Introduction:
Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. The nucleus is bound by a nuclear membrane, and it possesses the genetic material of the cell. Cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. Protoplasm denotes all living material that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus).

- ______transport (general term)uses the energy of Browain motion associated with gradients to move materials from one place to another without the use of "cellular energy".A specific example of this type of transport is ‐-----------arrow_forwardWhich type(s) of vesicular transport is for nonspecific engulfment of fluid and materials from outside of the cell? a receptor-mediated endocytosis b exocytosis c pinocytosis d phagocytosis and pinocytosisarrow_forwardThe extracellular matrix is composed mainly of?arrow_forward
- Secretory vesicles fuse with the cell membrane to release their contents to the outside of the cell. In this process, the membrane of the secretory vesicle becomes part of the cell membrane because small pieces of the membrane are continually added to the cell membrane, one would expect the cell membrane to become larger and larger as secretion continues. The cell membrane stays the same size, however. Explain how this happens.arrow_forwardFunctions of cell membrane as traffic regulator, bidirectional and in term of concentration gradientarrow_forwardwhat carries products secreted from the golgi to the plasma membranearrow_forward
