Q. Read carefully the following statements I. $Funaria$ possesses unicellular and unbranched rhizoids II. Gemmae are asexual buds, which originate from small receptacles called gemma cups III. The $Sphagnum$ plants have magnificent property of retaining water IV. Mosses along with lichens are the first organisms to colonise rocks Which of the statements given above are correct?
A) I, II and III
B) I, III and IV
C) II, III and IV
D) I, II, III and IV
Explanation
The rhizoids in Funaria arise from the basal region of the stem, which functions as roots. These are multicellular and branched. The gemmae are multicellular, green and biconvex lens shaped bodies produced in gemma cup. Sphagnum is used as a packing material in the transportation of flower, live plants, tubers, bulbs seedlings, etc. It is also used in seed-beds and in moss-sticks. Mosses colonise on barren rocks along with lichens decompose rocks
