Cell structure and function(Eukaryotic cells)Standard 4 Key idea 1 Major understanding 1.2f, 1.2g, 1.2i, and 1.2j Notes: This power point presentation is made by Eunah Kim.
Bell Ringer questionWrite down things inside a cell you already know. Organelles of a cell 1. Plasma membrane: the outer membrane of the cell2. CytoplasmThings inside the cytoplasm: a. Centrioleb. Ribosomec. Mitochondriond. Vacuole e. Endoplasmic reticulum f. Golgi complex g Lysosome h. Chloroplast (only for plants)3. Nucleus Things inside the nucleus: DNA
Activity Label each organelle and write its function on the cell diagram booklet. Special organellesMitochondria: found in all eukaryotic cells (both in plant cells and animal cells)Function: extraction of energy from nutrients through cellular respiration (chemical respiration). Power house of a cell.

http://www.ftmguide.org/hormonebasics.htmlCellular communication contReceptor molecules recognize specific hormones or neurotransmitters and deliver the information to the interior of the cell.Two types of agents of cellular communication:Hormones i.e.) growth hormoneNeurotransmitters i.e.) acetylcholine Cellular communication contHormones i.e.) growth hormoneChemicals that are secreted by endocrine glands and delivered through the blood to affect target cells.2) Neurotransmitters i.e.) acetylcholine Chemicals that are secreted from one neuron cell and carry the impulse to the next neuron.
