Cycas is a gymnosperm as it has naked seeds.
Explanation:
Gymnosperms are a group of seed-producing plants that includes conifers, cycads, and ginkgo. The term "gymnosperm" comes from the Greek words "gymnos" (naked) and "sperma" (seed). Gymnosperms are characterized by several features, including:
- Naked seeds: Unlike angiosperms, which have seeds enclosed in fruits, gymnosperms have seeds that are not enclosed in an ovary or fruit. Instead, the seeds are exposed on the surface of a scale or cone.
- Woody stems: Gymnosperms have woody stems that provide support and allow for the transport of water and nutrients.
- Leaves: Gymnosperms have leaves that are often needle-like or scale-like, and are adapted to withstand cold and dry conditions.
- Pollen cones: Gymnosperms produce male cones that release pollen, which is carried by the wind to female cones.
Cycas is a genus of gymnosperm that belongs to the family Cycadaceae. The plants in this genus are commonly known as cycads, and they are native to tropical and subtropical regions of the world. Cycas has several features that classify it as a gymnosperm, including:
- Naked seeds: Cycas produces seeds that are not enclosed in a fruit or ovary. Instead, the seeds are exposed on the surface of a cone-like structure.
- Woody stems: Cycas has a woody stem that provides support and allows for the transport of water and nutrients.
- Leaves: Cycas has large, compound leaves that are adapted to withstand hot and dry conditions.
- Pollen cones: Cycas produces male cones that release pollen, which is carried by the wind to female cones.
In conclusion, Cycas is a gymnosperm because it has naked seeds, which is one of the defining features of this group of plants.

Ans is c) naked seeds...
Gymnosperm are the seed bearing vascular plants such as cycas, pinus, ginkgo ,yews and conifers, in which the ovules or seeds are not enclosed in an ovary. The seeds of gymnospermic plants are developed either on the surface of scales or leaf like appendages of cones or at the end of short stalks...
