Test: Transport of Substances in Animals and Plants - Class 7 MCQ

Transpiration is a process by which water is lost from the leaves of plants and is not a method of transport.

Air is not a substance that needs to be transported in animals and plants, as they rely on respiratory organs for oxygen intake.

Blood vessels transport oxygenated blood from the lungs to the body cells, where it is utilized for cellular respiration.

Xylem is a specialized tissue that transports water and minerals from the roots to the leaves in plants.

Photosynthesis is a process that occurs only in plants, and is not a method of transport in animals.

Phloem is a specialized tissue that transports food from the leaves to the other parts of the plant, such as the roots and stem.

The kidneys are responsible for the removal of metabolic waste from the body in animals, through the production of urine.

The circulatory system in animals is responsible for the transportation of nutrients, waste products, and oxygen, but is not involved in the production of hormones.

Stomata are small pores on the surface of leaves that are responsible for the exchange of gases, such as oxygen and carbon dioxide.

Chloroplasts are organelles found only in plants, and are not a component of blood in animals.

Muscle tissue is a type of tissue in animals that is responsible for the contraction and relaxation of muscles.

Maintaining body temperature is not a function of transport in animals. This is the job of the thermoregulatory system.

To carry oxygen. Red blood cells contain a protein called hemoglobin, which binds with oxygen and transports it to different parts of the body.

While the kidneys are an important component of the excretory system, they are not directly involved in the transport of substances in the circulatory system.

To transport water and minerals from the roots to the leaves. Xylem is a type of tissue in plants that is responsible for transporting water and minerals from the roots to the rest of the plant.

By increasing blood flow to the skin. When the body needs to cool down, the circulatory system increases blood flow to the skin, allowing heat to be released through the skin's surface.

To transport sugars from the leaves to the rest of the plant. Phloem is a type of tissue in plants that is responsible for transporting sugars and other organic compounds from the leaves to the rest of the plant.

Animals need to transport a variety of substances, including gases like oxygen and carbon dioxide, nutrients like glucose, and other molecules like hormones and waste products.

Chloroplasts are an organelle found in plant cells that are responsible for photosynthesis, but they are not present in animal blood.

The circulatory system in animals is responsible for a variety of functions, including the transport of oxygen and nutrients, the removal of waste products, and the regulation of body temperature.
