The plastids developed as the so called proplastids.
质体转变为所谓的原质体。
Usually, plants perform photosynthesis by way of tiny organelles called plastids.
通常，植物是靠一种叫做叶绿体的纤小细胞器完成光合作用的。
The slugs digest most of the algae, but those plastids remain whole and undigested.
海藻的大部分被这种海蛤蝓消化，但是叶绿体保持完整不被消化。
Regulation of foreign gene expression in plastids is influenced by various factors.
外源基因在质体中的表达调控受多种因素影响。
The SEs were rich in mitochondria, P type plastids, and some SEs had nacreous wall.
筛分子内有较丰富的线粒体、P型质体，有些筛分子有珠光壁。
Polyphenol oxidase (PPO) is a ubiquitous copper metalloprotein in the plastids of many plant species, fungi and insects.
多酚氧化酶是一类普遍存在于植物、真菌、昆虫的质体中，由核基因编码能与铜相结合的金属蛋白酶。
Once the sea slug has eaten enough algae, and gained enough plastids, it can live off just sunlight for up to nine months.
一旦海蛤蝓吃饱了海藻，储备够了叶绿体，它能仅仅靠阳光就能生活最多9个月。
In addition, plant cells contain plastids that utilize light energy to manufacture carbohydrates in the process of photosynthesis.

Caroteinoids, which have a range of diverse biological functions and actions, are orange, yellow, or red pigments present in all plastids.
类胡萝卜素是一类橘黄、黄色或红色的色素，存在于质体中，具有许多不同的生物功能和生物活性。
Plastids are essential organelles of plant cells and it is believed that plastids have arisen from an endosymbiotic event between a protoeukaryote and a photosynthetic prokaryote.
叶绿体是植物细胞内的一种重要细胞器，它起源于早期具有光合能力的原核生物与真核生物的内共生事件。
