3) A) What process does the growth and reproduction of cells depend on? Cells rely on the process of cell division in order to grow and reproduce. Cell division is the process by which a cell “parent” divides into two or more cells (the cell would first multiply its chromosomes and DNA and then split it all in half to “daughter” create two new cells). B) Name the two types of this process (scientific name and common name) and give an example for each one. The two types of cell division are: Meiosis Sexual reproduction (producing new life/offspring parent cell combines half of chromosomes with – – another parent cell to make a new cell) “daughter” Mitosis Asexual reproduction (producing identical copy for things like healing a wound need the same exact – – cells in order to heal a wound parent cell makes identical copies of itself) – 4) List and describe eight differences between plant and animal cells. Be specific when you describe these differences. Plant Cell Animal Cell Size Larger than animal Smaller than plant cells Rectangular/square Circular/oval in shape Distribution Very tightly packed together More spread out Vacuoles 1-3 very central vacuoles Many smaller vacuoles throughout Organelles No flagellum or Can have flagellum and/or Organelles Has chloroplast (chlorophyll inside contains No chloroplast green pigment; involved in photosynthesis) Organelles Cell membrane AND thick outer Cell Wall Only a cell membrane; no cell wall Shape Change Does not change shape because it has a Easily changes shape because it does thick rigid cell wall not have a thick rigid cell wall 5) Identify each as either a plant or an animal cell, and give four reasons why you classified each one as such. 1. CELL TYPE: ___Plant Cell____ REASONS: 1) Rectangular 2) Large central vacuole 3) Chloroplast 4) Cell member AND cell wall 2. CELL TYPE: ___Animal Cell____ REASONS: 1) Circular/Oval 2) Not closely packed together 3) Only a thin cell membrane 4) many small vacuoles throughout 3. CELL TYPE: _Animal Cell__ REASONS: 1) Circular in shape
