Question

a large, membrane - bound sac that stores water, nutrients, and waste products is a prominent feature of most mature plant cells. this organelle is the: large central vacuole lysosome golgi vesicle small vacuole both prokaryotic and eukaryotic cells contain which of the following structures responsible for protein synthesis? ribosomes cell wall mitochondria nucleus

Explanation:

1. The large, membrane - bound sac that stores water, nutrients, and waste products and is prominent in most mature plant cells is the large central vacuole. Lysosomes are involved in digestion, Golgi vesicles are related to the Golgi apparatus for transport, and small vacuoles are not the main storage organelle in mature plant cells.
2. Ribosomes are the structures responsible for protein synthesis in both prokaryotic and eukaryotic cells. The cell wall provides structural support, mitochondria are for energy production, and the nucleus contains genetic material.

Answer:

1. Large central vacuole
2. Ribosomes
