Flashcards
Two-cell stage
Two-cell stage
Asymmetric cell division marks this stage.
Apical cell
Apical cell
This cell lineage leads to the upper part of the plant, including the shoot and leaves.
Basal cell function
Basal cell function
It anchors the embryo and aids in nutrient transfer; forms hypophysis and suspensor.
