The plants of which of the following plant kingdoms are known as algae?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. Thallophyta
Algae are primarily found in the plant kingdom Thallophyta, which includes simple, non-vascular plants. These organisms lack true stems, roots, and leaves, and they typically live in aquatic environments, both freshwater and marine. Algae perform photosynthesis and range from microscopic phytoplankton to large seaweeds like kelp. They play a crucial role in producing oxygen and forming the base of aquatic food chains. Due to their simple body structure, they are grouped under the thallophytes in plant classification.
Explanation of Other Options
-
Angiosperms: These are flowering plants with seeds enclosed in fruits. They are advanced plants, not algae.
-
Pteridophyta: This group includes vascular plants like ferns, which have true roots, stems, and leaves, not algae.
-
Bryophyta: These are non-vascular plants like mosses and liverworts, adapted to moist habitats, but are not algae.
