Algal Cell Walls

Famous quotes containing the words cell and/or walls:

    A cell for prayer, a hall for joy,—
    They treated nature as they would.
    Ralph Waldo Emerson (1803–1882)

    As I sat before the fire on my fir-twig seat, without walls above or around me, I remembered how far on every hand that wilderness stretched, before you came to cleared or cultivated fields, and wondered if any bear or moose was watching the light of my fire; for Nature looked sternly upon me on account of the murder of the moose.
    Henry David Thoreau (1817–1862)
