The document summarizes the structures and functions of various cell organelles:
- The cell membrane is a phospholipid bilayer that protects the cell and regulates what enters and exits.
- The mitochondria have an inner and outer membrane and produce ATP through cellular respiration.
- The endoplasmic reticulum transports and packages proteins, lipids, and other molecules. The rough ER has ribosomes and produces proteins.
- Ribosomes are found free in the cytoplasm or attached to the ER and are the site of protein synthesis.
- The Golgi body modifies and packages proteins and lipids for transport within the cell.
- Vesicles and vacuoles transport materials within the cell for storage or waste disposal. Lysosomes
25. Polyribosomes Structure: Many ribosomes grouped together, ribosome cluster Functions: Work together to read one strand of RNA - increases speed & # of proteins produced
47. Cell Wall Structure: Composed of cellulose Located outside of cell membrane Function: Provides structure, protection, rigidity to plant cells (not found in animal cells) Permeable
49. Chloroplast Structure: Double membrane bound organelle Stroma: space within chloroplast Thylakoid stacks: where reactions occur - contain chlorophyll Function: Site of PHOTOSYNTHESIS within plant cells (produces glucose)
