the pith is the middle of a tree
The pith is harder because a mahogany tree grows very slowly.
Pith is weaker than the rest of a tree because it comes from the young flexible sapling of an adolescent tree. If the Pith is not removed a builder would have to assume that all the lumber was as weak as the pith, and they would end up using more lumber than necessary to carry the same load.
The center of plant stem that can store food is called the pith. The pith has a spongy texture. The pith in a tree is called the trunk.

It is the photosynthesis receptors that enable the mandarin to reserve resources
The pith of the tree is formed from the procambium, usually during the first year of growth. The heartwood is not a storage area for "impurities". The heartwood is between the pith and the sapwood. It acts as mechanical support for the tree and contains "extractives" (not impurities) that evolve, over eons, to protect the tree from disease, insects, fungi, fire, and other environmental competitors.Pith isn't even considered as wood. It's usually a spongy type of material consisting of parenchymous cells. Heartwood is "dead" and the sapwood, cambium, and inner bark (phloem...HEY, that's my username!) are living tissues (contain cytoplasm)
Yes, monocots do not have pith in their stems.
"Good Sir, I wish to procure a Pith Helmet."
the pith contains ground tissue.
The pith ball will have a negative charge after touching the negatively charged polyethylene strip. This is because electrons are transferred from the strip to the pith ball, leaving the pith ball with a net negative charge.
It is how the tree can let its seeds spread, to make more pine tree's.
The 'charge' in the pith ball is actually caused by too many or too little electrons. When you touch the ball, these billions of electrons would rather move to your nice, moist skin, than stay in the dry pith ball, because your skin is a better conductor than pith is.
