First of all, lets define a "Weed". A Weed is ANY plant that is in an undesirable location, so a Rose in the middle of your lawn could be a weed, or grass in your Rose Garden could be a weed. You probably picked a Dandelion and noticed that the stem was hollow. Dandelion & Golden Rod are 2 examples of plants with hollow stems. These are exceptions, not typical.
Some common lawn & garden weeds are; Dandelion, Chicory, Clover, Oxalis (which looks like Clover & tastes like sour apples), Plantain (which looks like a cross between Dandelion & Chicory), Mouse-Eared Chickweed, Fennel & Violets. I'm using W. PA as an example.
Hope this helps,

An angelica is a tall plant, with hollow stems, of the genus Angelica, or the candied stems of the plant used to decorate cookies.
An angelique is a tall plant with hollow stems of the genus Angelica.
(Arthrophytes ) Plant stems are filled with hollow tubes that run parallel to the stem. These tubes use pressure to transport water to areas of the plant that need it.
Mud,grass,weed stems,
There are basically two different types of stems. The fleshy solid ones are called woody stems and the hollow stems that look like straws. The solid ones are a bit more efficient in drawing water because the capillary system is continuous. The hollow ones draw water without the benefit of the capillary mesh that the woody stem does.
Leaves and stems will break down and be beneficial to the compost, but woody stems might take a long time to break down. You should not put weeds in compost, especially if they have seeds on them because it can create a weed problem in your garden.
