Which function(s) of the tree is/are hampered by debarking?
Debarking removes the bark, which protects the tree from injury, microorganisms and water loss. It can also damage phloem tissue present beneath the bark, disturbing transport of food from leaves to roots and storage organs. As a result, nutrition, growth and survival of the tree become affected, esRead more
Debarking removes the bark, which protects the tree from injury, microorganisms and water loss. It can also damage phloem tissue present beneath the bark, disturbing transport of food from leaves to roots and storage organs. As a result, nutrition, growth and survival of the tree become affected, especially if a large area of bark is removed.

See lessWhich specialised tissue is responsible for the girth of the stem and where is it located?
The lateral meristem is responsible for the increase in girth or thickness of stems and roots. It is located along the circumference of these plant parts in the form of a ring of actively dividing cells. Continuous cell division by lateral meristem produces new tissues inward and outward, increasingRead more
The lateral meristem is responsible for the increase in girth or thickness of stems and roots. It is located along the circumference of these plant parts in the form of a ring of actively dividing cells. Continuous cell division by lateral meristem produces new tissues inward and outward, increasing stem diameter and forming annual growth rings in woody plants.

See lessWhich plant tissue would be affected by further damage to the tree trunk even after debarking?
Further damage to the tree trunk after debarking would mainly affect the phloem tissue located beneath the bark. Phloem carries prepared food from leaves to roots and other plant parts. Damage to this conducting tissue interrupts nutrient transport, reducing energy supply, weakening plant growth andRead more
Further damage to the tree trunk after debarking would mainly affect the phloem tissue located beneath the bark. Phloem carries prepared food from leaves to roots and other plant parts. Damage to this conducting tissue interrupts nutrient transport, reducing energy supply, weakening plant growth and eventually threatening the survival of the entire tree.

See lessSohan designed an experiment for the regeneration of sugarcane, where he used cuttings to grow sugarcane. He used two types of cuttings, type ‘A’ and type ‘B’ (Fig. 3.23). After a few weeks, type ‘B’ cuttings sprouted and developed into sugarcane plants, whereas the type ‘A’ cuttings did not sprout. (i) Why were the type ‘B’ cuttings able to grow as sugarcane but type ‘A’ could not? (ii) What difference was present in type ‘B’ compared to type ‘A’? (iii) What observation or measurement was made to determine whether this change had an effect? (iv) What parameters should be kept the same for both types of cuttings to ensure a fair comparison?
(i) Type B cuttings developed into sugarcane plants because they contained nodes with active intercalary meristem capable of cell division and regeneration. (ii) Type B had buds or nodes, unlike type A. (iii) Growth, sprouting and shoot formation were observed to measure effects. (iv) Soil type, watRead more

(iii) Growth, sprouting and shoot formation were observed to measure effects.
(iv) Soil type, water supply, sunlight, temperature, cutting size and growth duration should remain the same for fair comparison.

See lessAamrapali observed that a young mango sapling’s stem bends flexibly during monsoon winds and does not break. Which tissue is responsible for this flexibility? Predict and provide your explanation of the impact if the existing tissue was replaced by sclerenchyma.
The flexibility of the young mango sapling’s stem is due to collenchyma tissue, which has unevenly thickened walls containing pectin. This tissue provides support with flexibility, helping the stem bend during strong winds without damage. If sclerenchyma replaced collenchyma, the stem would become hRead more
The flexibility of the young mango sapling’s stem is due to collenchyma tissue, which has unevenly thickened walls containing pectin. This tissue provides support with flexibility, helping the stem bend during strong winds without damage. If sclerenchyma replaced collenchyma, the stem would become hard, rigid and brittle because sclerenchyma has thick lignified walls, making the sapling more likely to break.
