| Coralloid roots of Cycas |
Coralloid roots of cycas
Coralloid roots are a unique feature of the Cycas plant. These roots are specialized structures that form a symbiotic relationship with cyanobacteria, which are photosynthetic microorganisms that live inside the roots. The roots are called "coralloid" because they resemble coral in appearance and texture.
The cyanobacteria in the coralloid roots of Cycas plants are known to fix atmospheric nitrogen, converting it into a form that can be used by the plant to support its growth and development. This is particularly important for Cycas plants, which often grow in nutrient-poor soils.
In addition to their symbiotic relationship with cyanobacteria, coralloid roots also play a role in anchoring the plant and absorbing water and nutrients from the soil. These specialized roots are typically found near the base of the stem, and they can grow up to several meters in length depending on the species of Cycas.
Reproduction of cycas

| egg Cycas |
Cycas is a dioecious plants, meaning that there are separate male and female plants. The reproduction of Cycas involves the production of cones that bear either male or female reproductive structures.
Male cones of Cycas are generally smaller and more numerous than female cones. They produce and release pollen grains, which are carried by the wind or small insects to the female cones. The pollen grains then fertilize the female cone, resulting in the development of seeds.
Female cones of Cycas are larger and take longer to mature than male cones. They produce ovules that, when fertilized by pollen, develop into seeds. After fertilization, the female cones take several months to mature and ripen, at which point they open to release the seeds.
Cycas also have a unique reproductive structure known as coralloid roots, which are specialized roots that contain cyanobacteria. These roots have a symbiotic relationship with the plant, fixing atmospheric nitrogen and converting it to a form that can be used by the plant. Coralloid roots are also thought to play a role in the reproduction of Cycas, as they may be involved in the production of certain hormones or signaling molecules that promote the growth and development of the male and female cones.
Overall, the reproduction of Cycas is a complex process that involves the development and maturation of male and female cones, the release of pollen and fertilization of ovules, and the eventual production of seeds. This unique reproductive strategy has allowed Cycas to survive for over 200 million years, making it one of the oldest lineages of plants on Earth.
Male cone of cycas
The male cone of Cycas is a reproductive structure that produces and releases pollen, which is necessary for the fertilization of the female cones. Cycas plants are dioecious, meaning that male and female reproductive structures are found on separate plants. The male cones are typically smaller and more numerous than the female cones.
 |
| The male cone of Cycas |
The male cones of Cycas are generally cylindrical in shape, and they are composed of numerous scales that are tightly packed together. Each scale has two chambers that contain pollen sacs, which produce and release pollen grains.
The pollen of Cycas is unique in that it does not have wings or any other specialized structures for dispersal. Instead, it relies on physical contact with the female cones for fertilization to occur. This is typically facilitated by insects or other animals that visit the plant and transfer pollen between the male and female cones.
Once the male cones have released their pollen, they typically wither and die, and the plant will produce new cones in subsequent growing seasons. Overall, the male cones of Cycas play a critical role in the reproductive cycle of the plant, allowing it to produce offspring and ensure the survival of the species.
Describe the structure of the male cone of cycas
The male cone of Cycas is a large, elongated structure that grows at the top of the trunk or on the branches of male Cycas plants. It is typically cylindrical or cone-shaped and can range in size from several inches to several feet in length, depending on the species.
The male cone of Cycas is composed of many thin, overlapping scales that are arranged in a spiral pattern around the central axis of the cone. Each scale bears several pollen sacs, which contain the male reproductive cells called pollen grains.
As the male cone of Cycas matures, the pollen sacs within the scales begin to open, releasing the pollen grains into the environment. The pollen grains are typically dispersed by wind or small insects, and can travel long distances before landing on the female cones of Cycas and fertilizing the ovules.
Overall, the structure of the male cone of Cycas is specialized for the production and dispersal of pollen, which is critical for the plant's reproductive success.
Female cones of Cycas

| Female cones of Cycas |
Female cones of Cycas are large, woody structures that develop at the top of the trunk or on the branches of female Cycas plants. They are typically oblong or cylindrical in shape, and can range in size from several inches to several feet in length, depending on the species.
Each female cone of Cycas contains numerous ovules, which are the female reproductive structures that, when fertilized by pollen, develop into seeds. The ovules are located on the upper surface of the cone scales, which are arranged in a spiral pattern around the central axis of the cone.
As the female cone of Cycas matures, it becomes covered in a waxy coating that protects it from water and other environmental stresses. The scales of the cone begin to open gradually, revealing the ovules within. Pollen from the male cones is carried by wind or small insects to the female cones, where it fertilizes the ovules and initiates the development of seeds.
Once the seeds are mature, the female cones of Cycas split open, releasing the seeds. The seeds are typically large and have a hard, outer layer, which helps to protect them from damage during dispersal.
Overall, the female cones of Cycas are a key component of the plant's reproductive cycle, and play an important role in the development and dispersal of its seeds.
