Mitosis History of Understanding Cancer Rudolf Virchow 18211902 First to recognize leukemia in mid1800s believing that diseased tissue was caused by a breakdown within the cell and not from an invasion of foreign organisms. Kingdom Protista. A. Sometimes not considered a true kingdom because the organisms vary tremendously from one to another. The only universal characteristic among the group is that they are all eukaryotic.. TSW – Recognize that the presence of a nucleus determines whether a cell is prokaryotic or eukaryotic. 6.12B.

Eukaryotes. Chapter 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. . Copyright © 2002 Pearson Education, Inc., publishing as Benjamin Cummings. Eukaryotic Cell. 3. Eu. = True. Karyon. = Nucleus. B- The Eukaryotic Cell. Animal Cell. Plant Cell. Compare Animal and Plant cell. Chapter 4: Animal Growth and Heredity. Vocabulary. Life cycle- the stages that a living thing passes through as it grows and changes.. Mitosis- the process by which most cells divide.. Chromosome- A threadlike structure in the nucleus, made up of DNA.. Eukaryotic Cell. 3. Eu. = True. Karyon. = Nucleus. B- The Eukaryotic Cell. Animal Cell. Plant Cell. Compare Animal and Plant cell. What are the functions of cell organelles . ?. Copyright © 2002 Pearson Education, Inc., publishing as Benjamin Cummings. Chapter 10. Limits to Cell Size. Cells grow as the organism grows.. However cells only grow to a certain extent then divide. Why?. . - The larger the cell the more demands on its . dna. . - a large cell has more trouble moving food in and waste out. Phases of the cell cycle. Interphase. Mitotic Phase. Interphase. G1. - a cell grows and develops. S. - a cell continues to grow but copies its DNA. G2. - still growing but begins to store energy and get ready to divide. 1 x All cells are formed by division of pre - existing cells x Each new individual begins its life as a new single cell commonly the fertilized egg or zygote x A large number of cells are being t : Practice using the compound light microscope.
