英文释义

名词 n.
  1. A rigid, non-living structural layer located outside the cell membrane in certain cells, such as those of plants, fungi, bacteria, and some algae, providing support, shape, and protection.
    — The name of Chlamydomonas is applied to certain microscopic green bodies, each of which consists of a protoplasmic central substance invested by a structureless sac. The latter contains cellulose, as in ordinary plants; and the chlorophyll which gives the green colour enables the Chlamydomonas to decompose carbonic acid and fix carbon, as they do. Two long cilia protrude through the cell-wall, and effect the rapid locomotion of this "monad," which, in all respects except its mobility, is characteristically a plant.
