"Gymnosperm" is an informal term for any plant of the extant groups Coniferophyta, (conifers) Cycadophyta, (cycads) Ginkgophyta (1 species gingko biloba), and Gnetophyta as opposed to the angiosperms or flowering plants. Gymnosperms reproduce by means of seeds. Unfertilised seeds are called "ovules" With the first cell division it is called a "zygote" and thereafter an "embryo". The male gene carrier is called pollen. (For more about pollen - ask. The seeds of gymnosperms are in direct contact with the environment (can be covered with a scale as in "cones"). The ovules of angiosperms, by contrast, are encased in an ovary.
A worm's body typically consists of several segments called metamerism, which contain various organs such as the digestive system and reproductive structures. The digestive system, consisting of the mouth, pharynx, esophagus, crop, gizzard, and intestine, plays a crucial role in breaking down organic matter for nutrition. Reproductive structures, such as testes or ovaries, are also present in their body.
Biologically, penises are structures that contain reproductive organs necessary for sperm delivery during sexual intercourse. Females have different reproductive structures, such as the vagina and clitoris, which support the female reproductive system. These anatomical differences between males and females are a result of their distinct roles in reproduction.

The urinary system and the reproductive system make up the urogenital system in a fetal pig. The urinary system includes the kidneys, ureters, bladder, and urethra, while the reproductive system includes the ovaries or testes and associated structures.
A bird's reproductive opening is called a cloaca. It is used for both reproduction and waste elimination.
The male reproductive structures of a pea plant are called the stamen
The female reproductive structures in a flower is called the pistil.
stamen and pistil.
No, fronds are not the sexual reproductive structure of ferns. Fronds are the leafy structures of ferns that help in photosynthesis and reproduction occurs through specialized structures called spores produced on the underside of the fronds in structures called sori.
The gametophytes of gymnosperms live inside reproductive structures called cones. Gametophyte is the immediate result of fertilization in mosses.
Reproductive structures of spore-bearing plant is called sporangia.
Reproductive structure of fungi, forms new fungus bodies
Carpels, consisting of ovary, stigma and style
Carpels, consisting of ovary, stigma and style
Reproductive structures of spore-bearing plant is called sporangia.
All gymnosperms have cones as reproductive structures.
The kind of growth that involves roots and shoots but not reproductive structures is called vegetative reproduction. Some biologists call it asexual reproduction.
