| Question | Answer |
|---|---|
| plasmodesmata | small channels that connect the cytoplasm of neighboring plants cells to each other. Selectively permeable. |
| peroxisome | contain enzymes that are responsible for many metabolic reactions. Catabolizes fatty acids |
| Golgi Vesicle | membrane bound organelles that originate from the Golgi when the membrane of the Golgi pinches off. Vesicles contain and transport substances. |
| Golgi body | receives, modifies, and ships out proteins and lipids from the RER and SER to other parts of the cell or out of the cell. |
| central vacuole | functions to store was well as ions and waste |
| mitochondria | responsible for creating cellular energy through the synthesis of ATP |
| chloroplast | Performs photosynthesis in plant cells. Uses green pigment (chlorophyll) which is capable of capturing light energy |
| Cytoskeleton | Protein fibers that secure and move organelles around the cell, and helps give a cell its shape. 3 components: microtubules, microfilaments, and intermediate filaments. |
| Nuclear pores | channels through the nuclear membrane that allow RNA and ribosomes to leave the nucleus and proteins and molecules from the cytoplasm to enter the nucleus. |
| nuclear membrane | controls the traffic off substances in and out of the nucleus. |
| DNA in nucleoplasm | In the nucleus. DNA: codes for genetic information |
| Nucleolus | dense section in the nucleus. Creates and assembles ribosomes |
| Nucleus | stores and protects the DNA within it. Site of ribosomal assembly(within the nucleolus). Site of RNA synthesis |
| rough endoplasmic Reticulum | called "rough' because it has ribosomes embedded on its membrane surface. Forms vesicles around proteins made by ribosomes and ships them to the ER for further processing. |
| smooth endoplasmic reticulum | "smooth" because it lacks ribosomes. Breaks down drugs, alcohol, and toxins. Makes lipids, fats, and steroids before delivery to the Golgi body./apparatus. |
| ribosomes | made by the nucleolus. Make proteins |
| Cytoplasm | where the cell organelles are stored. Where metabolism and specialized functions of the cell are carried out. |
| Cell wall | outermost coating of the plant cell. Rigid and tough- its main role is that of structural support and physical protection. Made by cellulose. |
| Cell/plasma membrane | semipermeable membrane that surrounds the cytoplasm of the cell that separates the interior from the external environment . |
| Prokaryotic cell-Pillus | short hair like structures on the cell surface that play a role in movement. Adhere to surfaces |
| Prokaryotic cell-capsule | protective capsule layer that surrounds the cell walls called lipopolysaccharide layer |
| Prokaryotic cell-fimbriae | allowing bacteria to colonize environmental surfaces or cells. |
| Prokaryotic cell-plasmid | small DNA molecule that is physically separate from and can copy chromosomal DNA within a cell. |
| Prokaryotic cell-flagella | whip like structure appendage that propels the cell |
| Common Bacteria Shapes | Coccus, Bacillus, Vibrio, Spirillum, Spirochete |
