How do I use this great invention, microscope? People use microscopes to see Cells • Are the smallest unit of life that carries out all life functions • Contain major structures inside that perform these life functions • Vary in size, but contain many of the same structures 1.1 Animal cell structure All cells have three basic structures in common. cytoplasm nucleus cell membrane cytoplasm nucleus x400 cell membrane Comparing plant and animal cell structure Comparing plant and animal cell structure vacuole nucleus cytoplasm cell membrane (inside barrier) cell wall (outside barrier) Comparing plant and animal cell structure Which structures both plant and animal cells have in common? x100 x400 Comparing Plant and Animal Cells • Plant cells have a cell wall (to give extra support and shape), but animal cells do not. • Plant cells have chloroplasts (that enable plants make their own food), but animal cells do not. Comparing Plant and Animal Cells • Plant cells usually have one or more large vacuole(s) (help provide shape and allow the plant to store water and food for future use), while animal cells have smaller vacuoles,if any are present. Comparing Plant and Animal Cells (write down question and answer) 1) What cell parts are common to both plant and animal cells? 2) What cell parts are only found in plant cells? 3) What cell parts control what enters and leaves the cell? 4) What materials must enter the cell? 5) What materials must leave the cell? 1.Finish Color Code Cells Diagrams Cell Membrane Nucleus Cytoplasm Vacuole Mitochondria Cell wall Chloroplast 2.
