Use terms like Semi-permeable , Cristae , Lignified , and Fluid Connective Tissue in your answers.
A group of cells having a similar structure and performing a specific function is called a tissue.
Composed of neurons (nerve cells) specialized to receive, process, and transmit electrochemical impulses.
: Large and central in plant cells; small or absent in animal cells.
A group of similar cells performing a common function is called tissue. Animal tissues are classified into four main types: A. Epithelial Tissue Protection, absorption, secretion. ssc biology chapter 2 hand note exclusive
The semi-fluid matrix where cellular metabolic reactions occur.
Complex Tissue: Xylem (transports water), Phloem (transports food). B. Animal Tissue (প্রাণী টিস্যু)
A tissue is a group of cells sharing a common origin, structure, and function. Plant tissues are broadly divided into Meristematic and Permanent tissues.
SSC Biology Chapter 2 Hand Note Exclusive: Cells and Tissues Use terms like Semi-permeable , Cristae , Lignified
Smooth ER synthesizes lipids; Rough ER (studded with ribosomes) transports proteins.
: Exclusive to plant cells. They include Chloroplasts (photosynthesis), Chromoplasts (colored pigments for flowers/fruits), and Leucoplasts (storage of starch and oils).
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).
Found only in plants. Chloroplasts (green) are for photosynthesis, Chromoplasts (colored) attract pollinators, and Leucoplasts (colorless) store food. 2. The Nucleus: The Control Center A well-developed nucleus consists of: Nuclear Membrane: The outer boundary. Nucleoplasm: The fluid inside. Nucleolus: The dense body that synthesizes ribosomes. : Large and central in plant cells; small
Consists of a cell body ( Soma ), short branched projections ( Dendrons ), and a long single conduction thread ( Axon ). 5. High-Yield Exam Tips for Board Exams
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.
of the cell; responsible for ATP (energy) production and contains its own DNA. : Found only in plant cells: Chloroplast : Site of photosynthesis; contains green chlorophyll. Chromoplast : Provides color to flowers and fruits. Leucoplast : Stores starch, oils, and proteins. : Often called "suicidal bags"
For , an "exclusive hand note" typically highlights core cellular structures, tissue types, and their functional differences. Based on educational resources from platforms like Scribd and academic guides, a comprehensive hand note feature should include: 1. Cell Basics & Theory
: A double-membrane envelope containing chromatin and the nucleolus, the site of ribosome production.
