7.2 Cell Structure

• Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells

• Organelles “little organs”

Page 2: 7.2 Cell Structure Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells Organelles “little organs”

Organelles

• Nucleus = Holds genetic information – found in all eukaryotic cells – contains chromatin (DNA), nucleolus, nuclear envelope

Page 3: 7.2 Cell Structure Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells Organelles “little organs”

More Organelles

• Vacuoles = store materials (water in plants) – found in eukaryotic cells

• Vesicles = store and move materials between organelles and the cell surface – found in eukaryotic cells

More Organelles

• Lysosomes = break down lipids, carbohydrates, and proteins into small particles that can be used by the cell, they also break down “old” organelles – found in eukaryotic cells

More Organelles

• Cytoskeleton = helps the cell maintain shape and helps with movement – Made of microfilaments and microtubules – found in eukaryotic and prokaryotic cells

Page 6: 7.2 Cell Structure Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells Organelles “little organs”

More Organelles

• Centrioles – found in eukaryotic cells – help with cell division – found next to the nucleus

Page 7: 7.2 Cell Structure Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells Organelles “little organs”

More Organelles

• Ribosomes = where proteins are assembled – found in prokaryotic and eukaryotic cells

Page 8: 7.2 Cell Structure Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells Organelles “little organs”

More Organelles

• Endoplasmic Reticulum (ER) – found in eukaryotic cells

• 2 types – • 1. Smooth ER – enzymatic functions• 2. Rough ER – has ribosomes on its surface,

makes proteins

More Organelles

• Golgi Apparatus (Golgi Body) – modifies sorts, and packages protein (post office) – found in eukaryotic cells

Page 10: 7.2 Cell Structure Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells Organelles “little organs”

More Organelles

• Chloroplast – capture light energy and convert it into chemical energy– Contain chlorophyll – makes a plant green– Found in eukaryotic plant cells and some protist

cells

More Organelles

• Mitochondria – converts energy – found in eukaryotic cells

Page 12: 7.2 Cell Structure Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells Organelles “little organs”

More Organelles

• Cell Wall – protection – found in prokaryotic cells and plant cells

Page 13: 7.2 Cell Structure Cytoplasm = portion of the cell outside the nucleus – found in eukaryotic and prokaryotic cells Organelles “little organs”

More Organelles

• Cell (plasma) membrane – regulates what enters and leaves the cell (bouncer)

• Made of a lipid bilayer (phosphorous & lipids)• (phospholipid)

Cell MembraneLipidsHydrophobic – Afraid of WaterHydrophilic – Love Water

Fluid Mosaic Model – Proteins embedded in layer make it look like artLayer is selectively permeable – can chose what enters and leaves.
