Oogenesis (55x90cm)

An Oogenesis chart (55×90 cm) is a large, full-color educational wall poster illustrating the entire process of female gamete (egg cell) development, ideal for biology, NEET/medical prep, and advanced classroom instruction.​

Chart Features and Content

Chart Size and Material: 55 × 90 cm, printed on durable laminated paper for classroom and laboratory longevity. Clearly organized flow diagrams support visual learning.​

Oogenesis Process Diagram: The chart visually breaks down the three main stages:

Multiplication phase: Oogonia (2n) formed via mitosis from primordial germ cells, increasing precursor numbers.

Growth phase: Oogonia mature into primary oocytes, growing in size, accumulating nutrients and organelles.

Maturation phase: Primary oocyte undergoes meiosis I, producing a large secondary oocyte (n) and a small first polar body. Meiosis II occurs in the secondary oocyte—completing only after fertilization—to yield an ovum (n) and second polar body.​

Detailed Labeling: Diagrams label all cell stages: oogonium, primary oocyte, secondary oocyte, polar bodies, ovum. Arrows and annotations describe DNA content changes (2n→n), cytoplasmic division, and follicular development.​

Functional Annotations: Side panels or boxed notes clarify hormonal regulation (FSH, LH), timing (embryonic arrest, puberty, ovulation), and clinical correlates (follicle structure, relevance for reproduction or infertility studies).​

Comparative Notes: Some charts briefly contrast oogenesis with spermatogenesis for conceptual clarity.​

Institutional and Catalog Use

Used for higher secondary, NEET/medical studies, and university biology/zoology curricula—helping visualize cell divisions and the significance of polar bodies.

Sold by educational chart producers and academic retailers, and often downloaded for digital inclusion in teaching kits and catalogs.​

For catalog and instructional use, select charts with scientifically accurate labeling, high-contrast color coding of each cell stage, and clear indications of meiotic events.
