| Question | Answer |
|---|---|
| materi8als inside the cell membrane containing the necessary components of cell life (gel-like) | cytoplasm |
| fluid substance inside the nucleus | nucleoplasm |
| means the cell's membrane generally regulates which substances pass in and out of the cell | selectively permeable |
| substance composing every living cell and a nutrient nevessary for cell growth and repair | proteins |
| membrance bound structures containg digestive enzymes and help prevent the cell from digesting itself | lysosome |
| energy producing structures within the cell | mitochondria |
| control center of the cell | nucleus |
| fluid-filled "bags" used for storage in the cytoplasm | vacuole |
| body within the nucleus (contains RNA) | nucleolus |
| network of membranes functioning in transport of materials within the cytoplasm | endoplasmic recticulum |
| ability of a cell to maintain a stable internal environment changes occur in the outside environment (balance) | homeostasis |
| substances in blood protein which help maintain neutral pH in the plasma | buffers |
| subcellular part that has a special cellular function(little organs) | organelle |
| building blocks of protein | aminno acids |
| strands of DNA making up a chromosome | chromatid |
| organelles that deliver substances released by the er of the cell and where carbohydrates synthesis occurs (packaging center) | golgi body |
| cells which lack a nucleus and other membrance bound structures | prokaryotic cells |
| elongated structures containing DNA and pass on traints to a new cell | chromosome |
| membrance separating the nucleus from the rest of the cell and regulates the passage of materials in and out of the nucleus | nuclear membrane |
| outer barrier that regulates what enters and leaves the cell | cell membrane |
| tubular structure that function in cell division | centriole |
| straight cylinders of protein that give ridigity to the cell )skeletal system) | structures that make or store food in plant cells |
| structure which holds chromatids together | centromere |
| short, thin protein fibers necessary for certain aspects of cell movement (muscular system) | microfilaments |
| spherical bodies which contain RNA and produce proteins for the cell | ribosomes |
| cells having a nucleus and membrane bound structures | eukaryotic cells |
| structures that make or store food in the plant cells | plastids |
