Question

1. Name the balloon like structure present in lungs.
2. How does the transport of materials in xylem and phloem occurs.
3. Name the respiratory pigment I'm human beings. where is this found.
4. What are raw materials essential for process photosynthesis ? Name by products and write Balance chemicl equation. ​

Answer 1

Answer:

1. Alveoli is balloon like structure present in lungs It's function is to exchange 02 and CO2 from the bloodstream.

2.Water is transported upwards from roots to all other plant parts. Food is transported in both upward and downward directions. Transport in xylem occurs with the help of simple physical forces such as transpiration pull. Transport of food in phloem requires energy in the form of ATP.

3. Haemoglobin is the name of the respiratory pigment in humans and it is found in our blood.

4.The raw materials required for this process are carbon dioxide and water in the presence of sunlight and chlorophyll.The complete balance equation of photosynthesis is

6 CO2 + 6 H20 + C6H1206 + 6 02

The byproduct in this reaction is molecular oxygen.

Answer 2

$\purple{\underline{\huge \sf Answers :}}$

1. The balloon like structures present in lungs are known as Alveoli. They contains an extensive network of blood vessels which exchange gases.

2. Xylem :

Xylem tissue transports water. Water is transported upwards from roots to upper parts or we can say aerial parts of plants by transpiration pull.

Phloem :

Phloem tissue transports food. Food is transported from leaves to all parts of plants by using energy from ATP.

3. Haemoglobin is respiratory pigment. This is present is red blood cells of blood. Haemoglobin has very high affinity for oxygen.

4. Raw materials essential for photosynthesis are Carbon dioxide, water, chlorophyll and in the presence of sunlight.

By products of above process is evolution of oxygen.

Chemical equation is :

$\sf 6CO_{2} + 6H_{2}O \longrightarrow C_{6}H_{12}O_{6} + 6O_{2}$
