B)using another for one's own benefit; having to do with an organism that draws benefit from another
C)a part of a cell which has a particular function
D)a single-celled organism that has characteristics of both plants and animals
E)another term for a moneran; a single-celled algae
A) the process by which sunlight is turned into sugars within a plant
The correct answers are C) special cells located on the underside of a leaf and E) cells that allow water and air to pass into and out of the leaves in a process called transpiration.
To find the answer to this question, we can break it down and eliminate the incorrect options.
Option A) cells that contain chloroplasts: Stomata are not specifically connected to the presence of chloroplasts. Chloroplasts are the organelles responsible for photosynthesis in plant cells, which occurs in the leaf cells but not specifically in stomata.
Option B) special cells that store water: While plants have cells that store water such as the ones found in plant tissues like the storage parenchyma, stomata are not directly involved in water storage.
Option C) special cells located on the underside of a leaf: This option is correct. Stomata are specialized cells found primarily on the lower surface of leaves (although they can also be present on stems and other plant organs). They are typically surrounded by guard cells, which regulate their opening and closing.
Option D) cells where food is made: The cells responsible for food production in plants are mainly the mesophyll cells of the leaf, where photosynthesis takes place. Stomata are not directly involved in food production.
Option E) cells that allow water and air to pass into and out of the leaves in a process called transpiration: This option is correct. Stomata facilitate the exchange of gases (such as carbon dioxide and oxygen) and water vapor between the plant and its environment. This process is known as transpiration.
By analyzing each option and understanding the role and location of stomata, we can identify options C) and E) as the correct answers.
