Correct Answer
C. UnicellularExplanation
The term "unicellular" refers to an organism that is composed of a single cell. This means that all of the functions and structures necessary for life are contained within that one cell. Examples of unicellular organisms include bacteria and protozoa. In contrast, multicellular organisms are made up of multiple cells that work together to form tissues, organs, and systems. Therefore, the correct answer in this case is "unicellular" because it accurately describes an organism consisting of a single cell.Rate this question:

The ribosome is a small organelle in cells where proteins are made from amino acids. It is responsible for protein synthesis, which is a vital process for the functioning of cells. Ribosomes can be found in both prokaryotic and eukaryotic cells, and they are composed of RNA and proteins. During protein synthesis, the ribosome reads the genetic information from mRNA and assembles the amino acids in the correct order to form a protein. Therefore, the ribosome plays a crucial role in the production of proteins, which are essential for various cellular functions.Rate this question:

B. EcosystemExplanation
An ecosystem refers to a community of organisms that live in a specific area and interact with each other and their nonliving environment. It includes both living organisms, such as plants, animals, and microorganisms, as well as the physical factors of the environment, such as temperature, sunlight, soil, and water. Ecosystems can vary in size and can be found in various locations, such as forests, deserts, and oceans. They are characterized by the flow of energy and the cycling of nutrients between organisms and their environment.Rate this question:

- C.
Tissue
- D.
Cell Membrane
- E.
Golgi Complex
Correct Answer
C. TissueExplanation
Tissue is a group of similar cells that work together to perform a specific job in the body. It is the correct answer because the other options, such as organism, organ, cell membrane, and Golgi complex, do not accurately describe a group of cells working together. Organism refers to a complete living being, organ refers to a structure made up of different tissues, cell membrane is a protective layer around the cell, and Golgi complex is an organelle involved in packaging and transporting proteins.Rate this question:

Chloroplasst
Correct Answer
E. ChloroplasstExplanation
Chloroplasts are the organelles found in plant and algae cells where photosynthesis occurs. During photosynthesis, chloroplasts capture sunlight and convert it into chemical energy, which is then used to produce glucose and oxygen. This process is essential for the plant's survival as it provides energy for growth and development. Chloroplasts contain chlorophyll, a pigment that gives plants their green color and is responsible for absorbing light energy. Without chloroplasts, plants would not be able to carry out photosynthesis and produce their own food. Therefore, the correct answer is Chloroplast.Rate this question:
