Which one pair of examples will correctly represent the grouping Spermatophyta according to one of the schemes of classifying plants:
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
S.No. | List - I | List - II | List - III |
---|---|---|---|
I | Algae | Phaeophyceae | Sargassum |
II | Bryophyta | Hepaticopsida | Marchantia |
III | Pteridophyta | Pteropsida | Equisetum |
IV | Gymnosperms | Gnetopsida | Pinus |
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
A full wave rectifier circuit with diodes (\(D_1\)) and (\(D_2\)) is shown in the figure. If input supply voltage \(V_{in} = 220 \sin(100 \pi t)\) volt, then at \(t = 15\) msec:
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
The Plant Kingdom comprises all the plants that have some shared characteristics. These are bacteria (prokaryotes), photosynthetic plants, fungi, and several non-photosynthetic plants.
