Q. 1. State the general features of the division Thallophyta as a whole. Enumerate in a tabulated form the differences between algae and fungi.

Ans. Thallophyta is one of the largest division of the plant kingdom. Thallophyta (thallos = a young shoot, phyton = a plant), include the simplest plants with undifferentiated thalli i.e., the plant body is not differentiated into root, stem, leaves. Some of the thallophytes are unicellular but the majority is multicellular. The multicellular forms vary in the size of the thallus, degree of its differentiation, its physiological activities and in its method of reproduction. Generally, the thallophytes comprise most of the soil flora considered important in soil fertility.

Salient Features of Thallophyta

(1) The plant body shows no differentiation of root, stem, and leaves and is known as a thallus or thalloid vegetative body. 

(2) Absence of vascular tissue in the plant body.

(3) Asexual reproduction by spore formation is quite common.

(4) The sexual reproductive organs are simple and unicellular. 

(5) No embryo formation after gametic fusion.

(6) Most plants are aquatic; the landforms are usually confined to moist places.

            The division thallophyta includes Algae (Phycophyta) and Fungi (Mycophyta). These were variously designated as division, subdivision or classes depending upon the system of classification. Some botanists also subdivide the thallophytes in four groups, Algae, Fungi, Bacteria and Lichens.
