Prevents water Loss Allows Diffusion of Gases Q. Identify and label the following structures in the stomata diagram: guard cells, stomatal pore. Regulates the closing and opening of Stomata (amount of water) Controls Gaseous Exchange Traps light energy and converts it into usable chemical energy Engulfs Food Particles helps in Digesting the ingested food Q. a. Identify and label Stomach, Small intestine and Large intestine in the diagram and write functions. b. Also, label the structures in the digestive system where enzymes are secreted. Digestion begins here as salivary glands release Secretes Bile saliva which converts Starch into Maltose Bile emulsify fat globules Secretes HCl that kills bacteria & converts pepsinogen to pepsin Digestion completes here as intestinal Secretes : enzymes breakdown: Trypsin for Proteins PROTEINS - Amino acids Lipase for Fats CARBOHYDRATES - Glucose FATS -Fatty acids & glycerol Absorbs more water Q. Label the following parts of the human respiratory system on the diagram: Trachea, Lungs, Diaphragm, Bronchi, Bronchioles, Alveoli Also called as windpipe Junction of food pipe & + produces mucus wind pipe Prevents the walls of Trachea from collapsing Voice box Changes it shape to Exchange O2 & CO2 help thoracic cavity in the bloodstream expand (inhale) and contract (exhale) Figure 5.9 Human respiratory system Carry air from bronchi to alveoli Q. Draw and label the following parts of the human circulatory system on the provided diagram: a) Aorta, b) Pulmonary Artery, c) Pulmonary Vein, d) Left Atrium, e) Right Ventricle. Carries oxygenated blood from heart to body Carries deoxygenated blood from body to the lungs Carries deoxy. blood from body to heart Carries oxygenated blood from lungs to heart Receives deoxy. blood from body Receives oxygenated blood from lungs Receives deoxy. blood from Atrium Sends oxy. blood to Aorta Separates oxy. & deoxy. Figure 5.10 Schematic sectional view of Dicuspid Valve the human heart Tricuspid Valve Sends deoxygenated blood Receives oxygenated blood Carries deoxygenated Carries oxygenated blood blood Filters the blood collects blood to filter Helps in reabsorption of nutrients from filtrate passing through Helps in reabsorption of reabsorption of vital nutrients from filtrate nutrients passing through removes waste and extra fluid from body tube that carries urine from kidney to urinary bladder Store urines & empty urine under neuromuscular control Tube allows urine to pass outside the body Q. Identify and label part A,B and C acquires information impulse gets converted into a chemical signal A B C Figure 6.1 (a) Structure of neuron information travels as an electric impulse carry signal to the brain from receptors Allows sensory & motor nerves to communicate carry order from brain to effector body parts Q.A. Identify the labeled structure responsible for regulating basic bodily functions such as breathing, heart rate, and blood pressure. B. Name the part of the brain primarily associated with voluntary muscle movement and coordination. C. Which structure in the brain is responsible for processing sensory information such as touch, taste, and temperature? largest part of brain that controls body movements controls sleep cycle & body temperature Q. Label the part of Neuromuscular junction in diagram. Fig.6.1 Neuromuscular Junction allows the passage of pollens from female germ cell prepare ovules & protect developing zygote i.e. the fusion of male and female gametes Q. Label the parts in the Longitudinal section of a flower. produces pollen grains (male part of flower) contains ovules and each ovule has an egg cell (female part of flower) Q. Identify and label the following structures on the diagram: a) Ovary b) Fallopian tube (oviduct) c) Uterus d) Cervix e)Vagina passage for eggs of travel from ovary to uterus contains immature eggs passage through which sperms enter during intercourse produces semen (fluid that nourishes sperm cell) passage through which sperms travel ( testis to penis) formation of sperms Structure of S8 moleucle Electron dot structure of ethane Electron dot structure of ethene Electron dot structure of ethyne Refraction of light through a glass slab (a) A pattern of concentric circles (b) A close up of the pattern obtained indicating the field lines of a magnetic field around a straight conducting wire. The arrows in the circle shows the direction of the field lines. Field lines around a bar magnet
