Plants are the organisms that produce oxygen, or O2. To do this, they go through a process called photosynthesis. They take carbon dioxide, water, and sunlight, and convert it into oxygen and glucose (sugar). Without plants, you, me, your pet, and all other living organisms wouldn't have oxygen :) hope this helped!

The phloem carries important sugars, organic compounds, and minerals around a plant.

What part of the respiratory tract is considered the respiratory zone?
Lorico [155]

Answer:

D. Alveoli

Explanation:

Functionally, the respiratory system is separated into a conducting zone and respiratory zone:

Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.

Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).

The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
