Gymnosperms
• Their flowers are not particularly attractive and they almost always
form structures called cones, often with separate genders.
• Instead of producing fruit, the female cones mature into developed
cones which contain seeds.
• Some examples of gymnosperms are pine trees, firs and junipers.
