Transcript of 1. Plasma Membrane Function – physical barrier for the cell; separates internal and external...
1. Plasma Membrane• Function – physical barrier for the cell; separates
internal and external environments; selective permeability
• Location – surrounding the cell, outer surface
2. Nucleus– Function – control center of the cell; contains
DNA; filled with a fluid called nucleoplasm– Location – center of the cell
3. Nuclear Envelope• Function – keeps nuclear contents separate from the
rest of the cell; allow for information to get into and out of the nucleus when necessary
• Location – surrounding the nucleus
Nuclear Envelope with pores
4. Nucleolus• Function – dense area within the nucleus; produces
ribosomal RNA• Location – center of the nucleus
5. Mitochondria– Function – site of cellular respiration; the transfer
of energy from organic molecules to ATP– Location – scattered in the cytoplasm
6. Ribosomes• Function – sites of protein synthesis• Location – in cytoplasm and on rough endoplasmic
reticulum
7. Rough Endoplasmic Reticulum
– Function – allow for the transport of substances throughout the cell
– Rough ER – contains ribosomes; functions in protein synthesis
– Location – surrounding the nucleus
8. Smooth Endoplasmic Reticulum
• Function – allow for the transport of substances throughout the cell
• Smooth ER – doesn’t have ribosomes; functions in lipid synthesis
• Location – surrounding the Rough ER
9. Golgi Apparatus• Function – packaging, modifying and shipping of
cellular products• Location - in cytoplasm near endoplasmic reticulum
10. Lysosomes– Function – break down/digest bacteria, old or
damaged organelles– Location – scattered in the cytoplasm
11. Peroxisomes• Function – produce hydrogen peroxide when they
break down alcohol and engulf bacteria• Location – scattered in the cytoplasm
12. Microtubules/Microfilaments• Function – Hollow tubes made of protein, hold
organelles in place, maintain cell shape• Location – Radiate outward from the center called
centrosome near the nucleus
13. Cilia and Flagella• Cilia - Short and present in large numbers• Flagella - Long extensions of the cell, usually
one that helps with the cell moving• Function – Assist in movement• Location – Outside of the cell
14. Centrioles• Function – Two short cylinders of microtubules that
organize cell division• Location – Near the nuclear envelope
*Only in animal cells*
