VIII. Answer in detail
1 Write short notes on – Timber yielding plants.
The wood needed for the construction of buildings and making of furniture are obtained from certain plants. We use these woods for their features like durability, stylish finishing and resistance to temperature changes.
All commercial timbers are classified into Hardwood and softwood
Hardwood
Hardwoods are angiosperm i,e flowering plants.
High-quality furniture, desks, flooring, and wooden construction are being made only using hardwood.
Eg. Teak, Jackfruit.
Softwood
Softwoods are gymnosperm i.e. non-flowering plants
Certain angiosperms also yield softwood. Softwoods have a wide range of applications such as making plywood, wooden boxes, medium-density Fibreboard (MDF) and paper making.
Eg: katampu,Pine
2. Comment on importance of plant animal interaction.
1.Animals rely on plants for their food and shelter. This relationship benefits not only animals but also plants. Such a relationship is economically significant.
Silkworms feed on mulberry leaves and live on mulberry plants.
2.Bright colours of flowers, smell and honey attract insects. As the insects go from one flower to another, they leave the pollen grains from their body. This results in cross-pollination and the formation of vegetables and fruits.
These insect pollinators and birds need to be protected to produce the best yield.
Bees are the best pollinators. They also give us honey.
3. Plants and algae living in coral reefs are the food for a variety of fishes.
4. Animals and birds play an important role in spreading seeds of various plants.
The digestive enzymes in the digestive system of the birds soften the protective layer of the seeds and make it easier to germinate.
IX. Questions based on Higher Order Thinking Skills
1. Desert does not have water. Why? Give the reason.
A desert is an area of land that receives only less than 25 centimeters of rainfall in a year. The amount of evaporation in a desert is often greater than the annual rainfall. Hence, in all deserts, there is little water available for plants and other organisms.
2. Kavitha said “ Palm tree is a tall tree, so it gives hard wood”! Do you agree with her statement or not ? Explain Why?
No. I do not agree with her.
Palm trees are neither hardwood or softwood.In fact a palm tree is not really a tree but is a grass much like sugar cane,and rice and therefore technically doesn’t grow any wood.
3. Look at the diagram given below and answer the following questions.
a. Soil fertility is increased by bacteria How?
Bacteria help fix the atmospheric nitrogen and increase the nitrogen content in the soil. It is referred to as Nitrogen-fixing Bacteria.
Eg. Anabaena, Azotobacter, etc
b. Honey bees are essential for the reproduction of the plants Why?
Most flowering plants require a pollinator to transfer pollen from the anther of one plant to the stigma of another.
Between 74% and 94% of plants all over the world that produce flowers rely on pollinators.
The most important kinds of pollinators are bees, specifically honeybees.
There are more than 450 kinds of bees in the world.
Hence, honey bees are essential for the reproduction of the plants.
