Write down the characteristics of Thallophyta and Bryophytes.
➡ They are usually found in moist or wet places.
➡ This is due to the absence of “true roots” and vascular tissue that is needed to transport water and minerals. Hence they are found in moist or wet places.
➡ They are autotrophic in nature.
➡ Most members in this group manufacture their own food. But a few members like fungi are dependent on other sources of food.
➡ Reserve food is generally starch.
➡ They have a cell wall composed of cellulose around their cells.
____________________________________
➡ All of these are land plants (terrestrial) with some aquatic forms.
➡ They are very small. The sporophyte and gametophyte have very different morphologies (heteromorphic generations) and the sporophyte is usually partly dependent on the gametophyte.
➡ Photosynthetic, non-vascular plants
➡ Cuticle and stomata are absent.
➡ The gametophyte generation is dominant, conspicuous and independent.
➡ Spores are produced as a direct result of meiosis.
