Found beneath the skin, binding tissues together.

Contain green chlorophyll; execute photosynthesis.

Cells that possess the continuous capability of mitotic division. They are characterized by thin cell walls, dense cytoplasm, large nuclei, and an absence of intercellular spaces or vacuoles. They drive primary and secondary plant growth. 2. Permanent Tissue

To maximize your score in both Multiple Choice Questions (MCQs) and Creative Questions (CQs), keep these insights in mind:

Colored plastids (yellow, orange, red) containing carotenoids. They give color to flowers and fruits to attract pollinators. ssc biology chapter 2 hand note exclusive

Organelles are specialized cellular structures that perform distinct metabolic functions. 1. Unique Structures of Plant Cells

Skin, lining of the mouth, intestines, kidney tubules. Types: Squamous, Cuboidal, Columnar, Stratified. B. Connective Tissue Function: Binding, supporting, and transporting materials. Components: Cells + Matrix (ground substance). Types: Blood: Fluid connective tissue (plasma + blood cells). Bone/Cartilage: Skeletal tissue (provides framework). Areolar/Adipose: Binding and fat storage. C. Muscular Tissue Function: Movement. Types: Striated (Voluntary): Attached to bones (skeleton).

Tall, pillar-like cells with basal nuclei (e.g., inner lining of the intestine). Specialized for absorption and secretion.

Living cells with localized pectin and cellulose thickening at the corners. Found beneath the skin, binding tissues together

Found in walls of internal organs (stomach, blood vessels). Cardiac (Involuntary): Found only in the heart. D. Nervous Tissue Function: Transmission of stimuli (impulses). Unit: Neuron (Cell body, Axon, Dendrites). 3. Plant Tissues (Exclusive Classification)

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)

Possess a well-defined nucleus (e.g., Plant and Animal cells). Based on Function: Somatic Cell (দেহকোষ): Forms the body.

Found in plants; Chloroplasts are essential for photosynthesis. Ribosomes: Sites for protein synthesis. They are characterized by thin cell walls, dense

Focus on the microscopic study of tissues to understand their specialized roles in organ systems.
