Question | Answer |
---|---|
What are cells? | Cells are the smallest functional units of living organisms. |
Within each cell, what is there? | There are smaller working structures that carry out specific functions within the cell (organelle). |
What do the set of organelles do? | They keep the cell functioning and contributing to the whole organism. |
What are the gate keeper(s)? | Cell Walls and Cell Membranes |
What is a cell membrane? | A thin, flexible barrier that surrounds the cell and controls what goes into and out of the cell (selectively permeable). |
What is a cell wall? | A rigid supporting layer that surrounds the cell of plants. Help with overall shape and structure. |
What is cytoplasm? | A gel like substance found within the cell that holds the organelles in place. |
What is a nucleus? | It contains the cells genetic information (DNA); one of the largest organelles in a call; the control center or “boss”. |
What is mitochondria? | The “powerhouse” of the cell; convert energy stored in food to energy the cell can use. |
What is the chloroplast? | An organelle found in plants that that helps them make food (photosynthesis). Contains chlorophyll (green pigment). |
What is the lysosome? | The cells recycling center or trash truck or recycling center; they break down food particles into smaller pieces and breakdown old worn-out cell parts. |
What is the vacuole? | The storage site for food, water, and waste. |
Name some differences between plant and animal cells? | General shape, plant cells have a cell wall and animal cells do not, plant cells have chloroplasts and animal cells do not, and plant cells have a larger, more centralized vacuole. |
What do specialized cells do in complex organisms? | Different types of cells can be observed. |
Each type of cell does what? | One type of job, while other types of cells do other jobs. |
They differ in structure and? | Differ in function |
Cells make up an organism and also... | Create tissues. Tissues working together create organs. Organs working together create organ systems. Organ systems working together create organisms. |
