Anatomically cell is divided into

Anatomically cell is divided into 3 parts, namely:

    
Plasma membrane (cell membrane, plasma membrane or also called plasmalema)
    
Cytoplasm and cell organelles
    
Cell nuclei (nuclei)

1. The cell membrane
Cell membranes limit any activity that occurs in cells that are not easily distracted by outside influences. Because of this function, the cell membrane is selektifpermaebel can specify certain materials are able to enter and exit the cell. In plant cells, the cell membrane normally attached to the cell wall due to turgor pressure of the cell.
2. Cytoplasm
The main function of life takes place in the cytoplasm. Almost all metabolic activities take place in a room containing a viscous fluid is. In the cytoplasm there are organelles floating in a viscous fluid (a colloid, but not homogeneous) is called the matrix. Organellah that perform many functions of life, baha synthesis, respiration (recast), storage and reaction to stimuli. Most of these processes occur within the enzymatic sitoplama set. In addition to organelles, there are vacuoles, starch grains, silicate grains and various other secondary products.
3. The nucleus (the cell nucleus)
Nucleus charge of controlling the activities that occur in the cytoplasm. Inside the nucleus are chromosomes that contain DNA that is the blueprint for the establishment of a variety of proteins (particularly enzymes). The enzyme is required in performing various functions in the cytoplasm. Disalam nucleolus nucleolus also present.
4. Organelles
Humans have many differe
