Premium Life Organism Biology
Protists are an eclectic group of eukaryotic organisms. Imagine the creatures belonging to the other eukaryotic kingdoms telling protists‚ “You can’t sit at our table‚” so the protists start their own club. Although protists don’t belong to the plant‚ animal‚ or fungi club‚ they still share many characteristics with other eukaryotic life forms. What makes a protists a protists is the fact that it cannot be placed into any of the other kingdoms physically or genetically. For instance‚ the plant-like

(Simon‚ Reece‚ & Dickey‚ 2010). The diploid cells split up to form four haploids (form of cell division that most eukaryotic cells undergo)‚ however‚ only half of the chromosomes are the parent cells and occurs in all organisms that have sex cells (Simon‚ Reece‚ & Dickey‚ 2010). Ex: humans‚ animals‚ most fungi‚ and plants. Mitosis is the form of cell division that most eukaryotic cells undergo. In humans‚ all somatic (non-sex) cells use mitosis to divide. This does occur in all organisms and

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions

p.92\ a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.
