cell theory- the basic unit from which living organisms are built up consisting of a mass cytoplasm surrounded by a plasma membrane. the body of an individual plant or animal contains many different types of cell, each being specialized and adapted for a particular function. the process by which cells become specialized is why is called differentiation.
What else can I help you with?
How would you be able to distinguish parts of the organisms using a microscope?
by looking at the species and see if it has a cell then you know it is a plant cell and if it has no then it is an animal cell
How might the scientists use the cell theory to determine if the object is an organism?
Scientists could use the cell theory to determine if an object is an organism by examining its structure under a microscope for evidence of cells. If the object is composed of cells with a defined nucleus and membrane-bound organelles, it would align with the principles of the cell theory and likely be considered an organism. Additionally, observing characteristics such as growth, reproduction, and response to stimuli would further support this classification.
What is organismal theory?
In plants, the organismal theory refers to the idea that during plant growth/evolution the original cell expanded into the whole organism. This is opposed to the cell theory that states that a cell multiplies into many cells with the original cell being equivalent to many. In this theory, the original cell is equivalent to the entire organism, with protoplasm just being subdivided and partitioned by cell walls (which are actually incomplete partitions because the protoplasms of adjacent cells are connected by plasmodesmata).
What piece of evidence would cause scientists to decide that cell theory would need to be revised?
If scientists were to discover a new type of organism that does not fit the characteristics of cells as defined by cell theory, such as lacking a cell membrane or having a fundamentally different structure, then they may consider revising the cell theory to account for this new finding.
What is the scientific theory behind cell theory?
Cell theory states that all living organisms are composed of one or more cells, cells are the basic unit of structure and function in an organism, and all cells come from pre-existing cells through cell division. This theory is supported by multiple lines of evidence from observations made using microscopes and other scientific tools.
Why is cell theory still accepted today?
cell theory is accepted today because it is a unit of living organism.
How did Meyen contribute to the cell theory?
he stated that the cell is a structural unit of an organism.
Distinguish between organelle and organism?
organism is constituted of organelles.organelles are like mitochondria,chloroplast,golgi.......etc well to be more precise an organelle is an intercellular compartment in the cell in which different functions related to cells are performed. while an organism is a living thing made up of single cell or many cells and each cell is composed of different organelles
How would you be able to distinguish parts of the organisms using a microscope?
by looking at the species and see if it has a cell then you know it is a plant cell and if it has no then it is an animal cell
What could be used to distinguish between an organism in the domain bacteria and one in the domain eukarya?
One way to distinguish between an organism in the domain Bacteria and one in the domain Eukarya is by looking at their cell structure. Bacteria have prokaryotic cells without a nucleus or membrane-bound organelles, while Eukarya have eukaryotic cells with a nucleus and membrane-bound organelles. Additionally, the presence of peptidoglycan in the cell wall is a characteristic feature of bacteria, which is absent in eukaryotic organisms.
Do plants have cell?
yes, plants have cell walls but animal cells do not.
What is the difference between a unicellular organism and a single cell organism?
Cell is the structural and functional unit of life while ,unicellular organism refers to an organism. Cell is present in both unicellular and multicellular organisms where as , unicellular organisms are composed of only one cell.
What features can be used to distinguish between an animal cell and a plant cell?
Plant cell has definite shape while animal cell has irregular shape.
How might the scientists use the cell theory to determine if the object is an organism?
Scientists could use the cell theory to determine if an object is an organism by examining its structure under a microscope for evidence of cells. If the object is composed of cells with a defined nucleus and membrane-bound organelles, it would align with the principles of the cell theory and likely be considered an organism. Additionally, observing characteristics such as growth, reproduction, and response to stimuli would further support this classification.
What is the activity of an organism dependent on according to modern cell theory?
Cells being formed from pure water

What is the difference between multicellular organism and a single celled organism?
Single means 1... multi means more.... lets see if we use common sense a single cell organism has one cell and a multicellular organism has more than one cell.
