Heterosporous pteridophyte includes both:

1. Lycopodium and Equisetum

2. Selaginella and Salvinia

3. Psilotum and Phylloglossum

4. Selaginella and Equisetum

The life cycle is not haplo-diplontic in:

1. Bryophytes

2. Pteridophytes

3. Polysiphonia

4. Fucus

Asexaul reproduction by pear shaped biflagellate zoospores is seen in most:

1. Green algae

2. Brown algae

3. Red algae

4. Both (2) and (3)

All the following pteridophytes belong to the Class Pteropsida except:

1. Dryopteris

2. Pteris

3. Selaginella

4. Adiantum

Sexual reproduction by non-flagellated but similar in size gametes is seen in:

1. Chlamydomonas

2. Volvox

3. Spirogyra

4. Fucus

In mosses, the sex organs are seen in:

1. Protonema stage

2. Leafy stage

3. Capsule of the sporophyte

The features seen in the gymnosperm Cycas include:

I. Coralloid roots

II. Unbranched stems

III. Pinnate persistent leaves for a few years

IV. Male cones and megasporophyllys borne on same plant

1. I and II only

2. I and IV only

3. I, II and III only

4. I, II, III, and IV

Both bryophytes and pteridophytes:

1. are vascular cryptogams

2. have a dominant sporophyte

3. reproduce only sexually

4. are haplo-diplontic
