Question

Dr. Roberts examined the cells of four different organisms for the presence of various cellular structures. His observations are recorded in the table below. (An "X" indicates that the structure is present in the cell.)

cell
membrane cell wall chloroplasts mitochondria nucleus ribosomes vacuoles
1 X X X X X X X
2 X X X X X
3 X X X
4 X X X X
Using the information in the table, which of the cells most likely came from an animal?

Answer 1

Cell 2 most likely came from an animal because it lacks a cell wall and chloroplasts, which are unique to plant cells.

Step-by-step explanation:

In the given table, the cell that most likely came from an animal is cell 2. This is because cell 2 does not have a cell wall or chloroplasts, which are structures found in plant cells but not in animal cells.

Answer 2

2 because animals do not have chloroplast or a cell wall
