Polysaccharides play crucial roles in living things due to their diverse functions and properties. As complex carbohydrates made up of multiple sugar units, they serve as important sources of energy and structural components in organisms.
1. **Energy Storage:** One primary role of polysaccharides is to store energy for short-term and long-term use. Plants store excess glucose in the form of starch, while animals store it as glycogen in the liver and muscles.
2. **Structural Support:** Polysaccharides provide structural support in cell walls of plants, algae, and some bacteria. For example, cellulose forms the rigid cell walls of plant cells, giving them shape and support.
3. **Protection and Lubrication:** Some polysaccharides, like chitin found in the exoskeletons of insects and crustaceans, provide protection and structural support. Hyaluronic acid, a polysaccharide in connective tissues, acts as a lubricant and shock absorber.
4. **Cell Recognition:** Polysaccharides are also involved in cell recognition and signaling processes. They form part of cell surface markers and play essential roles in immune responses and cell communication.
Overall, polysaccharides are essential biomolecules that fulfill diverse functions, contributing to the proper functioning and structure of living organisms.

Answer: A) Bacteria.
Bacteria are the most primitive life forms on earth. Organelles are the subcellular compartments of cell enclosed by lipid layer and impart the specific function to it.
Bacteria are prokaryotes, thus lack membrane-bound organelles. Whereas Fungi, Plants, and Protist being eukaryotes, consist of membrane-bound organelles.
Answer:
The correct term would be the scientific method.
Explanation:
The Scientific Method is a proper way that helps researchers or scientists answer a curiosity question or solving a problem. It is used to prove or support a particular hypothesis. It has usually six parts to it -
Purpose/Question
Research
Hypothesis
Experiment
