The plant kingdom contains mostly photosynthetic organisms; a few parasitic forms have lost the ability to photosynthesize. The process of photosynthesis uses chlorophyll, which is located in organelles called chloroplasts.

- Figure \(\PageIndex{4}\): This apple seedling is an example of a plant in which the apical meristem gives rise to new shoots and root growth.
- A representation of the different types of plants found today. Many produce flowers, plants called Angiosperms, which will give rise to fruits such as berries and nuts.
- The agave plant. During sexual reproduction, the branches of the stalk are covered with masses of yellow flowers. After this time, the “mother” plant will die with the stalk falling and the offspring being dispersed.

- The fern life cycle. The adult fern we see growing is the sporophyte at the top of the image, whereas the gametophyte is in the soil and out of view.
Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. The plant kingdom contains mostly photosynthetic organisms; a few parasitic forms have lost the ability to photosynthesize. The process of photosynthesis uses chlorophyll, which is located in organelles called chloroplasts.
Division Thallophyta. These are the lowermost plants of the plant kingdom, without a well-differentiated body design. This means that the plant body is not differentiated as roots, stem, and leaves. They are commonly called algae, are permanently aquatic. Examples include Spirogyra, Chara, and Ulothrix. Download Plant Kingdom Cheat Sheet PDF.
