7th grade JMS Cells and Mitosis
| Question | Answer |
|---|---|
| Controls what substances come in and out of cell | cell membrane |
| Supports and protects the plant cell | cell wall |
| Gel-like fluid where different organelles are found | cytoplasm |
| Passageways that carry materials from one part of the cell to another | Endoplasmic reticulum (ER) |
| The iner most part of the cell where ribosomes are made. | nuleolus |
| Makes proteins that the cell needs to perform activities | ribosomes |
| Packages, sends and receives proteins that the ribosomes make | golgi bodies |
| "Powerhouse" energy is produces,stored or released from here for cell activities | mitochondria |
| Photosynthesis takes place in this organelle containing chlorophyll | Chloroplast |
| The command center for the cell activities | nucleus |
| Controls what substances go in and out of the nucleus | nuclear envelope |
| Helps support the cell, stores water, sugar, starch and protein | vacuole |
| Contains chemicals that breaks down food particles and worn out cells | lysosomes |
| The process consisting of four phases during which the nucleus divides, and two genetically identical nuclei result | mitosis |
| The process by which cells increase in number | cell division |
| A stage of mitosis and meiosis when chromosomes migrate toward the poles(centrioles) | anaphase |
| One pair of duplicated chromosomes, joined at their middle by a centromere | chromatid |
| A body composed of DNA, which can be seen in the nucleus durng mitosis | chromosome |
| A mass of elonglated DNA | chromotin |
| The splitting of one cell into two. | cytokinesis |
| Deoxyribonucleic acid (DNA) | Hereitary material of which chromsomes are comprised ( made up of) |
| The stage of mitosis and meiosis in which the chromosomes line up in the middle of the cell | metaphase |
| One of may structures in a cell that performs a specific function | organelle |
| The stage of mitosis and meiosis in which chromosomes becaome visible | prophase |
| The stage of mitosis and meiosis, just prior to cytokinesis, where individual chromosomes are not visiable | Telophase |
| This stage of the cell cycle is the resting phase, cells grow to mature size, makes copy of DNA and prepares to divide into two cells | Interphase |
| These structures are formed in interphase to hold the spindle fibers | Centrioles |
