Question

animal cells are surrounded by a(n) __________ whereas plant cells are also surrounded by a(n) __________. nuclear membrane, endomembrane; plasma membrane; cell wall; plasma membrane; endomembrane; endomembrane; cell wall. part b which organelles comprise the endomembrane system of a cell? mitochondrion, endoplasmic reticulum, golgi apparatus; mitochondrion, chloroplast, plasma membrane; plasma membrane, nuclear membrane, endomembrane; endoplasmic reticulum, golgi apparatus, lysosome

Explanation:

1. For the first question, animal cells are surrounded by a plasma membrane which controls the movement of substances in and out of the cell. Plant cells have a plasma - membrane as well, but they are also surrounded by a rigid cell wall which provides structural support and protection.
2. For the second question, the endomembrane system of a cell includes the endoplasmic reticulum, Golgi apparatus, and lysosome. The endoplasmic reticulum is involved in protein and lipid synthesis, the Golgi apparatus modifies, sorts, and packages proteins and lipids, and lysosomes contain digestive enzymes for breaking down waste materials.

Answer:

Part A: B. plasma membrane; cell wall
Part B: D. endoplasmic reticulum, Golgi apparatus, lysosome
