Thekey differencebetween actinomorphic and zygomorphic flower is thatactinomorphic flower is a flower that is radially symmetrical and can be divided into two equal parts along any diameter while zygomorphic flower is a flower that is bilaterally symmetrical and can be bisected into two equal parts only in one plane.
Floral symmetry explains whether the flower can be bisected into mirror images. Some flowers are radially symmetrical while some flowers are bilaterally symmetrical. However, some flowers are asymmetrical. Flowers with radial symmetry can be bisected into identical halves along any diameter. Those flowers are called actinomorphic flowers. In contrast, flowers with bilateral symmetry can be bisected into two identical halves in only one plane. Those flowers are called zygomorphic flowers.

什么是阳光的花?
An actinomorphic flower is a flower that can be divided into three or more identical sectors along any diameter or any vertical plane. Many flowers are actinomorphic. They are radially symmetrical and star-shaped regular flowers. Floral organs of actinomorphic flowers are equal in size. Hence, they are regular flowers.
When bisected in any diameter, actinomorphic flowers give two identical halves.Romulea roseaflowers are actinomorphic flowers. Furthermore, lily (Lilium, Liliaceae) and buttercup (Ranunculus, Ranunculaceae) flowers are also actinomorphic flowers. Actinomorphic flowers are a basal character of被子植物.
What is a Zygomorphic Flower?
A zygomorphic flower is a flower that can be divided into two mirror images by only a single plane. Similar halves can be obtained from only one vertical plane. These flowers are bilaterally symmetrical. Zygomorphic flowers have floral parts which are unequal in size. The corolla especially has unequal size花瓣, so they are irregular flowers.
剑兰flower (Iridaceae) is one example of a zygomorphic flower. Moreover, orchids and flowers of most members of the Lamiales are zygomorphic flowers. Zygomorphic flowers are a derived character of angiosperms. There are three types of zygomorphic flowers as typically zygomorphic, transversely zygomorphic and obliquely zygomorphic.
What are the Similarities Between Actinomorphic and Zygomorphic Flower?
- Actinomorphic and zygomorphic flowers are two types of flowers based on their symmetry.
- 两种类型的花在分配时都会给出镜像。
放线态和伴形花之间有什么区别?
当沿任何直径分配时,放线肌花会产生两个相似的一半。相比之下,合格花朵仅在一个平面中分配时会产生两个镜像。因此,这是放线肌和Zygomorphic花之间的关键区别。放线肌的花朵具有相等大小的花朵零件,而Zygomorphicplophic花的大小不等花器。此外,放阳光的花是普通的花朵,而Zygomorphicplophic花是不规则的花朵。玫瑰,百合花和毛cup是阳性花朵的例子,而兰花是同变花朵的一个例子。

概括– Actinomorphic vs Zygomorphic Flower
Actinomorphic flower is a radially symmetrical flower. It produces mirror images when bisected along any vertical plane. In contrast, zygomorphic flower is a bilaterally symmetrical flower. It produces two mirror images only from one vertical plane. Thus, this is the key difference between actinomorphic and zygomorphic flower. Zygomorphic flower has unequal size flower parts while actinomorphic flower has equal size flower parts, especially petals. Therefore, actinomorphic flowers are regular flowers, while zygomorphic flowers are irregular flowers.
