Stomata are tiny openings found in plant leaves. specialized cells known as guard cells surround the stomata and open and close the openings. when it is very hot, plants may close their stomata to prevent water loss. when plants close their stomata, what else is affected?
a) plants cannot take in the carbon dioxide they need for photosynthesis.
b) plants cannot take in the sunlight they need for photosynthesis.
c) plants cannot release glucose made in photosynthesis.
d) plants cannot take in water from the air.

A)Plants cannot take in the carbon dioxide they need for photosynthesis.

Explanation:

Stomata are tiny openings found in plant leaves. Specialized cells known as guard cells surround the stomata and open and close the openings. When it is very hot, plants may close their stomata to prevent water loss. When plants close their stomata, they will prevent water loss but photosynthesis might be affected.

Plants open and close their stomata for the exchange of oxygen and carbon dioxide during photosynthesis.

Answer from: froyg1234

Answering the question, when plants close their stomata, plants cannot take in the carbon dioxide they need for photosynthesis. Therefore, the correct answer is A.

Stomata can be defined as tiny openings in plant tissue that allow the exchange of carbon dioxide and oxygen. It is found in plant leaves and stems. There is a presence of some specialized cells within the stomata and the cells are responsible for the opening and closing of the stomatal pores.

Further Explanation

Stomata enable plants to absorb carbon dioxide which is important in the process of photosynthesis (the process by which green plant produce their food)

Stomata close during hot or dry conditions to limit the loss of water. In other words, they close when there is a hot or dry condition to reduce water loss.

The plants present on the land possess huge numbers of stomata on their leaves and most of the stomata can be found on the underside of the plant leaves. The position of the stomata also reduces their exposure to heat and wind. They are located on the upper surface of leaves in aquatic plants.

Therefore, when plants close their stomata, plants cannot take in the carbon dioxide they need for photosynthesis.

Answer from: Quest

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
