Today we focused on the organelles of a eukaryotic cell. Below you will find the vocabulary associated with each organelle.
- synthesis: the process of producing or making something
- cell membrane - the part of the cell which separates the external environment from the cytoplasm
- cell wall - in plant cells, a tough, rigid structure made up of cellulose which is outside of the cell membrane
- chloroplast - an organelle present in algae and plant cells that contains chlorophyll and is involved in photosynthesis
- cytoplasm - gel-like substance in which all cellular components outside the nucleus are immersed.
cytoskeleton - protein lattice structure which gives shape to our cells.
- Golgi apparatus - an organelle in the cytoplasm that packages proteins and carbohydrates into vesicles for export from the cell.
- mitochondrion - organelle where final cellular respiration steps takes place
- nucleus - organelle which contains the DNA, organized into chromosomes; site of mRNA synthesis from DNA.
- organelles - membrane-bound structures found inside the cell cytoplasm.
- ribosome - subcellular structures (typically thousands per cell) that provide sites for protein synthesis; occur in cytoplasm and on rough endoplasmic reticulum.
- rough endoplasmic reticulum (RER) - a system of membranous tubes and sacs containing ribosomes which function in the manufacture of membrane-bound proteins.
- smooth endoplasmic reticulum (SER) - a system of membranous tubes and sacs that functions in lipid synthesis.
- vacuole - large organelle in plant cells that contains water, often having dissolved pigments, waste materials, or other substances
The Homework Assignment for this evening was to:
