Answer: Vacuole
Explanation:
The vacuole occupies on average 50% of the cell volume, oscillating between 5 and 95%. It is a fluid-filled, membrane-wrapped gallbladder. The vacuoles perform numerous functions because, in addition to accumulating nutrients, metabolites, and catabolites, they serve as deposits of specific substances such as proteins, opium, dairy and also various poisonous or unpleasant taste substances, which protect the plant against its predators.
Vacuoles are structures that participate in the maintenance of cell turgor, which pulls the cytoplasm against the cell wall as air tightens the air chamber against the tire. When water is lacking, the plant wilts due to decreased intracellular turgor.
The plant cell organelle which helps in maintaining the shape of the cell by maintaining turgor pressure is vacuole.
Further Explanation:
The vacuole is an organelle which is mainly present in animal and plant also. There is a difference in size of plant and animal vacuole. Plant cells contain vacuole in the centre of the cell which is much larger than the animal vacuole. Animal cells contain multiple vacuoles that are scattered in the cytoplasm of the cell. They contain membrane-bound sacs. The cell membranes of vacuoles are made up of phospholipids. Proteins are embedded in the cell membrane to transport small molecule. Most plant cells use vacuoles to store water. Animals don’t use vacuole as water storage they store product for endocytosis and exocytosis.
The major functions of vacuoles are:
Manly in plants, a large vacuole is present. This vacuole is enclosed by a cytoplasmic membrane which is tonoplast. This layer can easily stretch and fill with solution. They can easily fill with proton and create acidic environment inside the cell. The development of chemical gradient is helps in transporting material inside and outside of vacuole. They use proton motive force to transport molecule. The vacuole when filled completely with water exerts a pressure on walls of cells called turgor pressure. These force help in maintaining the shape of the cell. Also, allow cells to stand up in rain, wind and hail.

Red blood cells lack a nucleus and have limited organelles, allowing more space for carrying oxygen. They have a unique biconcave shape, short lifespan, and cannot undergo cell division. Their specialization lies in oxygen transport, making them highly efficient in their function.
Red blood cells (RBCs), or erythrocytes, are disk shaped blood cells without a nucleus and most organelles. Their main role is to transport oxygen throughout the body, facilitated by the protein hemoglobin. Hemoglobin binds to oxygen in the lungs and releases it to body tissues.
Due to hemoglobin, RBCs appear red and give blood its color. They have a lifespan of about 120 days and are continually replaced in the bone marrow. RBCs are vital for maintaining proper oxygenation of tissues and supporting metabolic functions.
Their unique structure and function make them essential components of the circulatory system in vertebrates, including humans.

c. rojo
d. morado
Answer:
whichever solution has a lower concentration of the solute in it will lose volume as in osmosis water is attracted to the side with a higher volume of the solute
