Cells! What are these? Cell Size Comparison What are the parts of the cell? What are the differences between plants & animals? Plant vs Animal Cells– what’s the diff? Make Observations on what structures and organelles are the same/different & complete the Venn Diagram ►A Cell Membrane thin outer membrane of the cell ► Protects the cell from the external environment ► Controls material going in and out of the cell Cell Wall ► Tough, rigid structure that surrounds the cell membrane ► Provides structural support in Plants ONLY Centrioles ► Paired cylindrical organelles ► Located nucleus near the ► Involved division in cell Chloroplast ► Organelle which traps the energy of the sun to produce glucose using photosynthesis ► Contains chlorophyll (green pigment) ► Found Cells only in Plant Cytoplasm ► A jelly-like substance inside a cell ► Contains everything within the cell (organelles, water, & other materials) Endoplasmic Reticulum ►A network of membrane-covered channels in the cell ► Connected to the nuclear membrane (always near by) ► Transports materials ► Smooth ER= no ribosomes ► Rough ER= ribosomes Golgi Body ► Sorts and packages proteins ► Found near the nucleus Ribosomes ► Small organelle, sometimes attached to Endoplasmic Reticulum, sometimes detached in nucleus ► Make up the nucleolus ► Ribosomes are responsible for making proteins Vacuole** ► Storage membrane organelles ► Can be many in a cell ► Plant cells often have one large central vacuole to store water (small one to store starch) Lysosome** ► Remove harmful & waste materials from cell ► Package up these materials and exit through cell wall Mitochondria ► powerhouse of the cell ► Provide energy by converting glucose ► In both plant & animal cells Nucleus ► The organizing body; controls all activity in the cell ► Contains chromosomes (DNA) which contain the code for all function and features of each cell, each organism Nucleolus ► Free-floating organelle in the centre of nucleus ► Role is to make proteins Plant or Animal?
