(d)


Question-5

Brown algae is characterised by the presence of

(a)

(b)

(c)

(d)

Explanation:

Answer: (b)

Brown algae are the members of the Class Phaeophyceae. Their chromatopores are ellipsoidal or discoid. They contain chlorophyll a, chl c, b- and c-carotenes and xanthophyll pigments (e.g., lutein, flavoxanthin, violaxanthin). They also contain large amount of a brown pigment – fucoxanthin which masks the green colour of chlorophyll pigment. This gives characteristic brown colour to these plants, hence the name brown algae.


Question-6

Male sex organ in angiosperm is located in

(a)

(b)

(c)

(d)


Question-7

The natural system of classification for flowering plants was given by

(a)

(b)

(c)

(d)

Explanation:

Answer: (a)

The natural system of classification for higher plants was given by Bentham and Hooker in their Genera Plantarum (1862 - 1883). The characters employed in this system include those of study of form (morphology), internal structure (anatomy), development (embryology), reproduction, cell structure (cytology), life processes, (physiology), behaviour and biochemistry.


Question-8

The endosperm of gymnosperm is

(a)

(b)

(c)

(d)

Explanation:

Answer: (d)

The endosperm of gymnosperms is haploid. It is a pre-fertilisation tissue and is equivalent to female gametophyte, hence it is haploid but in angiosperms, it is post-fertilization tissue and is generally triploid.


Question-9

When both the phases of life cycle are multicellular, i.e., haploid and diploid phases are more than one celled

(a)

(b)

(c)

(d)


Question-10

Bryophytes are found in

(a)

(b)

(c)

(d)


Question-11

Read the following statements (A-E) and answer the question which follows them.
  1. In liverworts, mosses and ferns gametophytes are free-Living
  2. Gymnosperms and some ferns are heterosporous.
  3. Sexual reproduction in Fucus,Volvox and Albugois oogamous
  4. The sporophyte in liveworts is more elaborate than that in mosses
  5. Both, Pinus and Marchantia are dioecious
How many of the above statements are correct?

(a)

(b)

(c)

(d)

Explanation:

Answer: (a)

In liverworts and ferns gametophytes are free living while in fern, sporophytes are free living. Gymnosperms and genera like Selaginella and Salvinia are heterosporous. The sporophyte in mosses are more elaborate than that of liverworts, Pinus is monoecious and heterosporous. Marchantia is dioecious.


Question-12

Consider the following statements regarding gymnosperms and choose the correct option.
  1. In gymnosperms, the male and female gametophytes have an independent existence.
  2. The multicellular female gametophyte is retained within the megasporangium.
  3. The gymnosperms are heterosporous.
Of these statements

(a)

(b)

(c)

(d)

Explanation:

Answer: (d)

In gymnosperms, the male and female gametophytes never grow independently but develop within the sporophyte structures.


Question-13

Phylogenetic classification systems are based on—

(a)

(b)

(c)

(d)


Question-14

Multicellular branched rhizoids and leafy gametophytes are the characteristics of

(a)

(b)

(c)

(d)

Explanation:

Answer: (b)

The Division Bryophyta includes three classes Hepaticopsida, Anthocerotopsida and Bryopsida. The members of Hepaticopsida and Anthocerotopsida have a thallose plant body which is dorsiventrally differentiated and dichotomously branched. On the ventral surface unicellular or multicellular rhizoids are present. The member of Bryopsida have a main plant body that has a leafy gametophore made up of an axis having spirally arranged leaves. The rhizoids are multicellular and branched e.g. Sphagnum, Funaria, Riccia, Anthoceros. So only few member of bryophytes have leafy gametophytes.


Question-15

If the diploid number of a flowering plant is 36. What would be the chromosome number in its endosperm?

(a)

(b)

(c)

(d)

Explanation:

Answer: (c)

Endosperm is a product of triple fusion. One male nuclei (n = 18) fuses with diploid secondary nucleus (2n= 36), so it becomes triploid (3n = 54). Thus, ploidy of endosperm is (3n) and chromosomes will be 54.


Question-16

Which one of the following is the major difference between mosses and ferns?

(a)

(b)

(c)

(d)

Explanation:

Answer: (d)

Mosses and ferns belong to bryophtes and pteridophytes respectively. In bryophytes, the dominant phase in the life cycle is the gametophytic plant body. However, in pteridophytes, the main plant body is a sporophyte, which is differentiated into true root, stem and leaves. These organs possess well–differentiated vascular tissues.


Question-17

Protonema stage is found in

(a)

(b)

(c)

(d)


Question-18

In which of the following gametophyte is not independent free living?

(a)

(b)

(c)

(d)

Explanation:

Answer: (c)

Pinus belongs to gymnosperms in which male and female gametophytes do not have an independent free living existance. They remain within the sporangia which are of two types — microsporangia and megasporangia.


Question-19

Syngamy can occur outside the body of the organism in

(a)

(b)

(c)

(d)

Explanation:

Answer: (a)

Syngamy is the complete and permanent fusion of male and female gametes to form the zygote. When fertilization occurs outside the body of the organism, this type of gametic fusion is called external fertilization or external syngamy. In majority of algae, external fertilization occurs.


Question-20

Turpentine is got from

(a)

(b)

(c)

(d)

Explanation:

Answer: (c)

Resins and turpentine are obtained from Pinus which is gymnospermic plant.
