What is a central vacuole in a cell? The central vacuole is a large vacuole found within plant cells. A vacuole is a sphere filled with liquid and molecules within a cell. The central vacuole stores water and maintains turgor pressure in a plant cell. It also pushes the contents of the cell to the … Read more
Rough Endoplasmic Reticulum The rough endoplasmic reticulum (ER rough) is part of the cell’s endomembrane system and a subset of the endoplasmic reticulum (ER). This organelle is mainly concerned with the synthesis, folding, and modification of proteins, especially those that have to be delivered to different organelles within the cell or secreted by the cell. … Read more
What is exocytosis? As compared to endocytosis, exocytosis is a process that is used to use energy to move materials from inside the cell to the outside of the cell. Therefore, it is a kind of active transport mechanism and the opposite of endocytosis. Generally, in this exocytosis mechanism, a special vesicle attached to the cell … Read more
Definition of Endocytosis Endocytosis is a cellular mechanism by which a cell internalizes substances such as proteins, fluids, electrolytes, microorganisms, and certain macromolecules from its external environment. These substances are subjected to certain processes of decomposition into smaller elements, either for use by the cell or for elimination. White blood cells of the immune system … Read more
Define Trabeculæ carneæ Define Trabeculæ carneæ, The trabeculæ carneæ (columnœ carneœ) are rounded or irregular muscle columns that protrude from the entire inner surface of the ventricle except for the conus arteriosus. What are the types of trabeculæ carneæ There are three types: some are attached along their entire length on one side and form … Read more
Define Plant cell, 7 Parts, structure, and Its function of plant cell Define Plant cell Cells are the basic building blocks of all living things. They differ in size, shape, and function. There are similarities in the formation of the plant and animal cells, such as cell membranes, cell plasma, and cell nuclei. In-plant cells, … Read more
What is a eukaryotic cell? Eukaryotic cells (from the Greek word Eukaryota, the union of EU – “true” and karyon “nut, nucleus”) are called all cells in whose cytoplasm a precisely defined nucleus can be found that contains most of their genetic material (DNA ). In this, they differ from prokaryotic cells, which are much … Read more
What are single-celled organisms? Unicellular organisms It is called a unicellular organism for all life forms whose body is made up of a single cell and which do not form any kind of tissue, structure, or joint body with others of their kind. In other words, they are microscopic beings whose body is a single … Read more
What is Cytosol? |Definition of cytosol Cytosol can be defined as the cytosol is the fluid inside the cells. It is the water-based solution in which organelles, proteins, and other cellular structures float. The cytosol in any cell is a complex solution, whose properties allow the functions of life to take place. The cytosol contains proteins, amino acids, mRNA, … Read more
Animal cells and plant cells have several differences and similarities. For example, animal cells do not have cell walls or chloroplasts, while plant cells do. Animal cells are mostly round and irregular shapes, while plant cells have a fixed rectangular shape. Animal and plant cells are eukaryotic cells, so they have some common features, such … Read more
