Thekey difference卵巢和卵子之间卵巢是女性生殖结构的一部分,该结构发展成开花植物while the ovule is a structure that develops into a seed of seed plants.
花是开花植物的生殖结构。有些花很完美,而有些则是不完美的花朵。完美的花朵包含男性和女性生殖部位androecium and gynoeciumrespectively. Gynoecium has three main components namelystigma, style and ovary. Accordingly, the ovary is the structure that contains ovules. We can find it at the base of the gynoecium. Thus, ovules are the structures that bear female reproductive cells or the egg cells. Ovary surrounds the ovules in flower. One ovary may contain many ovules but, one ovule often contains one egg cell (female gamete). After fertilization, ovary and ovule develop into different structures of a fruit.

什么是卵巢?
卵巢是含有胚珠的植物生殖结构的三个主要部分之一。我们可以在腹膜内的底部或附着在插座上的雌蕊的底部找到它。大多数卵巢是烧瓶形的,而有些则是圆形的。授粉后,花粉管通过卵巢壁朝着雌性配子体生长。因此,卵巢履行了植物中的两个主要功能。它含有胚珠,还促进了花粉管向雌性配子体的生长。一旦施肥过程结束,卵巢就会在开花植物中发展成果实。
Based on the arrangement of the ovary with respective to the insertion point of the flower, there are three main types of ovaries. They are the superior ovary, half-inferior ovary, and inferior ovary.
What is an Ovule?
胚珠是包含植物生殖细胞的结构。我们可以在卵巢中找到它。一个卵巢可能包含很少的胚珠。但是每个胚珠都包含一个鸡蛋细胞。例如,您可以注意到西瓜内部的几十个种子,而桃子的果实中只有一个种子。它的意思是;西瓜卵巢内部有许多胚珠,而桃子卵巢内只有一个卵形。
In flowering plants, the ovule eventually converts into female gametophyte or the embryo sac that contains eight cells including an egg cell during the sexual reproduction. After a successful fertilization process, ovule develops into a seed of the fruit.
What are the Similarities Between Ovary and Ovule?
- Ovary and ovule are two structures that involve with sexual reproduction of plants.
- Also, both structures develop into parts of fruit after fertilization.
- 此外,两者都是母体植物的一部分。
What is the Difference Between Ovary and Ovule?
The ovary is the round base of the pistil that contains the ovules. On the other hand, ovules are the structures that contain female reproductive cells or the female gametes. Therefore, this is the key difference between ovary and ovule.
Based on what they become after fertilization, we can find a difference between ovary and ovule. The ovary turns into a fruit while the ovules become its seeds. The below infographic on difference between ovary and ovule presents the comparison in tabular form.
概括– Ovary vs Ovule
Ovary and ovule are two components of a flower of plants. The ovary is a part of the pistil that contains the ovules. We can find it at the round base of the pistil. On the other hand, ovule is the structure that contains a female reproductive cell or the egg cell. Therefore, this is the key difference between ovary and ovule. After successful fertilization, ovary develops into a fruit while ovule develops into a seed of the fruit. Thus, this is another difference between ovary and ovule.
