Cycas and Adiatum resemble each other in having:-
1 Cambium
2 Vessels
3 Seeds
4 Motile sperms
Explanation:
Cycas and Adiatum both a have muticilliated motile sperm. - Adiatum also known as walking fern or maiden hair fern is a pteridophyte resembles with cycas. - Nacked seed, cambium is usual in gymnosperms and lack in pteridophyte - True vessels are lacking in both gymnosperm and pteridophytes. Adiatum known as a single hair fern - Cycas plants are dioecious belong from family cycadaceae.

Cycas have two cotyledons but not included in angiosperms becuase of : -
1 Naked ovules
2 Seems like monocot
3 Circinate ptyxis
4 Compound leaves
Explanation:
Cycas possesses naked seed (i.e. seed is not enclosed inside fruit). Cycas belongs to the order cycadaly of gymnosperm. In cyas there is no double fertilization, so the endosperm produced is haploid rather than triploid. So, it is not included in angiosperms as they have ovules (or seeds) produced 46 inside fruit. This is the main difference between gymnosperms and angiosperm.

The gametophyte is not an independent, free living generation in :
1 Pinus
2 Polytrichum
3 Adiantum
4 Marchantia
Explanation:
In Gymnosperms (like pinus), the main plant body is sporophyte. Sporophytic generation (diploid) is dominant \& independent. It greatly exceeds the reduced and dependent gametophyte generation (haploid). - Pinus have needle - shaped leaf that remain on the trees throughout the whole year (evergreen plants). Pinus is a monoecious plant, which means that one plant produces individual male and female cones. Note:- - Adiantum belong to the group ferns - Marchantia is a member of the group liverworts. - Polytrichum is a member of the group moss.

A prokaryotic autotrophic nitrogen fixing symbiont is found in
1 Pisum
2 Alnus
3 Cycas
4 Cicer
Explanation:
Symbiont means two organism living together. In case of cycas plant have a special type of root known as coralloid root. - Coralloid roots are formed soon after the primary root. Function of this root is $\mathrm{N}_{2}$ fixation because of presence of cyanobacteria (a member of blue green algae).

False statement related to Cycas is
1 Motile male gametes and pollen tubes are involved in fertilization
2 Endosperm formation occurs before fertilization
3 Ovule contains pollen chamber
4 Gametophytic tissue is not found in seeds
Explanation:
Gametophytic tissue (endosperms) is found in Cycas Seed. Cycas are dioecious plants with separate male and female plant and fertilization is effected by motile male gametes so called Zooidogamous reproduction. The endosperm in cycas is a haploid gametophytic tissue formed before fertilization. Cycas ovule contains pollen chamber in which pollen grains are stored after pollination.
