Outer parts of both phospholipid layer is a hydrophilic part (i.e soluble in water). |
Inner part of both phospholipid layers form the middle part - hydrophobic part (i.e not soluble in water). |
Protein present through the vertical length of membrane → called as integral protein (transmembrane protein) |
Protein present in the inner aspect of the membrane near the transmembrane protein called → peripheral protein. |
Similarly, it consists of carbohydrate molecules as glycoprotein and glycolipid commonly called as glycocalyx.
|
• It forms the boundary of the cell. |
• Maintains the shape of the cell. |
• Acts as a selective barrier that regulates the passage of certain materials into or out of the cell. |
• Serves as the site of the receptor (protein act as receptor). |
• Limits the protoplasmic content of the cell. |
Organelles: | Inclusions: |
• Permanent components of cell | • Temporary components |
• Highly organized physical Structure | • They are raw food materials or product of metabolism |
• Eg. Mitochondria, ER, Golgi bodies | • Eg: Secretory granules, pigment, CHO, Protein |
DNA | RNA |
• Double-stranded | • Single-stranded |
• Found in nucleus (99%), mitochondria (1%) | • Found in the cytoplasm (90%), nucleus (10%.) |
• nitrogen bases are Adenine, Guanine, cytosine, Thymine | • Nitrogen bases are Adenine, Guanine, cytosine, Uracil |
• Contain deoxyribose sugar | • Contain ribose sugar |
• Sum of purine bases is equal to the sum of pyrimidine bases. | • Sum of the purine base is not equal to the sum of pyrimidine bases. |
• Function Carry genetic information. |
• Function: Translate genetic information of DNA into protein |
• Histone protein present. | • Histone protein absent. |
• Polymer of deoxy-ribonucleotides | • Polymer of ribonucleotides |
