Tamia was observing a specimen using a microscope. She observed multiple cells on the slide that seemed to clump together. She also noticed a nucleus in each cell, and the cells were round in shape. The cells all had the same appearance without any structures that would be used for movement. Tamia concluded she was looking at some kind of animal cells. What evidence from her observations best supports this claim? Choose all that apply.(3 points)

To best support Tamia's claim that she was looking at animal cells, the following observations provide strong evidence:

  1. The cells contained structures found in an animal cell like a nucleus and cell membrane. - This indicates that the cells have characteristics typical of animal cells.

  2. The cells did not contain the structures found in plant cells, like a cell wall or chloroplasts. - The absence of these structures suggests that the cells are not plant cells, reinforcing the idea that they are likely animal cells.

  3. The cells did not contain structures for movement like those found in unicellular organisms. - This observation supports the notion that these cells are not from unicellular organisms, which often have structures for movement, further pointing towards them being animal cells.

Therefore, the correct responses to support her conclusion are:

  • The cells contained structures found in an animal cell like a nucleus and cell membrane.
  • The cells did not contain the structures found in plant cells, like a cell wall or chloroplasts.
  • The cells did not contain structures for movement like those found in unicellular organisms.
