Nasal cavity, trachea, and lungs facilitating gas exchange.
Expect questions like "Difference between Xylem and Phloem" or "Prokaryotic vs. Eukaryotic cells."
1. Mitochondria (মাইটোকন্ড্রিয়া) - Exclusive Note
While similar to plant cells, Animal Cells have distinct differences: ssc biology chapter 2 hand note exclusive
Network of membranes; transports materials. Rough ER: Has ribosomes (protein synthesis). Smooth ER: No ribosomes (lipid synthesis). Ribosomes: Protein factories. Golgi Bodies: Packaging and secretion of materials.
A system of membranes that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
Animal tissues are classified into four primary types based on structure, location, and function. Epithelial Tissue Nasal cavity, trachea, and lungs facilitating gas exchange
This is the most important part of your . For board exams, they love asking for differences between organelles.
A tissue is a group of cells sharing a common origin, structure, and function. Plant tissues are broadly categorized into Meristematic (dividing) and Permanent (non-dividing) tissues. Permanent tissues are subdivided into simple and complex forms. A. Simple Tissues
A group of cells having a similar structure and performing a specific function is called a tissue. Ribosomes: Protein factories
Remember the name Robert Hooke (discovered cells in cork, 1665) – this is a common MCQ.
: Epithelial (covering), Muscular (movement), Nervous (coordination), and Connective (support). 5. Essential Exam Topics
Spindle-shaped, single nucleus, no bands. Works automatically (e.g., walls of blood vessels and alimentary canal).
Secretes enzymes and hormones and packages materials into vesicles.
Tendons (attaching muscle to bone) and Ligaments (attaching bone to bone). Muscular Tissue Responsible for locomotion and internal body movements.
