How to draw diagram of Mature Embryo Sac And its 2, 4 and 8 Nucleate stages Class12

This video explains How to draw 2, 4 and 8 Nucleate Stages of Embryo Sac and a Mature Embryo sac class 12 science biology in easy steps and compact way. This video helps you to draw science diagrams with great ease and clarity.

•The formation of the female gametophyte from a single functional megaspore is called as monosporic development.
•The nucleus of functional megaspore divides mitotically to form two nuclei which move to opposite poles. This forms a two-nucleate embryo sac.
•Two more sequential mitotic nuclear divisions result in the formation of four-nucleate and eight-nucleate stages of embryo sac.
•These mitotic divisions are free nuclear type in which karyokinesis is not followed immediately by cytokinesis.
•After the eight-nucleate stage, the walls are laid down leading to the organization of the typical female gametophyte. Six of eight nuclei are surrounded by cell walls and organized into cells; the remaining two nuclei, called polar nuclei are situated below the egg apparatus in the large central cell.
•A typical angiosperm embryo sac at maturity is eight nucleate and seven cells. Three cells lie at micropylar end forming egg apparatus. Three ends at chalazal end called as antipodal cells. A single large central cell which has two polar nuclei.
