Parenchyma cells are the most common ground tissue cell type in a plant.

薄壁细胞是植物中最常见的基质组织细胞类型。

Each leaf parenchyma cell can hold hundreds of chloroplasts — that's where all the photosynthesis happens and what gives leaves their signature green color.

每个薄壁细胞可以容纳数百个叶绿体——这是光合作用发生的地方，也是树叶标志性的绿色的来源。

The rest of the stem is filled with ground tissue — those big, juicy parenchyma cells, which help keep the plant upright and store water and nutrients.

茎的其余部分充满了基本组织——那些大而多汁的薄壁细胞，它们有助于保持植物直立并储存水分和营养。
