植物哪些部位有叶绿体在6大器官中选
茎 叶 果实和花(花和果实生长阶段有 成熟了就没了)

一般就是在绿色植物细胞中,主要包括叶肉细胞和幼茎皮层细胞。

只要是绿色的部位都有.叶.嫩茎神秘的都有...根没有.地下部分一般都没有.因为不需要...

根茎叶花果实种子,在幼嫩的时候 呈绿色的时候都有。后来成熟后,一般花没有。果实一般少有。根没有。茎要是老的也没有。叶中一般考虑有,除非变黄了

叶绿体一般分布在植物的叶肉细胞、保卫细胞和茎的皮层细胞中(不是表皮,是表皮接下来的第二层开始)
叶和茎表皮细胞缺乏叶绿体。木质部和韧皮部组织通常也缺乏叶绿体
根,球茎,块茎,球茎和根茎普遍缺乏叶绿体,但如果暴露於光照,有一些可以发展叶绿体。
非绿色的花和水果普遍缺乏叶绿体。
就算是红色的叶子也有叶绿体,只是因为花青素过多才呈现红色。
秋天黄色的叶子还是有叶绿...

叶绿体一般分布在植物的叶肉细胞、保卫细胞和茎的皮层细胞中(不是表皮,是表皮接下来的第二层开始)
叶和茎表皮细胞缺乏叶绿体。木质部和韧皮部组织通常也缺乏叶绿体
根,球茎,块茎,球茎和根茎普遍缺乏叶绿体,但如果暴露於光照,有一些可以发展叶绿体。
非绿色的花和水果普遍缺乏叶绿体。
就算是红色的叶子也有叶绿体,只是因为花青素过多才呈现红色。
秋天黄色的叶子还是有叶绿体,只是量较少,所以呈现叶黄素的颜色。但到了快凋零时,叶绿体差不多就被分解掉,其中的Mg也被回收。
缺乏:
分生细胞、输导组织、保护组织(表皮)
寄生的植物,例如印度管道(Monotropa叶草)和菟丝子也缺乏叶绿素。
白化植物也缺乏叶绿素。

Most chloroplasts are in the interior cells in leaves, termed the
misspell, and the cells near the surface of green stems. Many leaf and stem epidermal cells lack chloroplasts. The epidermis is the outermost layer of cells on non-woody plant parts. A pair of guard cells surround each leaf stomata. Guard cells usually have chloroplasts. Cells in xylem and phloem tissue also usually lack chloroplasts. Xylem and phloem provide structural support and internal transport of water, minerals and organic compounds in plant organs.
Most underground plant cells lack chloroplasts because chloroplasts require light for their development. Thus, underground organs such as roots, bulbs,tubers, corms and rhizomes would generally lack chloroplasts. However, underground cells often have other kinds of plastids, such as amyloplasts, which store starch. Underground plant organs may develop some chloroplasts if exposed to light.
Window leaf plants have fleshy leaves that are buried in the soil with just the top showing above ground. The window leaves have many cells in the top center of the leaf that are transparent and let light reach the chloroplast-containing cells on the sides of the leaf. The transparent cells lack chloroplasts.
Parasitic plants, such as Indian pipe (Monotropa uniflora) and dodder, lack chlorophyll so have no chloroplasts. White or yellow tissue in variegated-leaf plants also lack chloroplasts. Albino plants also lack chlorophyll. Many non-green flowers and fruits lack chloroplasts at maturity.

不同的植物要具体考虑。一般植物叶最多,果实有一点,花就看颜色,嫩的茎(绿色的时候),这些部位有。地下的器官没有。

茎:幼嫩茎的皮层细胞中
叶:保卫细胞和叶肉细胞

植物的根部细胞没有叶绿体,因为不需要进行光和作用! 而藻类像衣藻只具叶绿素而没有叶绿体!
