The Nucleolus

Nucleus: Nucleolus Iris: Pupil
 * The most prominent structure in the nucleus is the nucleolus. || [[image:https://lh6.googleusercontent.com/eLXL6DZNoS2u2h116Ux8d64QdGwd2JoxC12UDWPfIcXaiCcgZXgv_-bnUw9OmlAZTX2m70UXR1g2IJrwvWlCWOqekLynR3MZyfFL2I6BqGq1UrcmVylgE3AxvMtX8I82J0b0LPZQ width="298" height="179"]] ||

In Latin it means "a little nut". ||
 * Fontana used a compound microscope to discover the circular organelle. || [[image:https://lh6.googleusercontent.com/UV8WmqEieoL-A5J_KR1qMz4exD-P7N26LZTiOGrKOn1ZVzLWAQeeYE77M9--G1C966eOhiDXyGHVIgdbbmzjfwu6wCBsds9GuyKRTlhXG7XEdYgEjgrxGANlf9FyyWcRe-i1-P-N width="165" height="165"]] ||
 * The nucleolus produces ribosomes, which move out of the nucleus and take positions on the rough endoplasmic reticulum where they are a critical part in protein synthesis. || [[image:https://lh3.googleusercontent.com/XtdmaJiY9aupuuMDe1-4oWLXKa3kry7z2VJKbR-qucvlGqvGfIZxh4jP9FFavmXqDKHddSVt9EBMY_O8xjHK1cA-MpK_fIFKnP1Ixw1_BSppHDDurvwEwZYdL83qCEHvt6g74BvF width="215" height="203"]] ||

 * The Nucleolus is only found in eukaryotic cells. Eukaryotic cells contain a nucleolus because, unlike prokaryotic cells, they contain a nucleus. || [[image:https://lh4.googleusercontent.com/bGKHCdEegZQyvPymLTAziMbdRGohGsSv6oKyU0PXRH1pUWI555iqoeF1PTto6W_aFwM9YMrUqij_4bRKdCXCvOx9N6DggHeLG4mDR79_zJ7RUbzdVn6-Lgpz8UEzwArIfHBy5RYg width="147" height="135"]][[image:https://lh4.googleusercontent.com/I6V8a4a0a_54C62ynlcJAJ1P0MmvpHRlhREsbWKF0xeeicQmg_gWcqwWwEoi9Sme1PckRDkKBMbxJGWxngIjFii0Xl6QVEY5LzkMSrBNLiCc3lG8C5J69C5DwRJQk9lREnHNytaw width="232" height="197"]] ||

 * Every eukaryotic cell contains and needs at least one nucleolus to produce ribosomes for protein that aid in in processes such as cell repair. || [[image:https://lh4.googleusercontent.com/2qPqtVK1oxnKljejfI8Kjh38-qculjNR76n3zhttd73BIiF85yLfiZMXHVfqBBEdagsB1-X2U3Pix6sgS30ShM-RBViDIQZQMaJvODPCGcbD96QgHPY6aVbE_Mt6Rm_O3m0Z2HOj width="298" height="227"]] ||

 * The nucleolus does not contain a lipid membrane, meaning it is one of the few non-membrane bound organelles in the cell. In addition, the molecular makeup contains at least two ultrastructural components. || [[image:https://lh4.googleusercontent.com/Hqz1YDJmzEvE0lv8PhIgfJtqaQZssMLYU7jdrPP3MWzQW7KP1eRmnyHRXge9OLyHT9EVp1N6UxdLrNbY2bhvmKkiixCgVK81WD7DFLiSoAqF78DUCMGxmusKWxE5qPDKuX4pxAv9 width="216" height="220"]] ||

 * An analogy ⇒

Explanation ⇒ A nucleolus takes up about 25% of the nucleus’s volume. In addition, an iris takes up about 25% of the pupil’s volume. || ||
