Which kingdom contains autotrophic, multicellular; eukaryotic organisms with cell walls made of cellulose? Plantae Bacteria Fungi Animalia Protista’
The Correct Answer and Explanation is:
Correct Answer: Plantae
Explanation:
The kingdom Plantae includes autotrophic, multicellular, eukaryotic organisms that have cell walls made of cellulose. These organisms are commonly known as plants. They play a vital role in the ecosystem by producing oxygen and serving as the base of most food chains.
Organisms in this kingdom have eukaryotic cells, meaning their cells have a true nucleus and membrane-bound organelles. Unlike animals, they have rigid cell walls made primarily of cellulose, a complex carbohydrate that provides structural support and helps the plant maintain its shape. This cellulose wall is a key feature that distinguishes them from other kingdoms.
Most plants are autotrophs, which means they can make their own food through the process of photosynthesis. They use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process takes place in specialized organelles called chloroplasts, which contain the green pigment chlorophyll.
Plantae includes a wide range of organisms such as mosses, ferns, conifers, and flowering plants. Although they vary in size, structure, and habitat, all share common traits like multicellularity and autotrophy. Their tissues are organized into roots, stems, and leaves, which allow them to efficiently absorb nutrients, transport water, and carry out photosynthesis.
In contrast:
- Bacteria are prokaryotic and lack a nucleus.
- Fungi are also eukaryotic and multicellular but are heterotrophic and have chitin in their cell walls.
- Animalia includes heterotrophic and multicellular eukaryotes but lacks cell walls.
- Protista is a diverse group that includes both autotrophs and heterotrophs, mostly unicellular, though some are multicellular, but they don’t fit cleanly into the other kingdoms.
Thus, the correct answer is Plantae.
