What the purpose the stomates of a plant?​

Biology

Answer:

Gaseous exchange

Explanation:

In terrestrial plants, gaseous exchange occurs mainly in leaves and to a lesser extent in the roots and stems. In leaves, the structures involved in gaseous exchange are stomata and spongy mesophyll tissues.

The stoma comprises of a stomatal pore and two specialized guard cells. The guard cells are structurally adapted by having chloroplasts, thicker, inelastic inner walls and thinner and elastic outer walls.

The stomata mostly opens during the day. They open when the guard cells are turgid.When the guard cells are flaccid, the thinner outer wall shrinks. The inner thicker walls curvature reduces causing the stomata to close.

Describe why the amount of light available to the Chlorella culture might affect the growth dynamics of the alga.
-Dominant- [34]

Answer:

See the answer below

Explanation:

The amount of light available to Chlorella culture might affect the growth dynamics of the alga <u>because the light is an important factor necessary for the synthesis of carbohydrates and other important molecules in the body of the organism.</u>

The process of synthesizing carbohydrates is termed photosynthesis and during this process, the energy of light is used to excite the photosystem of the chlorophyll of the organism, leading to the release of electrons whose energy is used to synthesize an energy molecule that is utilized in the latter part of the photosynthetic process. The entire process of photosynthesis can be summarised as an equation below:

            6CO_2 + 6H_2O + light --> C_6H_1_2O_6 + 6O_2

<em>The manufactured carbohydrates act as food for the organism and are broken down during respiration to release energy necessary to drive metabolic processes that bring about growth and development.</em>

Hence, the amount of light is an important factor that might affect the growth dynamics of all green plants, including the Chlorella.

Providing immunity by injecting the body with a weakened form a pathogen is known as
blagie [28]

Answer:

vaccination

Explanation:

The vaccination has been one of the most revolutionary inventions in the medical field. This invention helped protect people from numerous diseases, some being totally neutralized, while some having only minor effects on the human body. The vaccination basically is a way of enhancing the immune system of the body by injecting in it a weakened form of the pathogen. In this way, the weakened form of the pathogen is not capable to harm the body, and the body is not fighting against it, but instead the pathogen becomes part of the body and its defense mechanism, so when the pathogen strikes, the body has a counter attack and defeats it.

Josiah says this is a phylogenetic tree of the dinosaurs. Maleek says it is a cladogram of the dinosaurs. Who is correct?
RoseWind [281]
Hi!

Both Josiah and Maleek are correct, because phylogenic trees are a type of cladograms. =)

Explain why it is an advantage for plants to store carbohydrates as starch rather than as sugars​
Darina [25.2K]

Answer:

More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.

Explanation:

When plants have a period of dormancy to survive, they store their food as starch. They store enough of this energy so as to be able to restart with and to be able to maintain metabolism for the entire period of dormancy.

In addition, we know that starch is not water soluble, hence, lacks the ability to pull water into storage cells or cause irregularity in water balance. More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.

Glucose is not directly transported by plants to storage. Rather, in a plant stem, the form of carbohydrate being transported is sucrose and this is because it is a non-reducing and does not react with oxygen during transport in the stem to specialized storage plastids.
