ЧТО ОЗНАЧАЕТ СЛОВО LEUCOPLAST
лейкопласты
Лейкопласты являются категорией пластиды и как таковые являются органеллами, обнаруженными в растительных клетках. Они не пигментированы, в отличие от других пластид, таких как хлоропласт. Отсутствие пигментов, лейкопласты не зеленые. Они бесцветны, поэтому они предсказуемо расположены в корнях и не фотосинтетических тканях растений. Они могут стать специализированными для объемного хранения крахмала, липида или белка и затем известны как амилопласты, элаопласты или протеинопласты соответственно. Однако во многих типах клеток лейкопласты не обладают большой функцией хранения и присутствуют для обеспечения широкого спектра важных биосинтетических функций, включая синтез жирных кислот, многих аминокислот и соединений тетрапиррола, таких как гем. В общем, лейкопласты намного меньше хлоропластов и имеют переменную морфологию, часто описываемую как амебоид. В эпидермальных клетках корней, гипокотилей и лепестков наблюдаются обширные сети связок, связывающих лейкопласты, и в каллусных и суспензионных клетках культуры табака.
