Question

during science class, a group of students went on a field trip to a nearby pond where they collected samples of pond water and pond plants. the students used a microscope to study cells in their samples. they also took samples of their own cheek cells and studied them using the microscope. the results are shown in the following table. 5 using the table provided, determine which of the following pairs of organelles or structures can be found in both plant and animal cells. ○ a. cell wall and chloroplast ○ b. cell wall and nucleus ○ c. vacuole and chloroplast ○ d. cell membrane and nucleus

Explanation:

• Cell Wall: Present in plant cells (pond plant cells and pond organism #1) but absent in animal cells (cheek cells and pond organism #2). So options with cell wall (A, B) are incorrect.
• Chloroplast: Present in plant cells (pond plant cells and pond organism #1) but absent in animal cells (cheek cells and pond organism #2). So options with chloroplast (A, C) are incorrect.
• Cell Membrane and Nucleus: Looking at the table, cheek cells (animal - like) have nucleus (\(X\)) and cell membrane (\(X\)), pond plant cells (plant - like) have nucleus (\(X\)) and cell membrane (\(X\)), pond organism #1 (plant - like) has nucleus (\(X\)) and cell membrane (\(X\)), pond organism #2 (animal - like) has nucleus (\(X\)) and cell membrane (\(X\)).

Answer:

D. cell membrane and nucleus
