Prokaryotic chromosome contains mostly DNA and some associated proteins Asexual reproduction requires a single parent; offspring are genetically identical to parent. EUKARYOTES Meiosis and Mitosis MEIOSIS Meiosis is essential for sexual reproduction and therefore occurs in all eukaryotes MITOSIS process in which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two daughter nuclei. It is generally followed immediately by cytokinesis

INTRODUCTION INTO SEEDS AND FLOWERS REVIEW+MORE The cycle of life for a plant starts off as a seed. The seed goes through mitosis and turns into a nature plant‚ which sometimes may produce flowers and fruits. Fruits are where the new seeds can be found‚ continuing the life cycle. A monocot seed with 2 genetic codes (2N) would grow by mitosis. The growth by mitosis would lead to the growth of the apical tips. The meristem cells (stem cells) keep dividing. Then the zone of elongation‚ the plant

Is Interphase part of mitosis? Explain your answer. * Interphase is NOT a part of mitosis because it’s basically just a preparation for mitosis and not actually mitosis. Mitosis is when the diploids are dividing and in interphase this doesn’t happen. 44. Draw Prophase‚ Metaphase‚ Anaphase‚ and Telophase/Cytokinesis and explain what happens during each stage [BACK OF PAPER] 45. Compare and contrast mitosis and meiosis * Mitosis: cell divides only once and the result
