B. It produces food from sunlight. 20. Which cell structures are similar in the way
C. Its jelly-like fluid surrounds the nucleus and they protect, support, and hold the other
most of the cell’s internal parts. organelles together?
D. It contains the cell’s nuclear material. A. Cell Wall, cytoplasm, and lysosomes
B. Cell membrane, cytoplasm, and ribosomes
C. Cell wall, cell membrane, and cytoplasm
D. Cell membrane, chloroplasts, and nucleus
ANSWERS
1. plant cell is rectangular, has cell wall, chloroplasts, and one large vacuole but animal cell is circular, doesn’t have a cell
wall or chloroplasts and has many small vacuoles.
2. adjust the focus using the knobs, make sure the objective is in place, reposition the slide on the stage, turn on the
microscope, plug in the microscope, adjust the amount of light coming through, select the objective with the lowest
magnification (shortest one), etc.
