What Is The Primary Function Of A Cell Membrane – An animal cell is a eukaryotic cell that lacks a cell wall and is enclosed by a plasma Membrane. Cell organelles are enclosed by a plasma membrane including the cell nucleus. Unlike an animal cell that lacks a cell wall, plant cells have a cell wall.
An animal cell is composed of several structural organelles enclosed in a plasma membrane, which allow it to Function properly, triggering mechanisms that benefit the host (animal). The joint work of all cells gives the animal the ability to move, to reproduce, to react to stimuli, to digest and absorb food, etc. In general, the combined effort of all animal cells is what allows the body to function normally.

Variations in physical and functional characteristics distinguish ER into two types, viz. rough endoplasmic reticulum and smooth endoplasmic reticulum.
What Are Stem Cells & How Do They Impact Modern Medicine?
It is also known as cellular vesicles; Lysosomes were discovered by Christian Rene de Duve, a Belgian cytologist in the 1950s.
This is clearly found in the animal cell, which has the ability to replicate or make copies of itself. It consists of 9 bundles of microtubules and their primary function is to help organize the process of cell division.
These are vesicles bound by membranes and formed by the mechanism of endocytosis. They are located in the cell cytoplasm.
These are surface protrusions found in the intestinal mucosa, on the surfaces of egg cells and on white blood cells.

Faith Mokobi is a passionate scientist and graduate student currently working on her Ph.D. degree in nanoengineering (specialization in synthetic biology) at the Joint School of Nanoscience and Nanoengineering, North Carolina A and T State University, North Carolina, USA. He has an education in immunology and microbiology (MSc./BSc.). With extensive experience in higher education teaching and research in biomedical studies, metagenomic studies and drug resistance, Faith is currently integrating her biomedical experience in nanotechnology and cancer theranostics. The Golgi apparatus, also known as the Golgi body or Golgi complex, is a type of organelle (ie, a structure located in a cell) that processes and packages proteins and lipid molecules (ie, fat molecules). They are subsequently transported to other cellular compartments (for example, lysosomes or the plasma membrane) or secreted from the cell.
When Camillo Golgi discovered the Golgi apparatus in 1898, it was one of the first cell organelles discovered. He discovered it while researching the nervous system. Camillo Golgi called his discovery the “inner reticular apparatus”, and the organelle was named after him only in 1910.
The Golgi apparatus is a series of stacked membranes found within the cytoplasm (ie, the gel-like fluid found in the cell membrane) in all eukaryotic cells (ie, complex cells). It can usually be found near the nucleus and rough endoplasmic reticulum (organelles involved in protein synthesis).
The function of the Golgi apparatus is to process and package proteins that have left the rough endoplasmic reticulum for further transport inside and/or outside the cell. In plant cells, the Golgi body also serves as a site for the synthesis of complex polysaccharides.
Cell Review For Biology I
The Golgi body contains Golgi stacks, which can be thought of as a series of trafficking pathways that work by modifying proteins and other complex polysaccharides. The number of Golgi stacks a cell has depends largely on the cell type. These Golgi stacks contain from 3 to 20 flattened membrane sacs, called cisternae. These Golgi cisternae are usually classified based on what they import and export to the Golgi body, each containing a different set of processing enzymes. Therefore, Golgi cisternae are a very important part of the packaging and processing that takes place in the Golgi body.
Transport vesicles usually pick up molecules from the rough endoplasmic reticulum and transport them to the cis face (ie, the region of the Golgi apparatus adjacent to the endoplasmic reticulum) of the Golgi stacks, where they fuse with the Golgi membrane and are sorted based on their next destination. They are then moved through Golgi cisternae as they undergo remodeling and other modifications. The modified protein or lipid molecules then leave the transface (ie, the area of the Golgi apparatus facing the plasma membrane) of the Golgi stack where they are either secreted from the cell, or transported to another cell compartment.
The complex network of membranes and vesicles in the Golgi stacks into which molecules enter is also known as the cis Golgi network.
The Golgi apparatus, also known as the Golgi body or Golgi complex, is an organelle that processes and packages proteins and lipid molecules (i.e., fat molecules) that are later exported to other cellular compartments or secreted from the cell.
