  1. Psilotum, Lycopodium, Pteris and Adiantum

  2. Selaginella, Salvinia, Lycopodium and Pteris

  3. Salvinia, Lycopodium, Selaginella and Psilotum

Correct Option: A

In fern sex organ are found on :-

  1. Protonema

  2. Prothallus

  3. Sporophyte

  4. Sporophyll


Correct Option: B
Explanation:

The antheridium (male organ) is located on the lower surface of the fern prothallus and the archegonium (female organ) is located on the upper surface of the fern prothallus.

So, the correct option is 'prothallus'.

Vascular cryptogams are

  1. Pteridophytes

  2. Angiosperms

  3. Mosses

  4. Algae


Correct Option: A
Explanation:

Cryptogams are defined as lower plants or plant-like organisms, that reproduce by spores. Vascular Cryptogams refers to those vascular plants, that do not make seeds.

Which statement is correct for homosporus pteridophyta ?

  1. Gametophyte is autotrophic, whille sporophyte is parasitic

  2. Gametophyte is semi parasite and sporophyte is autotrophic

  3. Gametophyte and sporophyte are usually parasitic

  4. Sporophyte is autotrophic


Correct Option: A

The plants with primitive vascular tissue are called

  1. Bryophytes

  2. Pteridophytes

  3. Angiosperms

  4. Gymnosperms


Correct Option: B
Explanation:
A. Bryophytes are the first land inhabiting or terrestrial plants. They are non vascular, terrestrial, non-flowering and non-seeded plants.
B. Pteridophytes are also known as vascular cryptograms. They are seedless vascular plants which have vascularised root, stem and leaves. 
C. Gymnosperms are the naked seeded plants.
D. Angiosperms are seed bearing and flowering vascular plants which have their seeds enclosed in fruits.
Hence, plants with primitive vascular tissue are called Pteridophytes.
So, the correct answer is 'Pteridophytes'.

The pteridophyte, popularly known as 'horsetail' or a 'scouring rush' is

  1. Equisetum

  2. Fern

  3. Lycopodium

  4. Psilotum


Correct Option: A
Explanation:

Horsetail is in a family of plants containing about 35 species within the genus Equisetum. Scouring rush (Equisetum hyemale) is evergreen, with leafless, hollow, segmented stems with ash-colored bands. Stems grow to about 1/2 inch in diameter and reach up to five feet tall. Because the stems are rough and durable (due to their high silica content), they were called as scouring rushes, because early pioneers used them to scrub pots and pans. 

Which group of plants is called as vascular cryptogams?

  1. Pteridophyta

  2. Bryophytes

  3. Algae

  4. Fungi


Correct Option: A
Explanation:

Vascular cryptogam is an old botanical phrase and it refers to those vascular plants that do not make seeds. Thus, cryptogam refers to the production of a separate, usually very small, archegoniate gametophyte. These are well represented in the fossil record.

Thus, vascular cryptogams are pteridophytes.
