Current Question (ID: 11472)

Question:

Plants can get along without respiratory organs because of the following except:

Options:

1. Each plant part takes care of its own gas exchange needs
2. Plants do not present great demands for gas exchange.
3. Gas diffusion in plants occurs easily over long distances in plants.
4. Each living cell in a plant is located quite close to the surface of the plant.

Solution:

Plants can get along without respiratory organs because gas diffusion occurs easily over long distances in plants. Plants have a unique structure that allows for gas exchange to occur throughout the entire plant. Unlike animals, which have specialized respiratory organs like lungs, plants rely on a system of air spaces and pores to exchange gases with the environment. The structure of plants includes stomata, which are small pores located on the surface of leaves and stems. These stomata can open and close to regulate gas exchange and prevent water loss. Inside the plant, there are air spaces and a network of interconnected cells that allow gases to diffuse freely throughout the plant.
