Science Fair Project

How do we grow? Does our cells get larger? Cell Division

Cell Cycle Interphase Prophase Cytokinesis Metaphase Telophase DNA Replicate Prophase Chromosomes pair up Cytokinesis Two cell are creates Metaphase line up in middle Telophase Chromosomes move far away Anaphase Chromosomes pull apart

Cell Cycle Interphase Cytokinesis Mitosis Two cell are creates DNA Replicate Cytokinesis Two cell are creates Mitosis Nucleus divide into two A copy of DNA is distributed to each Nucleus

Cell Cycle ? ? ? ? ? ? Interphase Prophase Cytokinesis Metaphase Telophase Anaphase ? ?

Interphase ob Stage 1: Interphase: Period before cell division occurs. Cell is doing its J___ while growing (doubles in size) Replicates (make a copy) its DNA ob

Mitosis : Prophase air up Prophase: Identical Chromatids p______. They are held together by a centromere air up

Mitosis : Metaphase iddle Metaphase: Chromosomes line up in the m______ iddle

Mitosis : Anaphase part Anaphase: The centromeres split and the chromosomes are pulled a______ part

Mitosis: Telophase ar Telophase: Each set of chromosomes are F___ away and a nucleus forms around them ar

Cytokinesis oves Cytokinesis The cell membrane m______ inwards then pinches in two. This form 2 identical cells oves

DNA – Deoxyribonucleic Acid Nitrogen Based Molecules (4 Letters of DNA Alphabet) Adenine – Thymine Guanine - Cytosine

Reflection Prompt: Draw the Elodea Plant Cell through the microscope and write one question that you have about the observation.
