Despite their differences, they share some common structures and functions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>cytoplasm<\/strong> is the jelly-like fluid filling the cell interior. It supports organelles and is the site of crucial biochemical reactions. Both prokaryotic and eukaryotic cells have cytoplasm, though only eukaryotes contain membrane-bound organelles within it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>cell membrane<\/strong>, present in all cells, is a flexible barrier composed of lipids and proteins. It regulates the movement of substances into and out of the cell, helping maintain homeostasis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>mitochondrion<\/strong> is known as the \u201cpowerhouse\u201d of the cell. It generates ATP through cellular respiration. This organelle is found only in <strong>eukaryotic cells<\/strong>, as prokaryotes do not have membrane-bound organelles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>nucleus<\/strong> is another hallmark of eukaryotic cells. It houses the cell&#8217;s genetic material (DNA) and controls cellular activities such as growth and reproduction. Prokaryotic cells, in contrast, have DNA floating freely in the cytoplasm without a membrane-bound nucleus.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Flagella<\/strong> are structures used for locomotion. While both prokaryotes and eukaryotes can have flagella, their composition and structure differ. In prokaryotes, flagella are simpler and rotate like a propeller. In eukaryotes, they are more complex and whip back and forth.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fimbriae<\/strong> are short, hair-like appendages found <strong>only in prokaryotes<\/strong>. Unlike flagella, they are not used for movement but help bacteria attach to surfaces, which is essential for colonization and infection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding these structures helps differentiate between prokaryotic and eukaryotic cells and reveals how form relates to function in cellular biology.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Explain the function of cytoplasm, mitochondrion, cell membrane, flagellum, fimbriae, and nucleus.
