Answer 1

Answer:

1. Arteries and, Veins.

2. Alveoli.

3. Photosynthesis.

4. Nephrons.

Explanation:

1. Arteries carry oxygenated blood from heart to different body parts except Pulmonary artery and Veins carry deoxygenated blood from different body parts to the heart except Pulmonary vein.

• Arteries are also known as distributing vessel. It's walls are thick, elastic and mascular.
• Veins are also known as collecting vessel. Its walls are thin, less elastic and non muscular.

2. Alveoli contains an exclusive network of blood vessel which exchange gases.

• Alveoli are balloon like structure. They present in lungs. They are sites of exchange of gases.

3. Green plants manufacture their food by the process of Photosynthesis.

• In photosynthesis, plants make their food by taking carbon dioxide through stomata, water from roots, light energy from chloroplast (It store energy of sunlight) and by chlorophyll.

4. Nephrons are the basic filtration units of kidneys.

• Nephrons carry out filteration, selective reabsorption and tabular secretion to form urine. They are made up of glomerulus (Made up of thin capillaries).

Answer 2

1. Arteries and Viens

2. Alveoli

3. Photosynthesis

4. Nephrons
