하월시아 푸밀라 잎장 확대사진..

하월시아 푸밀라 잎장 표면의 확대사진을 인터넷 검색에서 발견하여 기록사진 남겨본다.

창의 표면이 오돌도돌해서 벌레로부터 보호하고 약간 낮는 분화구 형태의 기공으로 호흡하는 것으로 보인다.

Caption: Haworthia leaf. Coloured scanning electron micrograph (SEM) of a leaf of a Haworthia pumila plant.

              A section has been cut away to reveal the underlying cells.

             The leaf is covered with a layer of epicuticular wax (blue) which protects it from evaporation and plant-eating animals.

             The crater-like structures on the leaf's surface are breathing pores or stomata.

             These regulate the exchange of gases between the leaf and the atmosphere.

             Within the cells are chloroplasts (green balls), the sites of photosynthesis.

             Haworthia is a succulent plant which is native to desert regions.

             It is often used a household plant. Magnification: x200 at 6x7cm size. x300 at 4x5"

             Haworthia is a succulent plant which is native to desert regions.

             It is now used as a household plant because of its rosette leaves. Magnification: x40 at 6x7cm size. x62 at 4x5"
