Bryophytes can be separated from algae, because they
1 possess archegonia
2 contain chloroplast
3 are thalloid forms
4 have no conducting tissue
Explanation:
Bryophytes can be separated from algae, because they possess archegonia. Both algae and bryophytes have motive sperm and need water for fertilization, but bryophyte can be separated from algae because archegonia originated from the first time in bryophytes in plant kingdom. It is a flask shaped structure with swollen base called venter and upper elongated neck

Funaria gametophyte is
1 Dioecious
2 Heteroecious
3 Autoecious
4 Monoecious and autoecious
Explanation:
Funaria is both monoecious and autoecious, such that male and female reproductive structures develop on different branches of the same plant Autoecious means male \& female sex organs one found on the same plant but one on different branches (green photosynthetic).

In bryophytes, the posterior part of archegonium grows to protect the embryo. It is
1 paraphysis
2 apophysis
3 hypophysis
4 calyptras
Explanation:
Calyptra is the layer of cells that develop from the posterior part of the archegonium and covers the developing sporophyte of mosses and liverworts. Calyptra is a small, maternal gametophytic structure that covers the apex of the offspring sporophyte and is critical for the transition from seta formation to capsule differentiation in many moss taxa.

Select the correct statements A. In liverworts, mosses and ferns gametophytes are free living B. Sporophyte in mosses are more elaborate than in liverworts C. In Gymnosperms and Angiosperms gametophytes are independent D. Pinus and Cycas are dioecious
1 $\mathrm{A}$ and $\mathrm{C}$ are correct
2 $\mathrm{A}$ and $\mathrm{B}$ are correct
3 A, B and C are correct
4 A, B, C and D are correct
Explanation:
In mosses, liverwort, and ferns gametophyte are free living. and sporophyte of mosses are more developed than liverworts. Mosses gametophytes leafy and sporophyte have capsule on the end of stalk (setae). gametophyte of liverwort have leaves without midrib (costa) and leaves inserted at angle to stem. sporophyte has a transluscent stalk, capsule black and egg shaped.
