These cone producing plants do not lose their leaves in the winter ____
A
angiosperms
B
gymnosperms
C
flowering
D
spore producing
Explanation: 

Detailed explanation-1: -Gymnosperms include most evergreen species such as pines, spruces and firs. Some gymnosperms, including larch and ginkgo, do lose their leaves in the winter. Gymnosperms are often called “conifers” since many of them produce seeds in cones, as well as “softwoods” since many of them have softer wood.

Detailed explanation-2: -Gymnosperm means as “naked seed". Gymnosperms usually have needles that stay green throughout the year. Examples are pines, cedars, spruces and firs. Some gymnosperms do drop their leaves-ginkgo, dawn redwood, and baldcypress, to name a few.

Detailed explanation-3: -Conifers like the spruce, cedar and pine tree are gymnosperms and have seeds on cones. Most coniferous trees are evergreen and are specially adapted to survive in areas with lots of snow. Many are cone-shaped to help snow slide off them so the branches won’t break.

Detailed explanation-4: -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-5: -At maturity, a gymnosperm embryo has two or more seed leaves, known as cotyledons. Cycads, Ginkgo, and gnetophytes have two cotyledons in the embryo; pine and other conifers may have several (eight is common; some have as many as 18).
