During epigeal germination, cotyledons come out of the soil. The green cotyledons function as leaves of the seedling. They manufacture food and sustain the young seedling till the plumule gives rise to new leaves.

3.3 PTERIDOPHYTES The Pteridophytes include horsetails and ferns. Pteridophytes are used for medicinal purposes and as soil-binders. They are also frequently grown as ornamentals. Evolutionarily, they are the first terrestrial plants 10 possess vascular tissues - xylem and phloem. You shall study more about these tissues in Chapter 6 . The pteridophytes are found in cool, damp. shady places though some may flourish well in sandy-soil conditions. You may recall that in bryophytes the dominant phase in the life cycle is the gametophytic plant body. However, in pteridophytes, the main plant body is a sporophyte which is differentiated into true root. stem and leaves (Figure 3.3). These organs possess well-differentiated vascular tissues. The leaves in pteridophyta are small (microphylls) a5 in Selaginella or large (macrophylls) as in ferns. The sporophytes bear sporophylls. structures called some cases sporophylls may form distinet compad sporangla prodled strobili or cones (Selaginella, Equisetum).

xylem and phloem parenchyma (vii) Photosynthesis in the form of chlorenchyma. (viii) Provid. ing buoyancy and storage of metabolic gases in the form of aerenchyma. (ix) Secretion. Collenchyma (Gk kolla- glue, enchyma- tissue) Collenchyma is a simple permanent tissue of refractile nonlignified living cells which possess pectocellulose thickenings in specific areas of their walls. The cells appear conspionous under the microscope due to their higher refractive index. The cells are often elongated They are circular, oval or angular in transverse section. Internally each cell possesses a larga central vacuole and a peripheral cytoplasm. Chloroplasts are often present. Wall possesses uneven longitudinal thickenings in specific areas. Depending upon the thickening, collenchyma is of three types : (i) Angular Collenchyma. The thickenings are present at the angles (angular thickenings), e.g., stem of Tagetes, stem of Tomato (Fig. 6.5 B). (ii) Lamellate Collenchyma. The thickenings occur on the tangential walls (plate thickenings). e.8., stem of Sunflower (Fig. ). (iii) Lacunate Collenchyma. The thickenings are found on the walls bordering intercellular spaces (lacunate thickenings), e.g., Cucurbita stem
