Detailed explanation-1: -Conifers are seed plants, and like most other seed plant groups they have wood, megaphyllous leaves, and of course seeds. These seeds are typically produced in woody cones, though the cones of some conifers are reduced to such a degree that they are no longer recognizable as such.

Detailed explanation-2: -Conifers have two types of cones: pollen cones and seed cones. Depending on the tree species, you may find both types of cones on the same tree or on different trees. When seed and pollen cones are found on different trees, the species is called dioecious. Female cones have scales under which the ovules are found.

Detailed explanation-3: -Virtually all conifers produce cones though the size, shape, colour and texture vary greatly. The Coulter Pine produces cones up to 50cm long and weighing up to 5kg!

Detailed explanation-4: -Seeds are found inside the cone on the upper surfaces of the cone scales. Open cones have dropped their seed; so collect closed cones only, preferably by picking them from trees.

Detailed explanation-5: -The word “conifers” means “bearing cones.” Conifers are plants that use cones to house their seeds. Conifers are woody plants and most of them are trees such as pine trees, firs, cypresses, junipers, cedars, and redwoods. Conifers reproduce using their cones.
