Name___________________ Date ___________________ Section 1 2 3 4 (circle one) Looking Inside Cells 1 Key Concepts Things you need to know... (you may take bullet notes here) 1) What role do the cell wall and the cell membrane play in the cell? _____________________________________________________ _____________________________________________________ _____________________________________________________ _____________________________________________________ 2) What are the functions of cell organelles? _____________________________________________________ _____________________________________________________ _____________________________________________________ _____________________________________________________ 3) How are cells organized in many-celled organisms? _____________________________________________________ _____________________________________________________ _____________________________________________________ _____________________________________________________ 4) How do bacterial cells differ from plant and animal cells? _____________________________________________________ _____________________________________________________ _____________________________________________________ _____________________________________________________ 2 3 Sketch a Cell Follow my lead and copy the picture of a typical eukaryotic cell that I am going to draw on the white board. The labels will match the terms on the vocabulary list for “Looking Inside Cells” on page 5 of this packet. 4 Looking Inside Cells Vocabulary Create flashcards (or another study tool) to help you learn the vocabulary in the list below. If there is a box next to the term, draw a picture of what it looks like. 1) organelle – structures inside a cell that carry out specific functions. 2) cell wall – rigid layer surrounding the membrane that supports and protects plant cells (and some other organisms.) 3) cell membrane – protects cell and allows substances in and out of the cell. 4) nucleus – directs all cell activities. 5) cytoplasm – gel that fills the cell. 6) mitochondria – “powerhouse” changes food into energy. 7) endoplasmic reticulum – “the canals of Venice” carries proteins. 8) ribosome – “jimmies or sprinkles” makes protein. 9) Golgi body – “UPS” packages and ships proteins. 10) chloroplast – makes food with energy from the sun. (photosynthesis) 11) vacuole – “storage tanks” of the cell. Stores food, water, or wastes. 12) lysosome – “recycling centers” break down waste and old cell parts. 5 Looking Inside Cells Bulleted Notes Read Cells and Heredity section 1.2 online (pp. 16 - 24) then complete the following bulleted notes. The red headings have been done for you. Please fill out the blue sub-headings and bullet notes for each paragraph.

Cell parts that the animal cell and plant cells have in common should go in the middle where the ovals overlap. Graphic Organizer: Animal Cell Plant Cell Word Bank: cell membrane cell wall centrosome chloroplast chlorophyll chromatin cytoplasm endoplasmic reticulum (ER) Golgi bodies lysosome mitochondrion nucleus small vacuole large (water) vacuole 13 Cell Organization ORGANS Definition Examples - TISSUES Definition Examples - CELLS Definition - smallest unit of life. Examples - leaf cell, skin cell muscle cell. 14 Sample Eukaryotic Cell 15
