Match the right example of modified root

Modified root	Example

A.	Storage Root	Rhizophora

B.	Respiratory Root	Carrot

C.	Prop root	Maize

D.	Stilt root	Banyan Root

Options:
A A: Carrot; B-Rhizophora; C: Banyan; D: Maize
B B: Carrot; A-Rhizophora; C: Banyan; D: Maize
C A: Carrot; C-Rhizophora; B: Banyan; D: Maize
D A: Carrot; B-Rhizophora; D: Banyan; C: Maize

The correct answer is:
A: Carrot; B-Rhizophora; C: Banyan; D: Maize

Solution:
Roots in some plants change their shape and structure and become modified to perform functions other than absorption and conduction of water and minerals. They are modified for support, storage of food and respiration. Tap roots of carrot, turnip and adventitious roots of sweet potato, get swollen and store food. The hanging roots of banyan are called prop roots. Similarly, the stems of maize and sugarcane have supporting roots coming out of the lower nodes of the stem. These are called stilt roots. In some plants such as Rhizophora growing in swampy areas, many roots come out of the ground and grow vertically upwards. Such roots, called pneumatophores, help to get oxygen for respiration.

Solution:
Zygotene:

Chromosomes start pairing together. This process is called synapsis. The paired chromosomes are called homologous chromosomes.

The formation of synapsis is accompanied by the formation of the synaptonemal complex.

The synaptonemal complex by a pair of homologous chromosomes is called a bivalent or a tetrad.

Pachytene:

Bivalent chromosomes clearly appear as tetrads, at this stage.

Recombination nodules appear. These nodules are the sites at which crossing overtakes place between non-sister chromatids of the homologous chromosomes.

The exchange of genetic materials between two homologous chromosomes takes place during crossing over. This leads to the recombination of genetic materials on the two chromosomes.

Diakinesis:

Chiasmata is terminated at this stage.

Meiotic spindles are formed to prepare the homologous chromosomes for separation.

The nucleolus disappears and the nuclear envelope breaks down by the end of diakinesis.

Metaphase I:

The bivalent chromosomes are aligned on the equatorial plate.

Spindle fibres from opposite poles attach to the pair of homologous chromosomes.

This is carried out by the alimentary canal and it also includes many associated glands. Stomach is a J-shaped organ that brings about digestion of proteins only. In humans, the mouth consists of teeth and tongue. Human dentition is diphyodont (as there are two sets of teeth seen), heterodont (all teeth are of various shapes) and thecodont (as the teeth are embedded in the alveolar sockets). The alimentary canal consists of four walls. The outermost wall is the serosa which is absent in oesophagus.

(i) Light can be totally internally reflected when it passes from B to A

(ii) Light can be totally internally reflected when it passes from A to B

(iii) Critical angle for total internal reflection is iB-iA

(iv) Critical angle between A and B is sin-1â¡sinâ¡iAsinâ¡iB

Options:
A (i) and (iii)
B (i) and (iv)
C (ii) and (iii)
D (ii) and (iv)

The correct answer is:

Solution:
From Snell's law
μ=1sin⁡iC
Since, iB >iA
sin⁡i:B>sin⁡iA
⇒μB<μA
When angle of incidence in the denser medium is increased even very slightly beyond the critical angle, then the ray of light is reflected back completely in the denser medium and total internal reflection takes place. Let θ be critical angle from medium A to B, then
BμA=1sin⁡θ
⇒sin⁡θ=1 BμAμBμA

Mature male gametophyte of Angiosperm shows:

Options:
A 7 celled, 8 nucleate condition
B 8 celled, 7 nucleate condition
C 3 celled condition
D 6 celled condition

The correct answer is:
3 celled condition

Solution:
The pollen grains represent the male gametophytes. Pollen grains are shed at two-celled condition (a vegetative cell and a generative cell). The generative cell divides and forms the two male gametes during the growth of pollen tube in the stigma. In plants which shed pollen in the three-celled condition, pollen tubes carry the two male gametes from the beginning. Thus mature male gametophyte is a 3 celled structure.

B (P): blue light and (Q): blue light
C (P): blue light and (Q): red light
D (P): red light and (Q): blue light

The correct answer is:
(P): blue light and (Q): red light

Solution:
If we observe the absorption spectrum of chlorophyll-a, there is a large peak in the blue region while a smaller peak in the red region. Thus, maximum absorption by chlorophyll-a is seen in blue light. If we observe the action spectrum, we see that the maximum rate of photosynthesis is seen in red light. Thus, red light is better for photosynthesis.
