Test: On Killing A Tree - Class 9 MCQ

The poet uses the tree to symbolise both positive and negative aspects. It represents 'a good tradition' through its beauty and strength, while also embodying 'a deep-rooted evil' due to its association with suffering and oppression.

Therefore, the correct answer is 'all of the above.'

A single knife stab generally cannot kill a tree due to their robust structure and distributed vascular tissues. Significant damage or repeated stabs targeting critical areas are typically required.

Trees primarily consume water and nutrients from the soil, as well as carbon dioxide from the air and sunlight for photosynthesis. Since none of the options fully capture this, the correct answer is 'None of the above.'

Trees absorb sunlight for photosynthesis, carbon dioxide from the air, and water through their roots, all essential for growth.

• Trees absorb sunlight for photosynthesis.
• They take in carbon dioxide from the air.
• They absorb water through their roots.

Therefore, the correct answer is D, as trees absorb all of these elements.

The sun and the air harden and wither the exposed roots of the tree and kill it. The sun and the air are the two essential elements that help in the growth of a tree. Left to themselves, they will never kill a tree. But if the roots are exposed and kept in the sun and air, the tree will wither away and die.

To kill a tree by pulling out a part, you need to remove the root. Roots are essential for:

• Absorbing water from the soil
• Taking in nutrients necessary for the tree's survival

Without its roots, the tree cannot sustain itself and will die.

The strength of a tree lies in its roots because they provide essential functions. Roots anchor the tree, preventing it from being uprooted by strong winds or storms.

Additionally, roots absorb water and nutrients from the soil, which are vital for the tree's growth and survival. This dual role of anchorage and nutrient uptake makes the root crucial for the tree's overall strength and stability.

• Anchorage: Roots prevent the tree from being uprooted by strong winds or storms.
• Nutrient Absorption: Roots absorb water and nutrients from the soil, essential for growth and survival.

This dual role makes the root a crucial component for the tree's overall strength and stability.

Scorching is primarily caused by the intense heat emitted by the sun, leading to high temperatures that can burn or char surfaces.

The poem describes how a tree does not die just by cutting it down because new shoots will grow from the remaining stump. To completely kill a tree, its roots must be uprooted and exposed to air and sunlight. When the roots are exposed, the tree loses its source of nourishment, which is essential for its survival. The roots, being "the most sensitive, hidden" part of the tree, dry up when exposed to air, leading to the tree's eventual death.

The root remains hidden in the earth, where it can stay dormant for several years before regrowing when conditions become favourable. This is typical for perennial plants with structures like:

• Taproots – thick, fleshy roots that grow deep into the soil.
• Tubers – swollen underground stems that store nutrients.

These adaptations allow the plants to survive unfavourable periods underground.

Root death can occur due to various environmental factors. The two key issues associated with this phenomenon are:

• Scorching: This refers to damage from excessive heat or chemicals, which can harm root tissues.
• Choking: This often relates to physical blockages, such as soil compaction, preventing roots from functioning properly.

Therefore, both scorching and choking are related to root death.

When a tree's bark is injured and starts bleeding, the tree typically begins to heal gradually. This process involves the formation of callus tissue or scar tissue that covers the wound over time.

The healing rate depends on several factors, including:

• Severity of the injury
• Environmental conditions

Therefore, the most accurate answer is that it heals gradually over time.

Green twigs, when properly rooted through methods like grafting or using rooting hormones, can develop into a new tree that reaches the original's full size.

To kill a tree, one effective method is cutting down the trunk and allowing it to die over time. Alternatively, applying herbicide can also be used to kill the tree.

While pulling out the roots entirely would certainly kill the tree, it is not always necessary as other methods are more practical.

Here are the main methods to consider:

• Cutting down the trunk: This allows the tree to die naturally over time.
• Applying herbicide: A chemical method that can effectively kill the tree.
• Pulling out the roots: This is effective but not always practical.

The correct answer is Gieve Patel, as he is known for his modernist and intense poetic style, which aligns with the themes in 'On Killing a Tree.'
