Thursday 1/12 Day 2 2- Fill out your Agenda. 1. Please have these Science Starters Sheet Agenda 1. Please have these items on your desk. 2- Fill out your Agenda. Wednesday – Hamilton High School Field Trip Thursday 1. What was the CTE that you are most interested in taking in High School? 2. What do you know about cells?
Cell Parts & their Function Cell Anatomy Cell Parts & their Function
It is the basic unit of living things. What is a Cell? A cell is the smallest unit that is capable of performing life functions. It is the basic unit of living things.
Cell Theory All living things are made up of cells. Cells are the smallest working units of all living things. All cells come from preexisting cells through cell division.
Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell Nerve Cell
Cell Organelles Cell Parts are referred to as organelles.
Cell Wall Most commonly found in plant cells & bacteria Supports & protects cells Cell Wall
Cell Membrane protective layer around all cells allows food and oxygen into the cell and waste products out of the cell. Cell Wall Cell Membrane
Cytoplasm Gel-like material Surrounded by cell membrane Cell Wall
Nucleus contains instructions for everything cell does; includes DNA Cell Wall Cell Membrane Cytoplasm Nucleus
Ribosome Each cell contains thousands Make proteins which repairs cells (Think of it like a battery plant!) Found on ER & floating throughout the cell Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome
Endoplasmic Reticulum (ER for Short) Moves materials around in cell (Like a highway) Smooth type: lacks ribosomes Rough type : ribosomes embedded in surface Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER
Mitochondrion releases energy from food (Energy Plant) Controls level of water and other materials in cell Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER Mitochondrion
Chloroplasts Found only in plant cells. Contains green chlorophyll Where photosynthesis takes place Helps plant cells make food. Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER Mitochondrion Chloroplasts
Vacuole membrane-bound temporary storage spaces Contains water solution Help plants maintain shape Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER Mitochondrion Chloroplasts Vacuoles
Golgi Body Protein 'packaging plant' Move materials within the cell Move materials out of the cell Cell Wall Cell Membrane Cytoplasm Nucleus Ribosome ER Mitochondrion Chloroplasts Vacuoles Golgi Body
