The leaf of a plant is protected by a waxy substance called the cuticle. This prevents the air, containing carbon dioxide, from entering the leaf. Since carbon dioxide is one of the primary components that drive photosynthesis, plant leaves adapted and evolved these highly specialized structures to allow the passage of carbon dioxide.


Exchange in Plants. STUDY. PLAY. Terms in this set (...) How does carbon dioxide enter the leaf and oxygen leave? Diffusion through the open stomata. CO2 from the air diffuses into the air spaces and into the leaf cells down a concentration gradient.Simultaneously, Oxygen ( from photosynthesis) is removed by diffusion into the surrounding air ...


Where does carbon dioxide enter the leaf in photosynthesis? Through stomata, which are small mouth-like structures on the leaf responsible for gas exchange (O2 and CO2).


If the stomata are closed carbon dioxide cannot enter the leaf and photosynthesis will slow down because there isn't enough CO2. Trace the path for reactants for photosynthesis as they enter the leaf. CO2- Enter though the stomata -air spaces-palisade mesophyll-chloroplasts

Carbon dioxide enters the leaf through stomata. Stomata are tiny little holes that are on the bottom of the leaf. Oxygen leaves the plant during photosynthesis. It leaves because during the light dependent stages, photons of light separate water into oxygen and hydrogen. The oxygen then diffuses out of the plant releasing oxygen into the air.

No, Carbon Dioxide does not enter the leaf through the xylem or phloem. Leaves take in Carbon Dioxide from the air and produce oxygen through tiny pores in the leaf known as stoma or (plural) stomata. Stomata is the site of gas exchange. It also enables water vapour to be lost which is directly realted to the process of transpiration.


Leaves and leaf structure Most plants have leaves as their organs of photosynthesis. A leaf may be viewed as a solar collector crammed full of photosynthetic cells. The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, glucose and oxygen, leave the leaf.


Part A: Trees - The Carbon Storage Experts. Have you ever stood next to a tree and wondered how this tree got to be so big? In California, some Giant Sequoia trees are more than 2000 years old and grow to be over 300 feet tall.
