Cones with out sporophylls are found in ____________.

  1. Lycopodium

  2. Psilotum

  3. Rhynia

  4. Equisetum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In Lycopodium, the sporangia are borne on the adaxial surface of sporophylls, but they are often described as being in cones where the sporophylls are modified, though the statement 'cones without sporophylls' is technically a misnomer or refers to specific morphological interpretations.

Consider the following statements.
a. In Pteridophytes, the phloem lacks companion cells
b. The xylem lacks vessels in majority of Pterifophytes
c. Heterosporous Pteridophytes have inconspicuous gametophytes
d. Water is essential for fertilization in Pteridophytes.
Which of these statements are correct?

  1. $1, 2, 3$ and $4$
  2. $2, 3$ and $4$
  3. $1$ and $3$
  4. $1, 2$ and $4$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

All four statements are correct: Pteridophytes lack companion cells, xylem vessels are generally absent (except in some Gnetales/Selaginella), heterosporous ones have reduced gametophytes, and water is required for fertilization.

You discover a new species of a plant. You discover that it produces motile sperms and dominant generation has diploid cells. It belongs to

  1. Bryophyte

  2. Angiosperm

  3. Gymnosperm

  4. Pteridophyte
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Amongst Bryophytes, Pteridophytes, Gymnosperms and Angiosperms, only bryophytes and pteridophytes produce motile sperms which swim in the surrounding medium to reach female gamete for the process of fertilisation. While. in pteridophytes only the dominant generation is diploid. The dominant generation in bryophytes is haploid.
So, the correct answer is 'Option D- Pteridophytes'.

If the root cell of a pteridophyte contains 10 chromosomes, then the chromosome number in indusium, sperm mother cell and spore mother cell are respectively.

  1. 10,5,10

  2. 10,5,5

  3. 10,10,10

  4. 5,10,10
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The root cell is diploid (2n=10). The indusium is part of the sporophyte (2n=10). The sperm mother cell is part of the gametophyte (n=5). The spore mother cell is part of the sporophyte (2n=10).
