1. Why is the cell called the structural and functional unit of life? Ans:- Cells are the basic unit of life. A group of cells form a Tissue, a group of tissues form an organ, a group of organs forms an organ system and a group of organ systems form an organism[ a living creature]. Thus cells form the structure of a living being. A cell is the simplest unit in an organism where all the life processes take place, such as respiration, digestion, excretion, reproduction, etc. Thus making it the functional unit of life. 2. Ans:- Option C- Virus.

"Among the options provided, viruses have the potential to be crystallized due to their uniform size and shape, rigid structure, and lack of cellular complexity. When arranged in an orderly manner, thousands of virus particles can form a crystal lattice. Your dedication and passion for teaching make learning enjoyable and rewarding. Your patience, innovative methods, and mentorship inspire us to excel. Thank you for making a difference in our learning journey at Byju's!"

Option c In laboratory settings, viruses can be crystallized under specific conditions, typically by concentrating them and inducing crystallization using methods like dialysis or vapor diffusion. This process involves carefully controlling factors such as temperature, pH, and the concentration of viral particles and precipitants. When the conditions are just right, the individual viral particles align themselves in a repeating pattern, forming a crystal lattice. This crystallization process allows scientists to study the structure of viruses using techniques like X-ray crystallography, which can provide valuable insights into their molecular structure and function. However, it's important to note that this crystallization is an artificial process done in controlled environments and does not reflect how viruses naturally exist in living organisms.

Option c virus thank you for the session

[@Anugrah8910]

chatgpt lol, only chatgpt begins with "certainly"

[@Sonakshi2004]

Answer: Virus because virus remains as a non-living entity outside the host. They can multiplied and start living once they invade the host outside the host they don't multiply and exit in the form of crystal . Thank you mam for this amazing session ❤️.

[@samritha-nl5uh]

Answer is virus as it is in boundary between living and non living it can be easily crystalized.Thank you mam

[@hansujasahoo8481]

Answer of homework question:- Virus can be made into crystals because they are uniform in size and shape. The virus crystal consists of thousand of viruses. I love ❤byjus

[@Rupal_exo_planet_9]

The answer for the homework question is c) A Virus.

[@ChesterMester]

Homework question - Ayush(Hope i make it to the homework warriors!) Option c (virus) Reasons - Lack metabolism and hence can be subject to crystallization and stored in jars for years . They also exhibit a lack of respiration . Features- - Do not exhibit a proper cellular structure ; acellular as per elaborated by Aishwarya mam -Exception to cell theory -Not capable of independent existence without a host cell
