What's in Your Cells?
- PowerPoint
Unicellular organisms perform the same as multicellular (but they may be simpler).
Cellular respiration: where cells convert glucose into H2O & CO2 (the energy gained is stored as ATP).
Diffusion: when materials move in/out of a cell from a place of high concentration to low concentration.
Osmosis: a diffusion process in which water can pass through the cell membrane; many other materials are not allowed passage.
Peroxisomes protect cells from producing toxic hydrogen peroxide by producing enzymes that break down the compound.
Secretory vesicles carry hormones and neurotransmitters; they are produced in the Golgi Apparatus.
Centrosomes are responsible for growing microtubules that separate replicated chromosomes into daughter cells.
The cytoskeleton is comprised of microtubules, microfilaments, and intermediate fibers.
The way in which eukaryotic cells divide is called mitosis: where the nucleus divides its DNA, stretches out, and then finally separates into two cells.
In Plant Cells
A plant will wilt after the vacuole releases its store of water.
Tracheids are cells that have a thick cell wall while the other parts of the cell have shrunk, allowing water to move through the cell.
In vascular plants, or plants with stems and trunks, tracheids are formed to carry water through the plant.
Cells can have different shapes and sizes!
Humans have about 75 trillion cells in their body.
