This reading is an excellent example of how a seemingly simple plant is composed of a variety of complex categories and systems.

There are 2 major tissues found in plants: 1) meristematic tissues and 2) permanent tissues. Meristematic tissue is the location of a plant where cells are actively dividing and growing while Permanent tissue is the location of a plant where the cells are no longer dividing. Meristematic tissue contains 3 regions of plant growth: 1) apical meristems-plant extension- 2) lateral meristems-plant thickness- and 3) intercalary meristems-plant length.

The plant organ system is composed of 2 categories: 1) • Shoot organ system (non-reproductive and reproductive part of the plant) - used to obtain light for photosynthesis above ground 2)• Root organ system- used to obtain nutrients (water and minerals) underground

The reading discusses the importance and value of plants and photosynthesis to our everyday lives. Although plants are broken down into a plethora of categories, they all behave very similarly (using photosynthesis to obtain nutrients) and share the same basic structure (consist of roots, stems and leaves).

Plants that contain seeds are divided into 2 categories: 1) gymnosperms and 2) angiosperms -Gymnosperm: seeds are not protected -Angiosperm: seeds are protected
