| Question | Answer |
|---|---|
| What are cells? | All living organisms on Earth are made up of microscopic structures called cells |
| What are organelles? | Cells consist of smaller pieces, called organelles |
| What is cytoplasm? | Cytoplasm is a suspension fluid that houses the other organelles |
| Cell Membrance. | The cell membrane (or plasma membrane) acts as a boundary layer around the cytoplasm thus separating cells from their outside environments. |
| What is the cell wall? | The cell wall is a secretion of the cell membrane; it provides protection from physical injury, and with the vacuole, it provides structural support. |
| What is a vacuole? | A vacuole stores water and ingested food in a fluid sack. It also removes waste from cells and produces turgor pressure against the cell wall for cellular support. |
| What are lysosomes? | lysosomes contain enzymes specialized to break down ingested materials, secretions, and wastes |
| What is the mucleus? | The nucleus is like the “brain” of the cell. It contains chromosomal information on chromatin |
| What is the chromatin? | The chromatin is composed of long, thin strands of DNA which contains “instructions” that control cell metabolism and heredity. |
| What are ribosomes? | Ribosomes are RNA and protein complexes that are found in all cells. These complexes help cells during protein translation by joining amino acids together to form polypeptides. |
| What is the mitochondria? | Mitochondria act like a stomach for the cell; they take in nutrients, break them down and create energy for the cell. |
| WHat is the chloroplasts? | Chloroplasts are the food producers in a plant cell |
| What is the endoplasmic reticulum? | The endoplasmic reticulum transports chemicals between and within cells. It is important to note that all cells do not always have all the organelles. |
| What is an organ? | An organ is a group of tissues that work together to perform a specific function |
| What are organ systems? | Organ systems are the fourth, and highest, level of organization. Organ systems are composed of organs with interrelated functions. For example, the urinary system is an organ system made up of organs that produce, store, and carry urine |
| What are the various levels of organization that can be summed up by a diagram? | cells tissues organs organ systems |
| What are multicellular organisms made up of? | Multicellular organisms are made up of differentiated cells |
| What is a tissue? | Interconnected cells can perform specialized functions as a group. This group of interconnected cells is known as tissue. |
| What do organelles do to help the cell survive>? | Organelles are like the “organs” of a cell; they are groups of complex molecules that help cells survive |
| What are examples of organelles? | Cell membrane, cell wall, cytoplasm, vacuole, mitochondrion, endoplasmic reticulum, nucleus and chloroplast are examples of organelles |
| What does the golgi body do for proteins in the cell? | In addition to playing an important role in waste disposal, the Golgi apparatus also processes, sorts, and modifies proteins in cells. |
| Do cells always have all the organelles? | It is important to note that all cells do not always have all the organelles. |
| What do many organic and inorganic substances dissolved in cells allow? | Many organic and inorganic substances dissolved in cells allow chemical reactions that are necessary to maintain life to take place. |
| What is the difference between plant and animal cells? | Some animal cells also have vacuoles, but the vacuoles in animal cells are much smaller than those found in plant cells. |
