Which one pair of examples will correctly represent the grouping Spermatophyta according to one of the schemes of classifying plants:
Which one pair of examples will correctly represent the grouping Spermatophyta according to one of the schemes of classifying plants:
- Acacia, Sugarcane
- Pinus, Cycas
- Rhizopus, Triticum
- Ginkgo, Pisum
The Correct Option is D
Solution and Explanation
Spermatophyta, a category encompassing seed-bearing plants, comprises two major groups gymnosperms and angiosperms. Acacia and sugarcane fall within the category of angiosperms, while Pinus and Cycas are classified as gymnosperms. Notably, Rhizopus belongs to the fungal kingdom, whereas Triticum is categorized as an angiosperm. Ginkgo is a gymnosperm, which differentiates it from Pisum (pea), an angiospermic plant. In summary, Rhizopus is a fungus, Triticum is an angiosperm, and Ginkgo is a gymnospermic plant.
So, the correct option is (D): Ginkgo, Pisum

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.
