4. Endoplasmic Reticulum (এন্ডোপ্লাজমিক রেটিকুলাম) Has ribosomes (Protein synthesis). Smooth (SER): No ribosomes (Lipid synthesis). 5. Golgi Bodies (গলজি বস্তু) Function: Packaging and secretion of substances. 6. Lysosomes (লাইসোজোম)
Complex tissues consist of more than one type of cell working together as a unit to conduct materials. 1. Xylem (Water Conduction)
A dead/non-living outer layer unique to plant cells, primarily made of cellulose, hemicellulose, and lignin. 2. Cytoplasmic Organelles & Functions ssc biology chapter 2 hand note exclusive
The branch of biology that studies the structure, function, and chemistry of cells.
Blood (composed of plasma, transport-focused Red Blood Cells, immune-focused White Blood Cells, and clotting-focused Platelets) and Lymph (filtered tissue fluid essential for immunity). Muscular Tissue transport-focused Red Blood Cells
An organelle located near the nucleus containing a pair of centrioles. It plays a critical role in forming the spindle apparatus during animal cell division (mitosis).
Spindle-shaped, single nucleus, lacking striations. Controlled by the autonomous nervous system (e.g., Alimentary canal walls). immune-focused White Blood Cells
Remember that Xylem conducts water (think "Xy" sound similar to "water physics" or "high to low"), while Phloem conducts food ("Ph" sounds like "F" for food).
