There are 2 vacuoles in plant cells.
Plant cells contain 2 functionally distinct vacuolar compartments which are "lytic vacuoles" for degradation and "protein storage vacuoles" for reserve accumulation.
Lytic vacuoles are acidic, hydrolytic compartments that are responsible for breaking down macromolecules.
Protein storage vacuoles accumulate proteins in storage organs such as seeds.
Humans cells and animal cells have more than 2 vacuoles and the exact number is not fully known.
The three main types of vacuoles are gas vacuoles, contractile vacuoles and food vacuoles.
Food vacuoles are formed by phagocytosis, where a cell engulfs solid food particles and they also contain digestive enzymes to break down the food.
Gas vacuoles are found in certain bacteria and cyanobacteria and contain gases, which help the organisms to float or adjust their buoyancy in water.
Contractile vacuoles are specialized vacuoles found in protists which help to regulate water balance by pumping excess water out of the cell and is a process called osmoregulation.
The enzymes that are involved in vacuoles is hydrolytic enzymes like hydrolases which are active at the acidic pH within the lysosome to break down various types of molecules.
Hydrolytic enzymes such as hydrolases are enzymes involved in vacuoles in humans and in plant cells the vacuoles contain a variety of hydrolytic enzymes, which include vacuolar processing enzymes, which are cysteine proteases, and acid hydrolases like alpha mannosidase, beta N acetylglucosaminidase, and beta fructosidase which are involved in several different processes which include cell death and degradation of cellular components.
Vacuoles are membrane bound organelles that are found in both plants and animals.
And in a way vacuoles are specialized lysosomes which means the function of the vacuoles is really to handle waste products and essentially means that it takes in waste products and gets rid of the waste products.
In human cells, vacuoles are membrane organelles that are similar to lysosomes which primarily function in waste management and storage although the vacuoles play a less prominent role when compared to their counterparts in plant cells.
Vacuoles store nutrients and water on which a cell can rely for its survival.
The vacuoles also store the waste from the cell and prevents the cell from contamination.
Food vacuoles (also called digestive vacuole) are organelles found in certain protists, such as ciliates, amoeboids and Plasmodium falciparum, a protozoan parasite that causes malaria.
Food vacuoles have a single-layered membrane, known as a plasma membrane, that is composed of a phospholipid bilayer.
Food vacuoles are found in all eukaryotic cells of organisms such as protists, animals, and plants.
Vacuolar processing enzyme (VPE) functions in the activation of various types of proteins in the vacuole.
VPE can self-activate in the vacuole.
After the activation, VPE cleaves precursors of vacuolar proteins to their active forms.
Vacuoles, which are membrane-bound compartments within cells, contain a fluid called cell sap, which is a solution of water, salts, sugars, and other dissolved substances, and can also store waste products and pigments.
