Given this result, let's craft a detailed, step-by-step solution for your question. Here's how you can set up and complete the table with a suitable heading, followed by descriptions for how each organism's gas exchange organs meet the requirements for efficient gas exchange:
### Heading: Requirements for Efficient Gas Exchange in Various Organisms
| Organism | Gas Exchange Organ | Large Surface Area | Thin | Permeable and Moist | Well Ventilated | Transport System | Protected |
| --- | --- | --- | --- | --- | --- | --- | --- |
| Earthworm | Skin | Yes, the skin has a large surface area relative to the volume of the organism. | Yes, the skin is thin facilitating diffusion. | Yes, the skin secretes mucus, keeping it moist and permeable. | No, earthworms rely on their environment to be moist. | Yes, blood capillaries under the skin transport gases. | Yes, living in soil helps protect the skin. |
| Insect | Tracheal System (tracheae and spiracles) | Yes, the tracheal system is extensive, providing a large surface area. | Yes, tracheoles are thin-walled. | Yes, the tips of tracheoles are moist, allowing gas exchange. | Yes, movement of the insect ventilates the tracheal system. | No, gases are directly transported without a circulatory system. | Yes, spiracles can close to prevent water loss and entry of particles. |
| Fish | Gills | Yes, gill filaments and lamellae provide a large surface area. | Yes, gill membranes are very thin. | Yes, water passing over the gills keeps them moist. | Yes, water is continuously moved over the gills. | Yes, a circulatory system transports gases to/from cells. | Yes, gill covers protect the delicate gills. |
| Dicotyledonous Plant (indicating leaf structures) | Leaves | Yes, leaves have a large surface area provided by many cells and air spaces. | Yes, mesophyll cells are thin. | Yes, the cell walls are permeable and surfaces are moist for gas exchange. | No, but stomata on leaves open and close. | No, gases diffuse into cells directly. | Yes, the cuticle and wax layers protect leaf surfaces. |
This table is now filled with appropriate information that explains how each organism’s gas exchange organs meet the requirements for efficient gas exchange.
