Answer:
Compound Umbel.
Step-by-step explanation:
Celery is more of an annual crop which is a herbaceous plant usually 60 to 120 cm high with white Flowers.
The Celery plant belongs to the Apiaceae and they are known to be mainly Annual.
Morphology or the shape of the Celery plant is that of a Compound Umbel, in which all Umbel inflorescences arises from a common point and appears to be at the same level.They change from
elongated axes (racemes and panicles) to flattened axes (corymbs and umbels) which results in inflorescences thereby making the flowers been arranged closely together. This close association encourages efficient pollination,and the extreme condensation of the inflorescences, as in the
head, gives rise to an inflorescence that appears
to be a single flower and example of such happen to be the sunflowers commonly found around us.
