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

The cilia are in 4 - 5 spirals. • The male gametes of Cycas are 180 - 210 μ in size and largest in the plant kingdom. • The pollen tube apex is ruptured and the male gametes are released into the archegonial chamber. • Presence of multiciliated male gametes is the fern character shown by Cycas male gametophyte.

Cycas Coralloid Root Diagram. Ø These algae in the algal zone are symbiotic. Ø They help in nitrogen fixation. Ø The endodermis is single-layered and it separate stele from the cortex. Ø Pericycle multilayered and prominent. (3). Vascular Tissue. Ø Vascular tissue is located in the central region of the root.

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.

Methodology. We investigated the leaflet anatomy of 48 Cycas species grown in a common garden to ascertain the variation of anatomical traits and compared this to available phylogenetic and geographic information to determine patterns in this variation. Pivotal results.

Leaflet of Cycas is characterized by conspicuous xerophytic features. An epidermis of thick-walled, highly cuticularized cells with sunken stomata, confined to the undersurface; 1-2 layered hypodermis of highly cutinized and lignified cells.

There are two types of leaves - foliage leaves and scaly leaves. The foliage leaves are pinnate (or more rarely bipinnate) and arranged spirally, with thick and hard keratinose. [clarification needed] They are not permanent and fall off leaving back leaf-bases. The leaflets are articulated, have midrib but lack secondary veins.

The Cycas is a unique genus of gymnosperms, belonging to the family Cycadaceae. It is the only living genus identified in this family. With over 100 different species, Cycas plants are primarily found in regions of eastern and southeastern Asia. A significant number of Cycas species are also native to countries such as China, Australia, and India.

External Features of Cycas: 1. Sporophytic plant body attains a height of 8 to 15 feet or more and appears like a small palm. 2. The plant body is differentiated into roots, stem and leaves (Fig. 1). 3. Roots are of two types: normal roots and coralloid roots. 4. Normal roots grow deep into the soil and are well- branched and positively geotropic.

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.

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
