Which of the following gymnosperms is a bushy trailing shrub ?
Show Hint
Ephedra is a bushy trailing, climbing, or creeping herbaceous gymnosperm. It is a genus of gymnosperm shrubs. It is a medication used to treat colds, hay fever, and asthma.
Therefore, the correct option is (A) Ephedra.
- Ephedra
- Cycas
- Pinus
- Araucaria
The Correct Option is A
Solution and Explanation
The correct option is: (A) Ephedra
Explanation: Almost all gymnosperms are perennial woody trees, and only a few are bushy, trailing shrubs. Examples include Ephedra and Gnetum.
Ephedra: Ephedra is a shrub of the genus Gymnosperm. It has been used as traditional Chinese medicine for many years in the treatment of asthma and bronchitis.
Cycas: Cycas is a genus of gymnosperms; it is a type of seed plant called a Cycad. Cycads are not bushy, trailing gymnosperms; instead, they have a trunk or stem from which their leaves emerge (consisting of large compound leaves).
Pinus: Pinus belongs to the coniferous group of gymnosperms. They are well-known as pine trees, characterized by tall, straight trunks and needle-like leaves arranged in clusters. Pines are typically recognized for their cone-bearing structures.
Araucaria: Araucaria is a genus of coniferous trees belonging to the family Araucariaceae. These trees typically have a straight, upright trunk with branches radiating outward in a more or less regular pattern.
Therefore, the correct option is A) Ephedra.

Plant Kingdom
The Plant Kingdom comprises all the plants that have some shared characteristics. These are bacteria (prokaryotes), photosynthetic plants, fungi, and several non-photosynthetic plants.

Several features of Kingdom Plantae are as follows:
- They are stationary. They are static and usually remain in one place only.
- They have branches that expanded and green leaves due to the presence of chlorophyll.
- They are an autotrophic mode of nutrition that simply means they prepare their food with the help of water, sunlight and carbon dioxide. It is further known as self-nutrition.
- They indulge in photosynthesis during the day and therefore more carbon dioxide is needed during the day and at night it is released.
- They secure their food in the form of starch-like algae.
- They have an inelastic wall around their cell known as a cell wall comprised of cellulose.
- There is an absence of the nervous system and excretory system.
- Reproduction is entirely dependent on air, insects and water. Asexual and vegetative method of reproduction is noticed or detected.
- The non-photosynthetic plants acquire their food through parasitism, i.e through their host like Indian pipe.
