Download Now Cycas are perennial evergreen trees. They appear like a palm tree. They are characterised by the presence of naked seeds, i.e. ovules are not enclosed within the ovary. The main body part is the diploid sporophyte. Cycas are dioecious, i.e. the male and female plants are separate. Table of Content Classification Morphology of Cycas

Figure 2.6.2.1.1 2.6.2.1. 1: Ginkgo leaves have a distinctive shape that has remained relatively unchanged from their fossil record: a fan-shaped leaf that is often deeply dissected in the center (the specific epithet biloba means two lobes). The fossil leaf on the right is around 60 million years old. First image: Ginkgo biloba leaves, photo.

Anatomy of Cycas Leaflet Ø Cycas leaflet is with distinct midrib and lateral wings. Mid-rib is swollen and the wings are flattened. Margins of the leaves are revolute (curved downward) in Cycas revoluta. Ø Anatomically, the leaf is differentiated into: § Upper Epidermis § Hypodermis § Mesophyll § Vascular Tissue § Lower Epidermis

Ø The T.S. of the stem is irregular in outline due to the presence of persistent leaf bases and leaf scars. Ø Cortex very large and composed of loosely packed parenchymatous cells. Ø Vascular tissue consists of many vascular bundles arranged as a ring. Ø Each vascular bundle is open and endarch. Ø The Pith very large and parenchymatous.
