Agenda: Quiz Notes: Cell Parts Animal Cell and Plant Cell Pictures Day 24 Agenda: Quiz Notes: Cell Parts Animal Cell and Plant Cell Pictures

Bell Ringer Day 24 For each statement, write the statement, then answer prokaryote, eukaryote, or both Has no nucleus Has a cell membrane Has membrane-bound organelles Plant and animal cells Bacteria cells Can be multi-cellular

Organelle- part of a cell that is specialized for a specific function Cell Parts Organelle- part of a cell that is specialized for a specific function

Surrounding the Cell

Cell Membrane Outer membrane of cell that controls movement in and out of the cell Lipid bi-layer http://library.thinkquest.org/12413/structures.html

Cell Wall Most commonly found in plant cells & bacteria Supports & protects cells http://library.thinkquest.org/12413/structures.html

Inside the Cell

Nucleus Directs cell activities Separated from cytoplasm by nuclear membrane Contains genetic material - DNA

Nucleolus Inside nucleus Where ribosomes are made http://library.thinkquest.org/12413/structures.html

Cytoplasm Gel-like mixture Surrounded by cell membrane

Ribosomes Make proteins from DNA instructions Found on ER& floating throughout the cell http://library.thinkquest.org/12413/structures.html

Endoplasmic Reticulum Smooth ER: lacks ribosomes– makes and transports lipids Rough ER: ribosomes in surface—makes and transports proteins http://library.thinkquest.org/12413/structures.html

Mitochondria Releases energy through cellular respiration– breaking down fats & carbohydrates http://library.thinkquest.org/12413/structures.html

Golgi Bodies Packages proteins Move materials within the cell Move materials out of the cell http://library.thinkquest.org/12413/structures.html

Lysosome Recycles old cell parts and breaks down unwanted material Transports undigested material to cell membrane for removal http://library.thinkquest.org/12413/structures.html

Vacuoles Membrane-bound sacs for storage Contains water solution Central vacuole— helps plants maintain shape http://library.thinkquest.org/12413/structures.html

Chloroplast Usually found in plant cells Contains green chlorophyll Where photosynthesis takes place http://library.thinkquest.org/12413/structures.html

Cytoskeleton Helps cells move and maintain shape and structure Flagella—whiplike structures for movement Cilia—shorter hairlike structures for movement
