The plant body of bryophytes is attached to substratum with the help of
1 Unicellular or multicellular root
2 Unicellular or multicellular rhizoids
3 Multicellular rhizoids only
4 Unicellular rhizoids only
Explanation:
Unicellular or multicellular rhizoids can be found in Bryophytes. They help in the attachment of plant body to the substratum.

Sporophyte of bryophytes is I. Multicellular body II. Dependent on the gametophyte III. Some cells of the capsule undergoes reduction division to form spores IV. Non-dependent on the gametophyte
1 I, II and III
2 III and IV
3 Only I
4 All of these
Explanation:
The sporophyte in bryophytes is a multicellular body formed by division in zygote. It is not free-living and depends on the gametophyte. The cells in capsule of sporophyte undergo division to form spores.

Moss peat is used as a packing material for sending flowers and live plants to distant places because-
1 It is easily available
2 It is hygroscopic
3 It reduces transpiration
4 It serves as a disinfectant
Explanation:
Species of Sphagnum, a moss, provide peat that have long been used as fuel, and as packing material for trans-shipment of living material because of their capacity to hold water (hygroscopic).

3 Mode of nutrition
4 Multiplication by fragmentation
Explanation:
Multicellular fungi, filamentous algae and protonema of mosses multiply by fragmentation.
