Gymnosperm Leaf (Number 6)

A gymnosperm leaf are group of seed-bearing plants whose ovules are not enclosed in an ovary, but are exposed on the surface of sporophylls or similar structures. Each ovule may contain several eggs, all of which may be fertilized and start to develop in a process known as polyembryony.

Gymnosperm Cone- Male or Female (Number 7)











A gymnosperm cone are the reproductive structures of many gymnosperms arranged in cones. The gymnosperms do not form a distinct monophyletic grouping, but simply include all the seed-bearing plants that are not angiosperms.



C4 Plant {Maize} (Number 8)

A C₄ plant, such as maize, is better adapted than a C₃ plant in an environment with high daytime temperatures, intense sunlight, drought, or nitrogen or CO₂ limitation. Most C₄ plants have a special leaf anatomy (called Kranz anatomy) in which the vascular bundles are surrounded by bundle sheath cells.



C3 Plant {Apple Tree} (Number 9)

C₃ plants, such as an apple tree, is where CO₂ concentration is high, temperature and light intensity are moderate, and ground water is abundant. This is because in hot areas, the stomata are closed to prevent water loss. However, it results in the rise of O₂ level. When this occurs, rubisco reacts with O₂ instead of CO₂, and leads to photorespiration, which in turn, causes wasteful loss of CO₂ in C₃ plants.

C4 Plant {Cactus} (Number 10)

A C₄ plant, such as a cactus, is better adapted than a C₃ plant in an environment with high daytime temperatures, intense sunlight, drought, or nitrogen or CO₂ limitation. Most C₄ plants have a special leaf anatomy (called Kranz anatomy) in which the vascular bundles are surrounded by bundle sheath cells.
