Study Notes
Here are the study notes for Cell Biology-V:
Cell Organelles
- Carotenoids and Chlorophyll: Carotenoids are present in chromoplasts, while chlorophyll is present in chloroplasts.
- Thylakoid: A thylakoid encloses a space called the lumen.
Ribosomes
- Size: Ribosomes are larger than cytoplasmic ribosomes.
- Location: Ribosomes are found in the cytoplasm, nucleus, and ER.
Lysosomes
- Function: Lysosomes are involved in digestion and are a part of the endomembrane system.
Endoplasmic Reticulum (ER)
- Functions: ER helps in transport of substances, synthesis of proteins, and formation of glycogen.
- Types: There are two types of ER: Rough ER (RER) and Smooth ER (SER).
Golgi Body
- Function: Golgi body is involved in protein synthesis, lipid synthesis, and formation of glycoproteins and glycogen.
- Structure: Golgi body has a cis face (forming face) and a trans face (mature face).
Mitochondria
- Function: Mitochondria are involved in aerobic respiration and are the site of cellular respiration.
- Structure: Mitochondria have an outer membrane and an inner membrane, with cristae (infoldings) increasing the surface area.
Cilia and Flagella
- Structure: Axoneme of cilia and flagella is made up of tubulin protein, and the basal body consists of 9 + 2 arrangement of microtubules.
Cell Cycle
- Metaphase: Chromosomes are arranged at the equator of the cell in metaphase.
- Anaphase: Sister chromatids separate and move to opposite poles in anaphase.
- Telophase: The nucleus, Golgi complex, and ER are reformed in telophase.
Centromere
- Function: The centromere is involved in the separation of sister chromatids during cell division.
- Splitting: Centromere splitting occurs in anaphase-II.
Cell Membrane
- Functions: Plasma membrane performs certain functions like growth, endocytosis, formation of intercellular junctions, and cell division.
- Fluid Nature: Plasma membrane represents fluid nature.
Glyoxisome
- Function: Glyoxisome is involved in fat metabolism.
Hydrolytic Enzymes
- Location: Almost all hydrolytic enzymes are present in lysosomes.
Cell Wall
- Function: Cell wall provides mechanical support, maintains cell shape, and protects the cell from external factors.
Prophase
- Events: ER is completely disappeared in prophase.
Let me know if you'd like me to add anything else!### Cell Cycle
- Quiescent stage of the cell cycle is permanently found in nerve cells (raf=kdk dksf'kdk).
Stages of Cell Cycle
- The stage between meiosis-I and meiosis-II is called interkinesis (baVjdkbusfll).
- Interphase (varjkoLFkk) is not the stage between meiosis-I and meiosis-II.
Duration of Cell Cycle Phases
- Interphase (varjkoLFkk) is the phase of the cell cycle that is completed in more than 95% of the cell cycle duration.
Cell Growth
- During interphase (varjkoLFkk), the volume of the cell increases to its maximum.
