Definition of Gymnosperms and Characteristics of Gymnosperms (Complete)

Definition of Gymnosperms and Characteristics of Gymnosperms (Complete) – Again we will start a new discussion but still in the scope of biology. This time we will discuss about gymnosperms, surely there are still many people who do not know and know the word.

Therefore, about knowledge will provide explanations and reviews about this. So that it can help in understanding and make you understand better. For more details, let's continue the discussion of this article.

Definition of Gymnosperms and their Characteristics (Complete)

Let's discuss the meaning first carefully.

Definition of Gymnosperms

Gymnosperms are derived from the Greek words gymnos which means open and sperm which means seeds. Where gymnosperms are plants whose pollen falls directly on the ovule, where unfertilized seeds are not like the pistil of flower plants. While the meaning of open seeds is not closed in the fruit.

While plants are widely known as conifers or pine which have cones. The term conifer itself comes from the reproductive structure of the plant itself and is also a collection of sporophylls that have a scaly shape.

Characteristics of Gymnosperms

This plant has open seeds and has various characteristics, what are the characteristics of this plant? To be able to more clearly know the characteristics of this plant, let's together continue the next discussion.

1. Have true roots, stems and leaves
2. While the leaves are narrow and stiff
3. The ovules do not get protection from the fruit leaves
4. Bakan grows and is located outside the megasporophyll or ovary
5. Megasprofile in the form of scales to support the ovules which collects in the form of strobilus or conifers and is woody except for cycas.
6. Separate male and female soprofiles
7. Have no true flowers
8. Don't have a flower crown
9. Flowers in the form of strobili that are capable of producing secretions in the form of sap droplets containing male sex cells in male strobili and egg cells in female strobilus
10. The ovules are outside so they can't be protected by the fruit leaves
11. Hesterosporous plants that can produce two types of spores
12. The first spore is in the form of megaspores which then form gametes, and the second spore is in the form of microspores which produce pollen
13. During reproduction, single fertilization occurs

That's what can be explained about Definition of Gymnosperms and Characteristics of Gymnosperms (Complete), where this plant is an open seed plant that has various or many characteristics that this plant has, hopefully it will be useful for those who read it
