Find the wrong statement from following w.r.t liverworts :-Asexual reproduction takes place by gemmaeSpore germination is direct methodThe sporophyte differentiate into foot, seta and capsuleLeafly members have tiny leaf like appendages in two rows on true stems
Solution
To find the wrong statement regarding liverworts, let's analyze each statement one by one:
-
Asexual reproduction takes place by gemmae: This statement is correct. Liverworts can reproduce asexually through gemmae, which are small, multicellular structures that detach from the parent plant and develop into new individuals.
-
Spore germination is a direct method: This statement is incorrect. In liverworts, spore germination is an indirect method. The spores are released from the capsule of the sporophyte and develop into a gametophyte, which is the dominant stage in the liverwort life cycle.
-
The sporophyte differentiates into foot, seta, and capsule: This statement is correct. The sporophyte of liverworts consists of a foot, seta (stalk), and capsule. The foot anchors the sporophyte to the gametophyte, the seta elevates the capsule, and the capsule contains the spores.
-
Leafy members have tiny leaf-like appendages in two rows on true stems: This statement is correct. Leafy liverworts, also known as foliose liverworts, have tiny leaf-like appendages arranged in two rows on their true stems.
Therefore, the incorrect statement regarding liverworts is: "Spore germination is a direct method."
