Answer:
about the Trilobites is =Trilobites ( /ˈtraɪləˌbaɪt, ˈtrɪ-, -loʊ-/;[4][5] meaning "three lobes") are a group of extinct marine artiopodan arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years.[6] . and about the algae is =Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.

Stem cells are the primal cells which develop from adult body tissues and embryos. These are present in the adult body through out their life. These are also called tissue specific or somatic stem cells. These are more specialised than embryonic stem cells. These stem cells are found in bone marrow, brain, blood and blood vessels, skeletal muscles, skin and the liver. Differentiation is the process where an unspecialised cell acquire cellular character which allows it to perform specialised functions. During embryonic stage, the cells of embryo make a number of cell fate decision that result in the decreasing capability eventually producing the specialised cells. Stem cells can divide and produce new cells, Hence they have the potential to be transplanted to the patient to treat medical conditions and disease. They are removed form the embryo where they exist as unspecialised stem cells and they will differentiate into any cell type. Specialised cells include many cells like nerve cells, blood cells, ovum cells etc. These specialised cells help in reproduction, energy metabolism, regeneration, information transfer etc.
