| For example, the tiny air sacs in lungs expand more than seven times when you inhale. |
| Each anther cone was gently agitated to release the pollen sacs into the dye solution. |
| Gametophytic apomicts differ from sexually reproducing plants in that they produce unreduced embryo sacs. |
| The only reason why they are able to stay afloat is their buoyant sacs near their throats. |
| If chemicals are splashed into the eye, the eye and the conjunctival sacs should be washed out immediately with copious amounts of water. |
