Answer:
1. Atmosphere and ecosystem
2. Carbon/CO2 is absorbed by the plants and then released as oxygen.
3. Carbon is used in the cellular respiration process to make ATP.
4. Decomposers break down dead material and release CO2 in that process into the atmosphere for plants to use that carbon for photosynthesis again.
Answer:
B. stomata.
Explanation:
Stomata are openings in the surface of the plant epidermis through which gases and water vapor pass. They are formed by two elongated cells whose shape is similar to bean grain or dumbbell depending on the species. These cells are called guard cells, and in their midst there is a slit called the ostiole.
The stomata make the exchanges between the external and internal environment of the plant. They regulate the size of the opening, so it is possible to increase or decrease the rate of perspiration of the plant.
Stomata are usually located at the bottom of the leaf, but in aquatic plants such as the water lily they are at the top and still in vertical growing plants on both sides.
Yes of course!
In the most catastrophic case, it can kill hundreds of thousands through hurricanes and the things that come with hurricanes.
Droughts can cause death by both dehydration and starvation if the rain is the only dependable source of arrogation
Too much rain causes floods which can be fatal too
Answer:
C. their gametes do not require water for fertilization to occur.
Explanation:
Seed bearing plants are plants that produce seeds. The gametes of seed-bearing plants do no depend on water for fertilization. Fertilization could occur through the transfer of pollen from the male gametophtye to the female gametophyte through animals or wind.
Unlike other plant types like the bryophytes, they rely on water for fertilization. They so have xylem and phloem as well as other plants. They also have stems,roots and leaves like other plants.
