Cell organelles are small structures within cells that perform specific functions. The main organelles include the nucleus, which contains DNA and controls the cell; mitochondria, which generate energy; and the endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, chloroplasts, and cytoskeleton, each of which has a specialized function in the cell. Organelles are surrounded by membranes that allow transport of materials in and out and provide structure and protection to the organelle.
Use this presentation in conjunction with the Cell Organelle note-taking worksheet.
Emphasize word parts here: phospho= phosphate head; lipid= fatty acid tail bi= 2
Cells with more than one nucleus include muscle cells and liver cells, largely because of the massive volume of cytoplasm and number of organelles that need controlling.

AKA Golgi Complex
The image is 2D, so it must have been a light microscope or TEM. If the cell is very tiny, then a TEM was used. Otherwise, a strong light microscope could have captured this image.
Chloroplasts absorb light, which is the starts the process of photosynthesis.
Actin, also found in muscle cells, mainly help maintain cell shape in their cytoskeletal role. Microtubules mostly move organelles around the cell. Intermediate filaments also provide structural support.
