Gaia Theory and All Life is Connected

The concepts of an interconnected earth are intriguing and measurable. As a botanist and microbiologist I have studied symbiotic relations that range from parasitic to symbiotic. Many indigenous people have understood these concepts longer than modern scientists. The Lakota Sioux state: “Mitakuye Oyasin,”which means, “To all of my relations.” It is a prayer of oneness and harmony with all forms of life: people, animals, birds, plants, insects, and even rocks. It is a reminder that we all share a common kinship within the hoop of life. Our bodies are composites of bacteria, and within our cells are remnants of ancient bacterial cells that are now mitochondria. Dr. Lynn Marguelis a famous botanist, and suppoter of James Lovelock Theory of Gaia states: "The only individuals on the planet are bacteria."

Mitosis, Onions and Tapeworms

Chapter Nine: The Cell Cycle

This week in Biology we have been studying Mitosis. We have observed prepared slides of the root tips of Allium cepa (onion), and next week slides of Ascarcis lumbricoides and Fish (species unknown). We have also been estimating the time that a cell spends in each phase of the cell cycle. Counting the total cells in a field of view, we determined the total number of cells, and then tallied the number of cells in each phase. With this data we are calculating the what percentage each stage is of the total: Interphase, prophase, metaphase, anaphase and telophase.

The above photomicrograph was taken by an inquisitive student.


This Weeks Projects:

(1)Recreating diagrams of the cell cycle.

(2)Vocabulary Fold-ables for 9.1. Including word, definition and symbol.

(3)Reading Guide 9.1-9.2

(4)Final Abstract and Graph for Rates of Diffusion & Surface Area:Volume using Gelatin Cells.

Daily Syllabus: February 9-10, 2012
