What are true of cells?
Cells are the fundamental units of life. Whether they be unicellular or multicellular life forms, all living organisms are composed of and depend on cells to function normally. … Cells do everything from providing structure and stability to providing energy and a means of reproduction for an organism.
Which of the following are not found in all cells?
Which of the following structures is NOT found in all types of cells? Nucleus. Prokaryotic cells don’t have them. What does the Golgi apparatus do?
Which of the following is not a cell theory?
The correct answer is All cells are identical. Cells are the smallest units of life and hence are often referred to as the building blocks of life. The study of cells is called cell biology, cellular biology, or cytology.
What is not composed of cells?
Viruses. Viruses are acellular microorganisms, which means they are not composed of cells. Essentially, a virus consists of proteins and genetic material—either DNA or RNA, but never both—that are inert outside of a host organism.
What organelles are not found in all cells?
Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis. The cytoplasm is all the contents of the cell inside the cell membrane, not including the nucleus.

Which of the following is not part of the Endomembrane system?
Mitochondria, chloroplast and peroxisomes are not the part of endomembrane system because their function are not coordinated with the same.
Which of the following is not true regarding virus?
They can be cultured in artificial media lacking living cells. They do not have the problem synthesizing machinery of their own. They may contain RNA as the genetic material.
Which among the following is not a microorganism?
Microorganisms can be bacteria, fungi, archaea or protists. The term microorganisms does not include viruses and prions, which are generally classified as non-living. There is currently a great deal of discussion about the organisation and classification of life, particularly in the study of microorganisms.
Which is not a use of microorganism?
Explanation: generally microorganisms can be used for all of the above reasons. But they are not used in increasing the soil fertility, farmers prefer organic things like manure and earthworms .
Which of the following statement is not true for retroviruses?
DNA is not present at any stage in the life cycle of retroviruses.
Which type’s of microorganisms have cells that do not contain organelles?
Which type(s) of microorganisms have cells that do NOT contain organelles? Bacteria and Archaea are prokaryotic and lack organelles.
What is true about the viral envelope?
The envelopes are typically derived from portions of the host cell membranes (phospholipids and proteins), but include some viral glycoproteins. They may help viruses avoid the host immune system. Glycoproteins on the surface of the envelope serve to identify and bind to receptor sites on the host’s membrane.
Which of the following is not true about TMV?
2. Which of the following is not true for TMV Virus? Explanation: TMV or Tobacco Mosaic Virus causes viral infection to the tobbacco plant. It is a rod-shaped helical RNA virus which consists of a single strand of RNA placed centrally enveloped by a protein coat.
Which of the following is true about retrovirus?
Retroviruses are so named because they contain the enzyme reverse transcriptase or RNA-dependent DNA polymerase (RdRP). The genetic material of these viruses is RNA. From their genetic RNA they produce DNA using RdRP; e.g., Rous sarcoma virus.
Which of the following statement is not true in case of DNA polymerase reverse transcriptase *?
Answer: Explanation: Reverse transcriptase is involved in the replication of several kinds of viruses. Reverse transcriptase is unique in that it uses as a template not DNA but RNA.
Which of the following is not true for a bacteriophage?
1. Which of the following is not true for a bacteriophage? Explanation: Bacteriophages are viruses that specifically infect bacteria but these are very simple structures consisting merely of a DNA/RNA molecule surrounded by a protective coat. 2.
Which of the following is not a type of virus *?
2. Which of the following is not a type of virus? Explanation: Types of viruses are System or Boot Sector Virus, Direct Action Virus, Resident Virus, Multipartite Virus, Polymorphic Virus, Overwrite Virus, Space-filler Virus, File infectors, Macro Virus, Rootkit virus. Trojan does not come under types of virus.
Which of the following statement is true about Virion?
3. Which of the following statements are true about a virion? Sol: (d) An infectious and fully formed viral particle.
Which of the following is true for bacteriophage?
Detailed Solution. The correct answer is These are viruses which are not living organism and are a major contributor to the ecosystem. “Bacteriophages, or “phages” for short, are viruses that specifically infect bacteria.
Which of the following is true for the bacteriophage MV L2?
Which of the following is true for the bacteriophage MV-L2? Explanation: Bacteriophage MV-L2 has a filamentous form. This type is found in some plant viruses.
