Plants are eukaryotic photosynthetic organisms that have cells with cellulose cell walls. The basic structure of plants includes roots, stems, and leaves, which perform specialized functions such as water and nutrient absorption, support, and photosynthesis. Differentiate plants from other biological kingdoms, highlighting a unique characteristic of plants that distinguishes them from others. Additionally, mention two main subgroups of the Plant Kingdom and a distinctive characteristic of each.

Biocycles are large sets of ecosystems that share specific characteristics related to the nature of the environment in which they live and the life forms that inhabit it. Considering the three biocycles: epinocycle, talassocycle, and limnocycle, which one refers to the set of terrestrial ecosystems?

Protozoans are single-celled eukaryotes that can be found in various aquatic and terrestrial environments, and some are known to cause serious diseases in both humans and animals. In a hypothetical scenario, a group of researchers discovered a new species of protozoan in a contaminated water sample. The researchers also found that this species has the ability to photosynthesize and can be classified as an alga as well. Consider the characteristics of this new species and the information about the diseases caused by protozoans, and answer the following questions: 1) Discuss the morphological and physiological features that allow this new species to be classified as both a protozoan and an alga. 2) Propose a potential mechanism by which this species could contribute to the spread of infectious diseases, considering its dual classification and the characteristics of known disease-causing protozoans. Your answer should integrate knowledge of both biology and environmental science, highlighting the interdisciplinary nature of understanding and addressing issues related to infectious diseases and environmental contamination.
