Answer: Give an example of unicellular organism. اس کے بیج تیل نکالنے کے کام آتے ہیں. Whereas, in RBC the movement of water inside the cell due to osmosis will lead to bursting of the cell because it does not have a rigid cell wall. Therefore, these are largely present in secreting cells. It helps in the formation of cell plate during cell division. What do you mean by plasmodesmata? After modification, these are transported to the cell surface through vesicles which bud off from Golgi complex to fuse with cell membrane and form a part of the membrane. The main function of Golgi bodies is to release proteins or enzymes by vesicles. سیل بائیولوجی میں سیل کی تقسیم یعنی سیل کی ڈویژن کا مطالعہ بھی کیا جاتا ہے. When salt is added, a hypotonic medium is created, i.e., the concentration of salt molecules is more outside the vegetables than inside. انھوں نے عراق میں علم طب کی پریکٹس کی.ان مشہور کتاب" النباتات"اور الحیوان ہیں. زولوجی (اس ڈویژن میںجانوروں کا سائنسی علم حاصل کیا جاتا ہے)

Ribosomes are found in greater number in actively dividing cells which are the cancer cells as they need more amount of proteins for the formation of new cells. (e) golgi apparatus is removed from the cell? Mathematically, M = P1 × P2, where Pi is the power of eyepiece andP2 is the power of objective. Question 6. Question 12. Question 10. 2. Answer: Which organelle is involved in the formation of lysosomes? زولوجی:
Which organelle is associated with ribosome formation? [NCERT Exemplar] For example, DNA from the nucleus passes the information for protein formation to the ribosomes which send the proteins to Golgi complex and ER for modification and transport. Draw a labelled diagram of mitochondria. Answer: NCERT Solutions for Class 6, 7, 8, 9, 10, 11 and 12, Extra Questions for Class 9 Science Chapter 5 The Fundamental Unit of Life. ??. پیراسائیٹولوجی: پیراسائیٹولوجی ایسی شاخ ہے جس میں پیراسائیٹس کا مطالعہ کیا جاتا ہے.
