Solution:
Rhizopus is a bread mould which has aseptate and coenocytic mycelium and belongs to phycomycetes. Penicillium has a septate and branched mycelium and belongs to ascomycetes, also called sac fungi. Ustilago or smut has a septate and branched mycelium and it belongs to basidiomycetes. Colletotrichum shows only the asexual phase. Hence, it belongs to deuteromycete or imperfect fungi.

Vasopressin is also known as anti-diuretic hormones as it reduces water loss through urine. ACTH, adrenocorticotropic hormone, which stimulates the secretion of the steroid hormones from the adrenal cortex. Oxytocin stimulates the smooth muscles in the body the uterus being one of them during childbirth. The growth of the mammary gland and milk secretion in them is regulated by the hormone prolactin. ICSH or the interstitial cells are responsible for testosterone production in males.

C a - ii, b - i, c - iii, d - iv
D a - i, b - ii, c - iv, d - iii

The correct answer is:
a - iii, b - iv, c - i, d - ii

Solution:
Eutrophication is the nutrient enrichment of water bodies containing an excessive population of phytoplankton. This leads to an overgrowth of flora and fauna in the water body until the organic deposition makes it warmer and shallower. Warm-water population increases and the final stage is its conversion into a land.
Sanitary Landfill is a method of solid waste disposal in which the waste material is buried in the pits dug on the ground and later they get covered by soil.
Snow blindness is caused due to UV-B radiations exposure. These radiations can reach the earth surface due to the depletion of the ozone layer.
In Jhum cultivation, the land is cultivated temporarily and then abandoned so that, it can revert to its natural vegetation. It is a long-term process and usually leads to deforestation.

D (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)

The correct answer is:
(a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)

Solution:
Mycorrhiza: This is a mutualistic relationship between fungi and roots of higher plants. Fungi absorb essential nutrients from the soil while the plants, in turn, provide energy-yielding carbohydrates to the fungi.

Competition in the broadest sense refers to the interaction of two organisms striving for the same resource. Sheep and cattle both are herbivores and fight for the same resource when present together. It is an example of an interspecific competition.

In predation, only one species (predator) benefits and the interaction is detrimental to the other species (prey). Herbivores are predators and plants are prey.

Epiphytes (orchids) growing on other plants like mango (host) gets benefit in the form of shelter but the host neither drives any apparent benefit nor does it get harmed. Such an interaction is called commensalism.

The ovule is a small structure attached to the placenta by means of a stalk called funicle. The body of the ovule fuses with funicle in the region called hilum. Thus, hilum represents the junction between ovule and funicle. Each ovule has one or two protective envelopes called integuments. Integuments encircle the nucellus except at the tip where a small opening called the micropyle is organised. Opposite the micropylar end is the chalaza, representing the basal part of the ovule.

D A - 1, B - 4, C - 3, D - 2.

The correct answer is:
A - 3, B - 2, C - 1, D - 4

Solution:
Calcium is required by the meristematic and differentiating tissues for cell wall formation as it is an important component of middle lamella as calcium pectate. It is also needed during for synthesis of the mitotic spindle. Necrosis refers to the death of tissues resulting in the deficiency of elements like calcium, magnesium, copper, potassium.
Delayed flowering results in the deficiency of elements like nitrogen, sulfur and molybdenum. Molybdenum is a component of various enzymes like nitrogenase and nitrate reductase (both involved in nitrogen metabolism).
Chlorine is absorbed along with Na+ and K+. It also determines the solute concentration and the anionâcation balance in cells. Mn, Cl and Ca are involved in the photolysis of water leading to oxygen evolution.
Iron is an important constituent of ferredoxin and cytochromes (proteins involved in the transfer of electrons). It is required in larger amounts in comparison to the other micronutrients. Chlorosis is the loss of chlorophyll leading to yellowing of leaves. Deficiency of elements nitrogen, potassium, magnesium, sulfur, iron, manganese, zinc and molybdenum causes chlorosis.

Solution:
- Carbon dissolved in oceans = About $71 \%$
- Annual fixation of $\mathrm{CO}_2$ through photosynthesis is $=4 \times 10^{13} \mathrm{~kg}$
- PAR captured by plants $=2-10 \%$
$$
\text { - Productivity of oceans }=55 \text { billion tonnes }
$$
