FAQs on Important Diagrams: Life Processes - Science Class 10

1. What is the structure of stomata and how do they function in plants?
Ans. Stomata are small pores found on the surface of plant leaves that allow for the exchange of gases. They are made up of two specialized cells, known as guard cells, that control the opening and closing of the pore to regulate the movement of gases such as carbon dioxide and oxygen.
2. How does the human digestive system work to break down food for absorption of nutrients?
Ans. The human digestive system involves a series of organs, including the mouth, esophagus, stomach, and intestines, that work together to break down food into smaller molecules. Enzymes and acids help to further break down food into nutrients that can be absorbed by the body for energy and growth.
3. What is the process of gas exchange in the lungs and how does it support respiration?
Ans. Gas exchange in the lungs occurs in the alveoli, tiny air sacs where oxygen from the air we breathe enters the bloodstream and carbon dioxide is removed. This exchange of gases is essential for respiration, as oxygen is needed for cellular respiration and carbon dioxide is a waste product that needs to be removed from the body.
4. How does the human excretory system function to remove waste products from the body?
Ans. The human excretory system consists of the kidneys, ureters, bladder, and urethra, which work together to filter waste products from the blood and eliminate them from the body as urine. The kidneys filter blood to remove waste products, excess water, and electrolytes, which are then excreted as urine through the bladder.
5. What is the role of the human heart in the circulatory system and how does it function to pump blood throughout the body?
Ans. The human heart is a muscular organ that acts as a pump to circulate blood throughout the body. It consists of four chambers - two atria and two ventricles - that work together to receive oxygen-poor blood, pump it to the lungs for oxygenation, and then pump oxygen-rich blood to the rest of the body. This continuous circulation of blood is essential for delivering oxygen and nutrients to cells and removing waste products.
