The leaves perform three main functions such as manufacture of food, interchange of gases between the atmosphere and the plant body and evaporation of water.

In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food.

Food vacuole are used by protozoans as temporary food store in the organism's protoplasm until it is required by the organism. Contractile vacuoles, on the other hand, are used by protozoans as means of expelling excess water and some waste out the protoplasm.

Vacuoles in both plant and animal cells serve as storage organelles inside the cell. The main difference between plant and animal vacuoles is that plant vacuoles are large in size and are single in number whereas animal vacuoles are small in size and are more in number.

plant cell has only one large vacuole that covers almost 90% cellular space sometimes. Plant cells needs larger vacuole because vacuole helps them to maintain turgor pressure within the cell. ... In animal cell the main function of vacuoles is to store nutrients ,ions and water.

Since vesicles are composed of a lipid bilayer, they can have a completely self-contained environment that is different from the inside of the cell. Thus, vesicles also function in metabolism and enzyme storage. It is involved in buoyancy control and temporary storage of food and enzymes.

Other than the fact that vacuoles are somewhat larger than vesicles, there is a very subtle distinction between them: the membranes of vesicles can fuse with either the plasma membrane or other membrane systems within the cell. The membrane of a vacuole does not fuse with the membranes of other cellular components.

The cell wall, chloroplasts and vacuole are found in plant cell rather than animal cells. These components are know as organelles of a cell and these organelles for a plant are vital for its functionality and survival.

The lysosomes are the animal cell's “garbage disposal”, while in plant cells the same function takes place in vacuoles. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane.

It has been likened to the cell's post office. A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.

['The main function of stomata is to open and close the pores in the leaves for an exchange of gases.', 'It allows the plant to take in carbon dioxide and give out oxygen for photosynthesis.', 'Based on the weather conditions, it closes or opens its pores to keep the moisture content developed.']

Central Vacuole Definition. The central vacuole is a large vacuole found inside of plant cells. A vacuole is a sphere filled with fluid and molecules inside a cell. ... Vacuoles are also found in animal, protist, fungal, and bacterial cells, but large central vacuoles are only found in plant cells.
