cell organelles
| Question | Answer |
|---|---|
| cell wall | fairly rigid stucture located outside of the plasma membrane, provides protection and support/ found in plant animal and bacteria |
| cytoplasm | clear, gelatinous,fluid in cells, suspends organelles, site of many chemical reactions/ found in plant animal and bacteria |
| nucleolus | prominent organelle in the center of teh nucleus, responsable for making ribosomes/ found in plant and animal |
| microfilaments | small, thin, solid proteins, anchor and support organelles/ found in animal and plant |
| endoplasmic reticulum | extensive network of membranes with accordian folds that attatch to the nuclear membrane, site of cellular reactions and responsible for transporting materials within a cell |
| smooth e.r. | no ribosomes, lipid components of cell membrane made here, breaks down waste and poison |
| nuclear pores | holes in nuclear membrane allow substances to pass through/ found in animal and plant |
| lysosomes | membrane bound sac containing digestive enzymes, digests worn out organelles, food, and engulfs viruses and bacteria "suicide sacs"/ found in animal and plant |
| vacuoles | membrane bound compartments, temp stores food, enzymes,/ found in plant and animal |
| ribosomes | non membrane bound organelle composed of rna and proteins, responsible for making protein/ found in animal plant and bacteria cells |
| cytoskeleton | cellular framework composed of microtubules and microfilament, support structure for teh cell/ found in animal and plant |
| plasma membrane | flexible boundary between the cell and teh environment composed of phospholipid bilayer, allow materials to enter and exit cell |
| chloroplast | outer and inner membrane that contains green pigment called chlorophyll, captures light energy and converts it to chemical energy/ found in plants |
| centriole | pair of small cylindrial structures composed of microtubules used in cell division/ found in animal cells |
| nuclear envelope | double layers membrane, seperates the nucleus from cytoplasm/ found in plant and animal |
| golgi apparatis | series of flattened membrane bound sacs arranged like a stack of pancakes, modifies materials then packages and secretes them, packages are called vesicles/ found in animal and plant |
| nucleus | control center of the cell, contains cells dna and with it the instructions for making proteins/ found in animal and plant |
| rough e.r. | studded with ribosomes and involved in the synthesis of proteins |
| microtubles | thin, hallow, cylinders made of proteins maintain the shape of the cells and serves as tracts on which the organelle move/ found in animal and plant cells |
| flagella | long whiplike projections located on outside of cell, used in locomotion/ found in animal and bacterial cells |
| mitochondria | membrane bound organelle with a highly folded inner membrane, transforms energy from food sources, cells "powerhouse"/ found in animal and plant |
| cilia | short, hairlike structures located on the outside of the cell, used in locomotion and feeding/ found in animal plant and bacterial cells |
| plastid | membrane bound organelle that contains pigments usually red or brown, chloroplast is a type of plastid/ found in plants |
| chromatin | strands of dna located in the nucleus, when cells divide this condenses to form chromosomes/ found in animal plant and bacterial cells |
