33. Using two or three well-developed paragraphs, write the names of the six kingdoms of organisms. Identify several characteristics of each kingdom.

-Most organisms are classified into six kingdoms, which are: Archaebacteria, Eubacteria, Fungi, Protists, Plants, and Animals. Bacteria has two main types: Archaebacteria and Eubacteria. Archaebacteria are single-celled organisms that lack a nucleus and live in extreme environments. Eubacteria are also single-celled and lack a nucleus, but they are much more common compared to archaebacteria. It is a fact that a number of bacteria are very important to humans and the environment. Bacteria are nature’s recyclers and can produce desirable materials and degrade wastes. Even some of the foods we eat today are processed by specific kinds of bacteria such as pickles and cheese.
Fungi have many unique features such as that they do not have chlorophyll to carry out photosynthesis and make their own food. They obtain nutrients by breaking down organic matter in their surrounding environment. Fungi are made up of large slender filaments, unlike plants. Like bacteria, fungi are also very beneficial and are used commercially. An example of this is yeast, which is used in baking, brewing, and making wine.
Protists are all simple organisms and lack highly specialized tissues. Protists are subdivided into several groups based on their characteristics. These include animal-like protozoa, plant-like protozoa, and fungus-like protozoa.
Plants are able to photosynthesize since they have chlorophyll, while converting sunlight energy to chemical energy (food). They can be categorized into three groups: Lower Plants, Gymnosperms, and Angiosperms. Lower plants have no vascular system; examples include ferns and mosses. Gymnosperms are mostly plants and trees that have a vascular system; for example a pine tree. Angiosperms are flowering plants that produce seeds in fruit, such as apple trees and tomato plants.
Animals mostly share the same common features. They are heterotrophic, able to move, can reproduce, exhibit cell organization, and lack cell walls. Two groups are Invertebrates and Vertebrates. Invertebrates are animals that lack a backbone. Vertebrates are animals that have a backbone.


Please let me know what I need to fix up. Thank you very much.
