It is a qualitative increase in size of a cell (3 micrometer - 5 micrometer)
Hypertrophy
It is a quantitative increase in number of cells (10 cells - 15 cells)
Hyperplasia
Transformation of one type of cell to another (cuboidal - columnar)
Metaplasia
Reinversion of a cell to a more primitive and undifferentiated cell type.
Anaplasia
Abnormality in size, shape, and orientation of cell.
Dysplasia
Abnormality in cell structure; hallmark of tumor and cancer cells
Neoplasia
Collective term for different substances that make up a cell. A bacterial, fungi, or plant cell that has had its cell wall completely or partially removed using either enzymatic or mechanical means
Protoplasm
What makes up protoplasm?
- H20/water
- Protein
- Fats/Lipids
- Carbohydrates
- Electrolytes
The principal fluid medium of the protoplasm consisting (70%-80% cell mass)
H2O/Water
2nd most abundant substance (10%-20% cell mass)
Protein
What are the 2 types of protein and their description?
Fibrous Protein - Fibrilar form
Globular protein - Has individual protein molecules/Globular
Phospholipid and cholesterol are the most important part of the cell (2% cell mass).
Lipids/Fats
What is the storage form of lipids or fat in the cell?
Triglycerides or neutral cells
Little structural function but provide most of the nutritional requirement of the cell
Carbohydrates
Simplest form of the carbohydrates and it is use for cellular metabolism and energy production.
Glucose
Storage form of carbohydrates and usually stored in liver and skeletal muscle.
Glycogen
Inorganic chemical for cellular respiration. And what are the 2 types of it?

What are the examples of anion?
- Chloride (Cl-)
- Sulfate (SO4)
- Phosphate (PO4)
- Bicarbonate (HCO3)
2 Types of Cells and their definition
- Somatic cells - all cell in the body except germ cells; undergoes Mitosis which results in diploid (2n) chromosomes.
- Germ/Sex Cells/Gametes - sperm cell and egg cells’ undergoes Meiosis which results in haploid (n) chromosomes.
What are the 2 phases of Cell Cycle?
- Interphase - the longest phase of the cell cycle
- Cell Division
- Before DNA Synthesis
- During DNA Synthesis
- After DNA Synthesis
- G1 Phase
- S Phase
- G2 Phase
What is the correct arrangement of cell division?
PMAT (Prophase, Metaphase, Anaphase, Telophase)
Condensation of nuclear material, nucleolus and nuclear membrane disappearance.
Prophase
Chromosomes line up along the equatorial plate
Metaphase
Sister chromatids attaches to spindle fibers and moves toward the opposite poles
Anaphase
2 daughter cells are formed, nuclear membrane and nucleolus reappearance.
Telophase
Outer permeable layer of the cell
Cell membrane
Boat/sausage shaped organelle; Krebs cycle is involved wherein it produces 36 ATP
Mitochondria
Contains fluid medium (cytosol); suspends the organelle
Cytoplasm
Contains hydrolase; contains an array of degradative enzymes which breakdown almost all the biological polymers inside the cell.
Lysosome
It contains oxidose, an enzyme which carry out oxidation reactions and breakdown metabolic hydrogen peroxide
Peroxisome
Has ribosomes embedded on it. Its main function is to synthesis proteins
Rough Endoplasmic Reticulum (RER)
Synthesizes lipids, steroids, and carbohydrates
Smooth Endoplasmic Reticlum (SER)
Crescent/half moon shaped; packaging center of the cell which packages the protein and other substances from RER and SER
Golgi Apparatus
Helps in and guides spindle fiber during meiosis and mitosis
Centriole
