cell organelles for biology
| Question | Answer |
|---|---|
| Has a nucleiod region which contains the chromatin (DNA & Protein) | Prokaryotes |
| Form : Rigid, covering the cell membrane, made of cellulose in plants and algae(protists), made of chitin in fungi, made of peptidoglycan in bacteria. Function : protection, gives shape. Found in : plants, bacteria, fungi, some protists. | Cell Wall |
| Form : thin double layer made of lipids (fats) and proteins surrounding the cell. Function : controls what gets in and out. Protects cell from enviroment. Found in : all cells. | Cell Membrane |
| Form : jelly-like substance inside the cell, surrounding organelles, between nucleus and membrane Function : cushions and protects organelles. Found in : all cells. | Cytoplasm |
| Form : large round organelle with a nuclear membrane, nuclear pores, chromatin (chromosomes (DNA & protein)), nucleolus (makes ribosomes) Function : holds chromosomes (DNA & protein) Found in : only eukaryotic cells | Nucleus |
| Form : small round organelle in the cytoplasm and on the surface of the ER (endoplasmic reticulum) Function : makes protein molecules using instructions from the DNA (combines amino acids) Found in : all cells | Ribosome |
| Form : bean-shaped, with inner & outer membranes Function : supply energy to the cell by breaking down sugar molecules by cellular respiration. Found in : all eukaryotic cells | Mitochondria |
| Form : a folded membrane of tubes stretching between the nuclear membrane and the cell membrane Function : transports proteins, fats, and oils to where they are needed in the cell Found in : all eukaryotic cells | Endoplasmic Reticulum (ER) |
| ER w/o ribosomes | Smooth ER |
| ER w/ ribosomes | Rough ER |
| Form : folded membranes with vessicles (compartments) pinching off at the sides Function : Processes, packages and ships molecules Found in : eukaryotic cells | Golgi Apparatus |
| Form : like a vacuole, a membrane-bound compartment Function : digestion, breaks down carbohydrates, proteins, and lipid molecules into smaller molecules Found in : animal cells | Lysosome |
| Form: membranebound compart. in cytoplasm. Large¢ral in PC, yet small&numerous in AC Func: stores molecules, in plants: provide support through turgor pressure and stores waste products in anim Found: eukary cells (critical in plant, temp in animal) | Vacuole |
| Form: beanshaped w/ mult stacks of disks that contain pigment chlorophyll, green. Func.: to carry out photosynthesis Found: plants and come protists(those that carry out photosynthesis) Some prokar. can also photosyn. using a membrane called a thylakoid | Chloroplast |
| Has own DNA, separate from that of the nucleus. | Mitochondria and Chloroplast |
| Form : whip-like tail. Found in : some bacteria, some protists, animal sperm cells. | Flagellum/Flagella |
| Form : tiny, hair-like coverings on the surface of a cell. Found in : Bacteria, protists, animal epithelial cells (cells that surround organs inside and out) | Cilia |
