Aim: How do plant & animal cell organelles maintain homeostasis?
DO NOW:Read the “Cell Theory Rap” handout & on loose-leaf, explain why we looked at this rap, choose 2 organelles & write down their functions.

Organelles
• “mini-workers” inside of cells that have specific jobs
• Lie in the cytoplasm of both animal & plant cells (eukaryotes)

Nucleus
• Brain of the cell• Contains DNA or genetic instructions (Nucleic
Acid)• Has a membrane with pores

Ribosomes
• Make proteins• Found freely in cytoplasm or attached to
endoplasmic reticulum
![Page 7: Aim: How do plant & animal cell organelles maintain homeostasis?](https://reader035.vdocuments.us/reader035/viewer/2022081503/5a4d1b027f8b9ab0599870e9/html5/thumbnails/7.jpg)
Mitochondria
• Site of cellular respiration (chemical reaction)• ATP Energy producing organelle• Powerhouse of the cell
![Page 8: Aim: How do plant & animal cell organelles maintain homeostasis?](https://reader035.vdocuments.us/reader035/viewer/2022081503/5a4d1b027f8b9ab0599870e9/html5/thumbnails/8.jpg)
Vacuoles
• Storage sacs for food or water or excess waste, that will eventually be eliminated
![Page 9: Aim: How do plant & animal cell organelles maintain homeostasis?](https://reader035.vdocuments.us/reader035/viewer/2022081503/5a4d1b027f8b9ab0599870e9/html5/thumbnails/9.jpg)
Endoplasmic Reticulum
• Cellular highway• Allows for more efficient transport inside of
cells• 2 Types: Smooth & Rough• Rough: contains ribosomes, which make
proteins• Smooth: no ribosomes

Golgi Bodies / Apparati
• Packaging organelle for proteins (sorts, modifies & packs proteins)
![Page 12: Aim: How do plant & animal cell organelles maintain homeostasis?](https://reader035.vdocuments.us/reader035/viewer/2022081503/5a4d1b027f8b9ab0599870e9/html5/thumbnails/12.jpg)
Lysosomes
• Located in both animal and plant cells• Contain digestive enzymes for breakdown of
wastes (Ex. damaged cells or old cell parts)
![Page 13: Aim: How do plant & animal cell organelles maintain homeostasis?](https://reader035.vdocuments.us/reader035/viewer/2022081503/5a4d1b027f8b9ab0599870e9/html5/thumbnails/13.jpg)
Centrioles
• Only in animal cells• Look like cylinders• In pairs, near the nucleus• Involved in cell division
![Page 14: Aim: How do plant & animal cell organelles maintain homeostasis?](https://reader035.vdocuments.us/reader035/viewer/2022081503/5a4d1b027f8b9ab0599870e9/html5/thumbnails/14.jpg)
Chloroplast
• Only in Plant Cells• Site of Photosynthesis (chemical reaction)• Food (Glucose) Producer• Contains chlorophyll pigment (allows for
absorption of sunlight)

Cell Membrane
• Barrier between inside & outside of cells• Regulates what enters & exits cells
![Page 17: Aim: How do plant & animal cell organelles maintain homeostasis?](https://reader035.vdocuments.us/reader035/viewer/2022081503/5a4d1b027f8b9ab0599870e9/html5/thumbnails/17.jpg)
Cell Wall
• Made of cellulose (tough carbohydrate)• Lies outside the cell membrane in plant cells
and bacteria, fungal organisms and some protists
• Offers Support & Protection

Cytoplasm
• Similar function to that of the human body’s circulatory system
• Site of most chemical reactions in a cell• Holds organelles in place• Mostly made of water• “gel-like” fluid that surrounds the nucleus
