Q. Who said that plants were made of cells?
Theodor Schwann
Q. Who was the first person to conclude that all plants have cells?
The classical cell theory was proposed by Theodor Schwann in 1839. There are three parts to this theory. The first part states that all organisms are made of cells.

Q. WHO concluded that all plants?
Matthias Schleiden
Q. How was Schwann’s conclusion similar to Schleiden?
In 1839, Theodor Schwann, a German biologist, reached the same conclusion as Schleiden about animal tissue being composed of cells, ending speculations that plants and animals were different in structure. Schwann described cellular structures in animal cartilage. In other words, the cell is the basic unit of life.
Q. Where did Schleiden incorrectly think cells came from?
Schwann believed that cells did not have to come from preexisting cells whereas Schleiden believed all cells came from preexisting cells.
Q. What was Schleiden convinced of?
Although the mechanism by which cells multiplied was unclear, Schleiden was quite opposed to the doctrine of spontaneous generation. He was convinced that even the simplest plants, such as algae, lichens, and fungi, arose from parents of the same kind, not from spontaneous generation out of nonliving substances.
Q. What do we call the tiny parts inside of cells?
organelles
Q. How can you tell if a substance is a bacteria?
Bacteria are identified routinely by morphological and biochemical tests, supplemented as needed by specialized tests such as serotyping and antibiotic inhibition patterns. Newer molecular techniques permit species to be identified by their genetic sequences, sometimes directly from the clinical specimen.
Q. What are spore forming bacteria capable of?
Spore-forming bacteria are heat-resistant microorganisms capable of surviving and germinating in milk after pasteurization.
Q. Is Spore a virus?
Despite the high number of viral gene copies associated with spores, no mature virus-like particles were observed via TEM (Fig. 3g). Spore formation represses viral propagation in Chaetoceros socialis.
Q. What is the difference between a virion and a virus?
Virus is a non-cellular, obligate parasite that is self-replicative inside a specific host cell. Virion is another form of a virus. The main difference between virus and virion is that virus is the nucleoprotein particle whereas virion is the active, infectious form of the virus.
Q. What is a spore in food safety?
Spores are bacteria and Fungi in a dormant state, where they are generally not actively metabolising. Some pathogens can form spores when in adverse condition i.e. severe heat or severe acidity but then become active when conditions are more favourable e.g. a product in the danger zone, between cooking and cooling.
