Prokaryotic cells do not have a nucleus. Eukaryotic cells do have a nucleus.
Autotroph means it can make its own food. Heterotroph means it must obtain nutrients from another organism.
Asexual reproduction involves only one parent, and the offspring are genetically identical to that parent. Sexual reproduction involves two parents, and the offspring share a combination of each parent’s characteristics and genetics.
- If an organism has eukaryotic cells, is unicellular, and is an autotroph, to which kingdom does it have to belong?
- What does the word “prokaryotic” mean? Bacteria are among the best-known prokaryotic organisms
- What does the word “autotroph” mean?
- If an organism has prokaryotic cells and reproduces asexually, to which two kingdoms might it belong? OR
- To which kingdom would an organism belong if it is multicellular, a heterotroph and reproduces sexually? OR
- Which type of reproduction results in offspring that are genetically. identical to the single parent?
- Which kingdom contains eukaryotic autotrophs that reproduce sexually?
The Correct Answer and Explanation is :
- If an organism has eukaryotic cells, is unicellular, and is an autotroph, to which kingdom does it have to belong?
- Answer: Protista. Organisms in the kingdom Protista can be unicellular, eukaryotic, and autotrophic. This kingdom is diverse, containing both autotrophic (make their own food, like algae) and heterotrophic organisms (which rely on others for food).
- What does the word “prokaryotic” mean?
- Answer: Prokaryotic means cells that do not have a nucleus. These cells have simpler structures and lack membrane-bound organelles, such as a nucleus. Bacteria are common examples of prokaryotic organisms. Prokaryotes are smaller than eukaryotic cells and have a simpler form of genetic material.
- What does the word “autotroph” mean?
- Answer: An autotroph is an organism that can make its own food. This is typically done through photosynthesis (in plants) or chemosynthesis (in some bacteria), where the organism converts sunlight or chemicals into energy. Autotrophs are essential in ecosystems because they form the base of the food chain.
- If an organism has prokaryotic cells and reproduces asexually, to which two kingdoms might it belong?
- Answer: Archaebacteria and Eubacteria. Both kingdoms contain prokaryotic organisms. Archaebacteria often live in extreme environments, while Eubacteria are more commonly found in regular environments. They reproduce asexually through binary fission.
- To which kingdom would an organism belong if it is multicellular, a heterotroph, and reproduces sexually?
- Answer: Animalia. Organisms in the kingdom Animalia are multicellular, heterotrophic (they consume other organisms for food), and typically reproduce sexually. Animals exhibit complex behaviors and life cycles, and their cells contain nuclei (eukaryotic cells).
- Which type of reproduction results in offspring that are genetically identical to the single parent?
- Answer: Asexual reproduction. This type of reproduction involves one parent, and the offspring are clones of that parent, genetically identical. Examples include binary fission in bacteria and budding in yeast.
- Which kingdom contains eukaryotic autotrophs that reproduce sexually?
- Answer: Plantae. Plants are eukaryotic, multicellular, autotrophic organisms that make their own food through photosynthesis. Most plants reproduce sexually, though some can reproduce asexually as well. The sexual reproduction process involves the combination of male and female gametes to produce seeds.
Explanation:
In biology, organisms are classified into six kingdoms: Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia. The key distinction between these kingdoms is their cell type (prokaryotic or eukaryotic), structure (unicellular or multicellular), and how they obtain food (autotroph or heterotroph). Prokaryotic cells, such as those in the kingdoms Archaebacteria and Eubacteria, lack a nucleus, while eukaryotic cells (in Protista, Fungi, Plantae, and Animalia) have a true nucleus. Autotrophs can produce their own food, while heterotrophs rely on consuming other organisms. Reproduction can be sexual or asexual, affecting the genetic diversity of offspring.
