Fueling Plant Growth: Endosperm Quiz Mastery

This assessment explores the role of endosperm in plant growth, evaluating knowledge of its functions, development, and significance. Understanding endosperm is crucial for students and professionals in botany and agriculture, as...

Questions: 15 | Attempts: 10 | Last updated: Mar 19, 2026

Sample Question 1
What event gives rise to the endosperm during the development of flowering plant seeds?

The fusion of one sperm cell with the two polar nuclei in the central cell of the embryo sac, forming a triploid (3n) nucleus

The fusion of the sperm cell with the egg cell to produce the diploid zygote

The division of the integuments surrounding the ovule after fertilization

The development of the nucellus tissue into a nutritive layer after pollination

Sample Question 2
What is the ploidy level of the endosperm in most flowering plants, and why is this significant?

Haploid (1n), because it is derived from a single polar nucleus

Diploid (2n), because it results from the fusion of two identical cells

Polyploid (6n), because three sets of polar nuclei are always involved

Triploid (3n), because it arises from the fusion of two polar nuclei (2n) with one sperm nucleus (1n)

Sample Question 3
The endosperm is the primary nutritive tissue in seeds of flowering plants and supplies the embryo with carbohydrates, proteins, and lipids during germination.
