In this article we will discuss about the thallus organisation found in algae. The plant body in algae is always a thallus. It is not differentiated in root, stem and leaves. Algae range in size from minute unicellular plants (less than 1 ยต in diameter in some planktons) to very large highly differentiated multicellular forms e.g., some sea-weeds. Their forms [...]
In this article we will discuss about the thallus and cell structure of oedogonium with the help of suitable diagrams. Thallus Structure of Oedogonium: The thallus is made of green, multicellular, un-branched filaments. The filament is made of three types of cells (Fig. 1): (i) The lower-most basal cell or holdfast. (ii) The intercalary cells. (iii) The upper-most apical cell. [...]
In this article we will discuss about the thallus and cell structure of hydrodictyon with the help of suitable diagrams. Thallus Structure of Hydrodictyon: A mature coenobium consists of a hollow cylindrical network which is closed at both the ends (Fig. 1). It is flat and saucer shaped and its maximum size is generally 20-30 cm. Rarely it may reach [...]
