During germination, the testa, or seed coat, often remains intact for a period of time but may eventually split or break apart as the seedling emerges. The primary function of the testa is to protect the seed during dormancy, and it can sometimes hinder the germination process if it is too tough. However, in some seeds, the testa may soften or be breached by the growing embryo, allowing the seed to sprout. Overall, the fate of the testa during germination varies depending on the species of plant.
What else can I help you with?
What are tiny holes in the testa?
Tiny holes in the testa, called micropyles, act as passages for water to enter the seed for germination. They also allow for the exchange of gases during respiration in the seed.
Is the testa in plants the seed coat?
Yes, the testa in plants is the outer seed coat that protects the embryo within the seed. It acts as a protective layer and helps regulate water and gas exchange during seed germination.
Of what importance is a testa to a seed?
The importance of a testa to a seed is to protect it from adverse environmental conditions.
Which tissues are present in hard covering of seeds?
The hard covering of seeds is primarily composed of the seed coat, which is made up of specialized tissues like the testa and the tegmen. These tissues provide protection to the seed during dormancy and help regulate water intake when germination occurs. Additionally, the endosperm or cotyledons found within the seed also contribute to the overall structure of the seed coat.
What is the function of the seed coat?
if there is no seed coat the see won't grow

What is the part of a plant that grows around the seed?
The part of a plant that grows around the seed is called the seed coat. It protects the seed and helps regulate water and gas exchange during germination.
What is the outer covering of a seed called?
The outer covering of a seed is called the seed coat. It protects the embryo inside and helps regulate the exchange of gases and water during germination.

What are some characteristics of seeds?
They are covered by a hardened seed coat called a testa. They contain a diploid embryo or zygote. They are nourished by a single (monocotyledonous) or double (dicoltyledonous) tissue; this/ these cotyledon(s) become the first primary leaves on germination. Seeds are contained in the ovary (or fruit) until ripe (although there are few exceptions). Seed can remain viable (for germination) from anywhere between 30 days and 100 years - there is a recent example of a 30,000 frozen seed (Siberia) being sucessfuly germinated (Feb 2012)
