cell organelles and their functions
| Question | Answer |
|---|---|
| what is a nucleus | the nucleus contains cells DNA and it is the control center of a cell (capitol building) |
| what is a ribosome | ribosomes are the sites where amino acids are hooked together to form protiens (factory) |
| what is the endoplasmic-reticulum | makes lipids breaks down foreign substances packages up protiens for release from the cell (transport system) |
| what is the mitochondria | breaks down food moleciles to make ATP or energy (power plant) |
| what is the chloroplast | the chloroplast makes food using energy of the sunlight (grocery store) |
| golgi complex is what | procesess and transports materials out of the cells (waste department) |
| what is a cell wall | a cell wall prevents the cells membrane from being torn it provides strength and support to the membrane |
| cell membrane is what | a cell membrane controls the passage of materials into and out of the cell also a barrier between cell and cell's enviornments |
| A vacuole is what | a vacuole stores water and other materials for future use |
| ukariotic has a nucleus or no nucleus? | nucleus |
| PROkariotic has a nucleus or no nucleus | no nucleus("pro" does not need a brain) |
| what is cellular resporation | the process of making energy for cells by breaking down gluclose molecules. the energy is in the form of ATP and heat. |
| what is photosynthesis? | the process in plants of changing light energy from the sun carbon dioxide and water into food in the form of a molecule called gluclose. su |
| what organelles do plant cells have that animals do not? | chloroplast and a cell wall |
| where does cellular resporation take place? | mitochondria |
| where does photosythesis take place? | in the chloroplast |
| what does the sun have that plant cells need | energy |
| what do animals have that plants need? | carbon dioxide and ATP |
| what do plants have that animals need? | oxygen and gluclose |
