What is a central vacuole in a cell? Function, and Role

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

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? Exocytosis mechanism

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, and Process of Endocytosis

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

What is a eukaryotic cell? Types, Functions, and parts

What is a eukaryotic cell? Types, Functions, and parts

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 is Cytosol? | Definition of cytosol

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

Plant Cells and Animal Cells-Differences and Comparisons, and Diagram

Plant Cells and Animal Cells-Differences and Comparisons, and Diagram

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
