The spores are protected by hard protective coat because the environment the spores might land, is not that very friendly. And the function of that covering is to protect the spore.
Science is not that hard just study and work hard! For me it comes really easy.
How hard they are. And if they are from Canada or the USA.
The floor is very hard.
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
i think it is hard and heavy so its hard to wear
Advantages - Spores are covered by a hard protective coat which enables them to survive under unfavourable conditions like lack of water and extreme temperatures. But when the conditions are favourable, the spores grow to produce new plants. This help them to run their species at any type adverse condition or environment. Thus the advantage is that despite of unfavourable environment, their species will not be demolished.Disadvantages - spore formation process is quite primitive.

ANSWER:Mushrooms don't have seeds, they have spores. You can get mushroom spores by tapping a mature mushroom and collecting the spores to transfer to another growth medium. They are very minute and hard to see.

The seed coat is hard protective covering of the seed, developed from the ovule integuments. On maturity it becomes impervious to water hence does not allow water to come out or enter inside. Thus it protects the seed from injury and drying out.
. They are so hard to kill because of their structure. They have a unique cellular structure. They have a hard outer coat surrounding the spore. This makes it hard for disinfectants to penetrate. There is a very thick layer beneath the coat call the cortex. This gives it resistance to heat. There is a germ cell wall under the cortex.Under the germ cell is the inner membrane and it is a permeability barrier against many potentially damaging chemicals.
Spores are very hard and dense, dye is not readily absorbed into the endospore. However, one method of staining is the Schaeffer and Fulton method. The stain is malachite green and the proper method entails preparing a heat fixed smear which is covered by a piece of blotting paper, and flooded with the dye. Wait 15 mins then remove blotting paper and wash. Counterstain with 0.5% Safrinin. Spores appear green.

Their body is covered with a hard exoskeleton.
Since the coat is hard it protects from being eat or like chewed
