Its hard
Seed-producing plants have a hard, protective shell that safeguards them from getting damaged.
Its the surface Embryo & endosperm
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.
spores
A mango seed will not germinate if it is coated with pomade. This will prevent the seed from germinating and growing.
No
comfit
Seed that is coated to make it easier to handle/plant
Not much. If my memory serves me correctly (I used to work in the vegetable seed industry), it should be less than 15 grams, assuming the seed is raw and not coated.
It is called a seed coat.
Goes back to Gen.3:15 "...enmity between thy seed and her seed..," i.e., between the children of the devil and the children of God.
A pumpkin might fit that description. One might be the almond,which is a type of peach of which the flesh is discarded.The other could be the coconut.The outercase is removed to reveal the nut(seed) I don't think the fruit is discarded as such. In some cases, the seeds are the fruit and the rind/shell/cover is discarded. An example would be the pomegranate. Coffee. The coffee bean is covered with a sweet flesh when it's harvested. That's washed away and only the seed - the coffee bean - is used.
Its hard

A hard shell around a seed, properly known as 'aril'
A seed is not a hard wood or soft wood. The seed might be of a hardwood or soft wood tree. I think many (not all) eucalypts (gums) are hard wood trees.
