Question

1. which organelle in eukaryote cells functions as the packaging and shipping facility for the cell?

nucleus
golgi apparatus
vacuole
rough endoplasmic reticulum

1. using a microscope in the science lab, jill observed two unknown cells: cell 1 and cell 2. cell 1 she identified as a plant cell and cell 2 as an animal cell. her teacher told her she identified the cells correctly. what did jill most likely observe to correctly identify the cells?

a. cell 2 had a cell membrane and cell 1 did not.
b. cell 1 had a cell wall and cell 2 did not.
c. cell 2 had a chloroplast and cell 1 did not.
d. cell 1 had a nucleus and cell 2 did not.

Explanation:

• Question 25: The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles, acting as the cell's packaging and shipping facility. The nucleus stores genetic information, the vacuole mainly stores substances (especially in plant cells), and the rough endoplasmic reticulum is involved in protein synthesis.
• Question 15: Plant cells have a cell wall (a rigid structure outside the cell membrane), while animal cells do not. Both plant and animal cells have a cell membrane (so option a is wrong). Chloroplasts are in plant cells (for photosynthesis), not animal cells (so option c is wrong). Both plant and animal cells have a nucleus (so option d is wrong).

Answer:

• 25. golgi apparatus
• 15. b. Cell 1 had a cell wall and Cell 2 did not.
