which of the groupings below includes organelles found only in the endomembrane system?
golgi apparatus, lysosomes, vacuoles, and the endoplasmic reticulum
golgi apparatus, lysosomes, mitochondria, and the endoplasmic reticulum
golgi apparatus, lysosomes, vacuoles, and cell wall
nucleus, lysosomes, vacuoles, and the endoplasmic reticulum
golgi apparatus, cytoskeleton, vacuoles, and the endoplasmic reticulum

Explanation:

First Question (Function of Vacuole in Plant Cells)

• store molecules: Vacuoles in plant cells store water, nutrients, waste products, and other molecules.
• divide the cell into compartments: Internal membranes (like ER) divide the cell, not vacuoles.
• synthesize molecules: Organelles like ribosomes, ER, or chloroplasts (in plants) synthesize molecules, not vacuoles.
• act as the control center of the cell: The nucleus is the control center, not the vacuole.
• export molecules: The cell membrane and Golgi apparatus are more involved in export, not vacuoles.

The endomembrane system includes organelles involved in membrane synthesis, modification, and transport: nuclear envelope, ER, Golgi, lysosomes, vacuoles, and cell membrane.

• Option 1 (Golgi apparatus, lysosomes, vacuoles, and the endoplasmic reticulum): All these are part of the endomembrane system.
• Option 2 (Golgi apparatus, lysosomes, mitochondria, and the endoplasmic reticulum): Mitochondria are not part of the endomembrane system (they have their own membrane system and are involved in energy production).
• Option 3 (Golgi apparatus, lysosomes, vacuoles, and cell wall): Cell wall is a structural component outside the cell membrane, not part of the endomembrane system.
• Option 4 (nucleus, lysosomes, vacuoles, and the endoplasmic reticulum): The nucleus is part of the endomembrane system (nuclear envelope), but this option is less accurate than Option 1 because the question asks for "only" endomembrane system organelles. However, the first option's components are all strictly part of the endomembrane system.
• Option 5 (Golgi apparatus, cytoskeleton, vacuoles, and the endoplasmic reticulum): Cytoskeleton is a network of protein filaments, not part of the endomembrane system.

Answer:

A. store molecules
