Important Questions from JKBOSE class 10th Biology

Q.1 What is the process of photosynthesis?

Ans: Photosynthesis is the process by which green plants and some other organisms convert light energy into chemical energy in the form of glucose. This process occurs in the chloroplast of plant cells and involves converting carbon dioxide and water into glucose and oxygen through the action of chlorophyll pigments.

Q.2. What is the role of Enzymes in digestive action? 

Ans: Enzymes are essential for the process of digestion because they catalyze the breakdown of large molecules of food into small molecules that can be easily absorbed by the body. Enzymes such as amylase, lipase, and protease break down carbohydrates, fats, and proteins into their small components, respectively, which allow their absorption and use by the body. Without enzymes the process of digestion will be much slower and less efficient.

Q.3 What is the role of hormones in control and coordination in animals?

Ans: Hormones play an important role in the control and coordination of animals by regulating various physiological processes such as growth and development, metabolism, and reproductive functions. They act as chemical messengers that are secreted by the glands and travel through the bloodstream to target cells and organs triggering specific reactions. For example, the hormone regulates blood sugar levels by promoting glucose uptake by insulin cells, While hormone adrenaline increases heart rate and blood pressure during stress or exercise.

Q.4 How does the nervous system coordinate and control the movement of skeletal muscle in animals?

Ans: The nervous system coordinates and controls the movement of skeletal muscle in animals through the use of nerve impulses. Neural impulses are electrical signals that travel along nerve fibers and are generated by the brain and spinal cord. When a nerve impulse reaches a skeletal muscle it causes the muscle to contract resulting in movement. The nervous system also controls the timing and sequence of muscle contraction to coordinate movement. For example the brain sends signals to various muscle groups to coordinate arm and arm movements during writing.

Q.5 How do asexual reproduction occur in organisms?

Ans: Asexual reproduction is a type of reproduction that occurs without the involvement of meiosis or fertilization. In asexual reproduction an organism produces offspring that are genetically identical to themselves. This can happen through processes such as binary fragmentation, budding, fragmentation and vegetative reproduction. In binary fragmentation, the organism is divided into two identical copies. A small outbreak occurs on the original organism when budding which eventually separates and develops into a new organism. In fragmentation the original organism breaks down and each piece develops into a new organism. In botanical reproduction, the original organism produces special structures such as roots, stems, or leaves that can develop into new individuals.

Q.6 How do sexual reproduction occur in  organisms?

Ans: Sexual reproduction is a type of reproduction that involves fusion of gametes that are specialized reproductive cells that contain half the number of chromosomes as the parent organism. In animals gametes are called sperm and eggs. The gametes in plants are called pollen and seedand. Genetic material from sperm and eggs during sexual reproduction combine to form a new organism with a unique combination of genetic traits. This process is called fertilization. The new organism also receives half of its genetic information from each parent which leads to greater genetic diversity among offspring. Meiosis is the process of cell division that produces gametes.

Q.7 What is the difference between genes and alleles? 

Ans: A gene is a segment of DNA that codes for a specific feature or feature such as eye color or height. An allele is a type of a gene that means it may have different forms of the same trait such as brown eyes or blue eyes.

Q.8 What is the difference between Dominant and Recessive genes? 

Ans: Domanent genes are genes that will always express their characteristic when present regardless of the presence of other genes. Recessive genes on the other hand will express their characteristic only when paired with another recursive gene of the same trait. For example, the gene is predominant for brown eyes while the gene for blue eyes is recursive. If a person has a major gene for brown eyes and a recessive gene for blue eyes, their eyes will be brown.

Q.9 What are the causes of air pollution? 

Ans: The main causes of air pollution include industrial emissions, vehicle exhaust, burning of fossil fuels, deforestation and agricultural practices.

Q.10 What are the effects of water pollution on aquatic life? 

Ans: The effects of water pollution on aquatic life can be severe and may include reduction in oxygen levels, damage to the reproductive system and death. It can also lead to extinction of some species and disintegration of entire ecosystems.
