The correct answer to the question above is central vacuole. Central vacuole is the plant cell structure that stores large amounts of chemicals which includes salts, minerals, proteins, and water for the plant cell, and helps the cell to maintain its shape.
Well quiet naturally both animal and human testing are both very controversial and involve great deal of ethics.
Answer:
Desmosomes
Explanation:
Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.
