Questions: Multiple Choice Question This image shows animal cells growing in a in a tissue culture dish. bilayer plaque monolayer bird embryo

The answer is the third one (or C): monolayer.

Explanation for each option:

• Bilayer: This term typically refers to a double layer of molecules, such as the phospholipid bilayer in cell membranes. It is not commonly used to describe the arrangement of cells in a tissue culture dish.
• Plaque: In the context of cell cultures, a plaque usually refers to a clear area on a layer of cells where virus-infected cells have been destroyed. It does not describe the general growth pattern of animal cells in a culture dish.
• Monolayer: This is the correct term. Animal cells in a tissue culture dish often grow in a single layer, known as a monolayer, where each cell is in contact with the surface of the dish.
• Bird embryo: This option is unrelated to the context of animal cells growing in a tissue culture dish. Bird embryos are used in different types of biological research but not typically described in this context.

Summary: The image shows animal cells growing in a monolayer in a tissue culture dish.
