If you you get 40 in plants, leaves are the primary photosynthetic organ. the diagram shows a cross section of a leaf; discuss what would happen if the guard cells permanently blocked the stomata on the underside of the leaves of a plant. include at least 2 possible scenarios that could happen to the plant if the stomata were blocked. number each example, and provide specific examples supporting your answers in complete sentences.

Hey there!


1. Taking in oxygen is very important because it allows your cells to do things, like make energy from the food you eat. Plants 'breathe' too, but they do it through tiny openings in leaves called stomata (singular: stoma). Stomata open and close to allow the intake of carbon dioxide and the release of oxygen.

Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.If the guard cells permanently blocked the stomata, essential gas(es), such as carbon dioxide, would not have access to the stoma. Thus being, the plant would not be able to go through photosynthesis and therefore die.

2.As stated before, the stomata are openings on the bottom of leaves that allow for gas exchange and water from the plant tissue can evaporate through them. If the stomata are open all the time water from the plant will diffuse into the air based on humidity, basically if there is more water in the leaf than in the air, water will leave the leaf until the air around it has the same amount of water as in the leaf. SO, if the air is dry the plant could lose a lot of water, which can eventually also lead to death.

I hope I was able to explain this in a way you can understand. (I labeled the scenarios to make it easy for ya *wink*)

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
