Grade 10 Bio:Cells
| Question | Answer |
|---|---|
| Cell Theory | all living things are made up of one or more cells, they are the basic unit of life, all cells come from pre-existing cells |
| Cell Cycle | interphase, prophase, metaphase, anaphase, telophase, cytokines |
| Mitosis | prophase, metaphase, anaphase, telophase (PMAT) |
| Interphase | DNA is replicated, cell prepares for mitosis |
| Prophase | centrioles move to opposite poles, chromatin condenses into chromosomes, spindle fibres form in between the centrioles, nuclear membrane begins to dissapear |
| Metaphase | Spindle fibres pull chromosomes into a line across the equator |
| Anaphase | Single stranded chromosomes are pulled to opposite poles by contracting spindle fibres |
| Telophase | Two nuclear envelopes form |
| Cytokenisis | Occurs after mitosis, final step of cell division, two daughter cells form |
| cytoplasm | allows organelles to move around |
| cell wall | in plants only, supports cell, protects cell |
| Nucleus | contains DNA |
| mitochondria | powerhouse of the cell, converts stored glucose into energy |
| endoplasmic reticulim | transport protein through cell |
| golgi bodies | collect materials that need to be removed from the cell |
| Vacuole (plant) | one large vacuole, contains substances, maintains internal fluid pressure |
| Vacuole (animal) | Multiple smaller ones, contains and removes unwanted substances, internal fluid pressure |
| chloroplasts | contains chlorophyll, makes plants green |
| Hierarchy | more complex structures at the top and simpler below it |
| Tissue | animals and plants are made of it, consisting of specialised cells |
| organ | part of an organism that has a vital role |
| organ system | group of organs that work together to preform one or more functions |
| Epithelial tissue | covers internal organs (Epidermis) |
| Muscle Tissue | gives body ability to contract and move (bicep) |
| Connective Tissue | connects/support other tissues or organs (cartilage) |
| Nerve Tissue | to recive stimuli and send impulses to brain (spinal cord) |
| Stem cells | cells that can turn into and divide into any cell that is needed |
| Benign | non cancerous/ does not spread |
| Malignant | cancerous/ has not spread yet |
| Mestatic | cancerous/ has spread |
| Radiation Treatment | high energy rays to kill cells |
| chemotherapy | anticancer injection to kill cells |
| surgery | physically removes tumour |
