tissues that are responsible for the exchange of gases, primarily oxygen and carbon dioxide, between the body and the environment. In animals, the respiratory system includes the lungs, trachea, bronchi, and alveoli.
Q: What is the excretory system? A: The excretory system is responsible for the elimination of waste products from the body. In animals, the excretory system includes the kidneys, ureters, bladder, and urethra.
Q: What is transpiration? A: Transpiration is the process of water movement through a plant and its evaporation from aerial parts, mainly from the leaves but also from stems and flowers. It is an important mechanism for water transport in plants.
Q: What is xylem? A: Xylem is a specialized tissue in plants that is responsible for the transport of water and minerals from the roots to the other parts of the plant.
Q: What is phloem? A: Phloem is a specialized tissue in plants that is responsible for the transport of organic molecules, such as sugars and amino acids, from the leaves to other parts of the plant.
Q: How is food transported in plants? A: Food is transported in plants through the phloem, which carries sugars and other organic molecules from the leaves to other parts of the plant.
Q: How is water transported in plants? A: Water is transported in plants through the xylem, which carries water and minerals from the roots to the other parts of the plant.
Q: What is the difference between transport in animals and plants? A: In animals, transport occurs through specialized systems such as the circulatory, respiratory, and excretory systems. In plants, transport occurs through specialized tissues such as xylem and phloem.
Q: Why is transportation important in animals and plants? A: Transportation is important in animals and plants as it is essential for the distribution of essential substances such as nutrients and oxygen, and for the removal of waste products. It also plays a critical role in maintaining the water balance in both animals and plants.
