Detailed explanation-1: -Gymnosperms are the seed-producing plants, but unlike angiosperms, they produce seeds without fruits. These plants develop on the surface of scales or leaves, or at the end of stalks forming a cone-like structure.

Detailed explanation-2: -In gymnosperms, a leafy green sporophyte generates cones containing male and female gametophytes; female cones are bigger than male cones and are located higher up in the tree. A male cone contains microsporophylls where male gametophytes ( pollen ) are produced and are later carried by wind to female gametophytes.

Detailed explanation-3: -Gymnosperms are a group of plants that produce seeds that are not contained within either the fruit or the ovary of a plant. The seeds of a gymnosperm are open to the air and are directly fertilized by pollination.
