CELL STRUCTURE
da Desiree M. Aguilar
1. PLASMA MEMBRANE
1.1. protein are embedded in phospholipid bilayer
1.2. semi-permeable or selective permeable
1.3. encloses the cytoplasm or protoplasm of the cells
2. RIBOSOMES
2.1. synthesized protein molecules
2.2. an assembly of two ribosomal RNA (rRNA) that are synthesized in nucleus
3. LYSOSOMES
3.1. cotains hydrolytic enzymes
3.2. also digest the remains of dead organelle (autolysis process)
4. ENDOPLASMIC RETICULUM
4.1. Rough Endoplasim Reticulum (RER)
4.1.1. synthesizing protein, modifying, packaging and transport of secretory proteins
4.2. Smooth Endoplasmic Reticulum
4.2.1. diverse metabolic activities
5. CHLOROPLAST
5.1. enclosed by two membranes separated by intermediate space
5.2. have their own DNA, RNA and ribosomes
6. CELL WALL
6.1. maintains the turgidity of cells
6.2. provides strength and gives mechanical support
6.3. maintains the shape of the cell
7. NUCLEUS
7.1. store genetic material in the form of DNA
7.2. largest and most prominent organelle
7.3. Nucleolus
7.3.1. to synthesize ribosomal RNA subunits for the protein synthesis
