Question 1. Write a note on how forests influence the quality of our air, soil and water resources.
Answer.

Forests influence the quality of our air, soil and water resources as follows

Air:

• It helps in purifying the air by absorbing pollutants.
• It adds oxygen to the air and takes carbon dioxide gas during photosynthesis. Therefore, the greenhouse effect is controlled.
• Transpiration helps in the formation of clouds, it maintains the temperature of surrounding area and gives cooling effect.

Soil:

• Plants in forest hold the soil thereby preventing soil erosion.
• It holds the soil which helps in increasing the underground water level.
• Adds nutrients to the soil as lot of vegetation present in forest gets decomposed.

Question 3. How are living organisms dependent on the soil? Are organisms that live in water totally independent of soil as a resource?
Answer.

All living organisms are directly or indirectly dependent on soil. Plants obtain water and minerals from the soil and prepare food for themselves and animals. Other organisms that live in water are not totally independent of soil because the microbes growing on the soil in water are the primary producers in the soil which starts the food chain and even other microbes that live in soil helps in the decomposition of dead plants and animals in water to return the nutrients and other elements back to the water.

Question 5. How is soil formed?
Answer.

Formation Of Soil:

The factors that helps in the formation of soil and the process of formation are as follows.

• Sun: Sun heats up rocks during the day so that they expand. At night, these rocks cool down and contract, this causes cracks in the rocks.
• Water: Water during rainfall enter these cracks, if this water freezes, it exerts pressure on the cracks and the rocks break. When water flows, it wears the hard rock and carries small particles of rock down stream.
• Wind: Strong winds erode rocks down, which rubs with each other and small particles are carried away by wind.
• Living organisms: Organisms like lichen grows on the surface of the rock, they release certain substances that causes the rock surface to powder down and form a thin layer of soil.

Question 1. Thallophyta, Bryophyta and Pteridophyta are known as ‘Cryptogams’. Gymnosperms and angiosperms are called ‘phanerogams’. Discuss why?
Answer.

Thallophyta, Bryophyta and Pteridophyta are known as ‘Cryptogams’. Gymnosperms and angiosperms are called ‘phanerogams’.

Thallophyta, Bryophyta and Pteridophyta are called ‘Cryptogams’ because the reproductive organs of these groups are inconspicuous or hidden. Seeds are absent. On the other hand, ‘Phanerogams’ include gymnosperms and angiosperms which have well-differentiated reproductive tissue and the embryo with stored food. Embryo develops into seed

Question 2. Which organism is more complex and evolved among bacteria, mushroom and mango tree. Give reasons.

Answer.

The functions of lysosomes:

• Lysosomes act as intracellular digestive system by destroying any foreign material that enters the cell and hence, these are called digestive bags. By doing this, they protect the cells from any harmful effect of foreign material such as from bacterial infection.
• Lysosomes remove the worn out cellular organelles by digesting them so that new replacements are done. By doing this, they remove the cell debris. Thus, lysosomes act as a type of garbage disposal system of the cell. These are also known as demolition squads, scavengers and cellular housekeepers.
• At the time of breakdown of cell structure, lysosomes may burst and the enzymes released eat up their own cells. Thus, lysosomes are also known as suicidal bags of a cell.

Question 5. Discuss the functions and types of ribosomes.
Answer.

The functions and types of ribosomes:

• Function: Ribosomes play a crucial role in the synthesis of proteins. These are the factories of protein in a cell. One ribosome cannot perform protein synthesis. In 1963, Gric and Hall published the detailed role of polyribosome in protein synthesis and showed that active units are no individual ribosome, instead a group of these units are known as polyribosomes.
• Types of ribosomes: Basically, there are two types of ribosomes, such as 70S and 80S ribosomes. Here, S denotes Svedberg unit, which is the sedimentation coefficient that depicts how fast cell organelle sediments in an ultracentrifuge. Sedimentation coefficients cannot be additive.

Question 7. Discuss the structure of nucleus.
Answer.

The structure of nucleus:

The nucleus is membrane-bounded, centrally located, spherical structure present in the eukaryotic cell. There are two nuclear membranes forming a nuclear envelope. There is a space between two nuclear membranes, which is connected to a system of membranes known as endoplasmic reticulum (ER).

The nuclear envelope makes the nucleus distinct from the cytoplasm. It also contains many pores called nuclear pores and consists of the liquid ground substance called nucleoplasm. Nuclear pores permit the transfer of substances between the nucleoplasm and the cytoplasm.

The nucleoplasm consists of the nucleolus and chromatin material. The nucleolus is not bounded by any membrane, and is rich in protein and RNA (ribonucleic acid), and thus, it acts as the site for ribosome production. Ribosomes help in protein synthesis in the cytoplasm.
