Answer:
See Below.
Explanation:
The main function of the plants leaves is to create it's own food source via photosynthesis which produces glucose as one of it's products. Transpiration also occurs in the plant leaves where water evaporates out of the leaf increasing the concentration gradient, allowing more water to move up via the xylem via a column of water.
D. Water light and CO2 are needed for the process of photosynthesis.
Answer:
Answer is option A.
Orchid bees are to Brazil nut trees as breezes are to pine trees.
Explanation:
In Brazil nut trees, the female orchid bees act as pollinators that help in pollination. In pine trees, wind or breeze helps in pollination.
Pine trees are gymnosperms and so they do not have flowers to attract pollinators like bees or butterflies or birds. They are wind-pollinated. Pine trees are monoecious i.e., both male and female reproductive structures (pine cones) are present on the same tree.
The male cones (catkins) produce pollen grains that are lightweight, less sticky and have air bladders or small wing-like structures. As a result of these features, the pollen grains can be easily carried and dispersed by the breeze. In order to prevent self pollination (pollen falling on the female cones of the same tree), the male cones are normally located on the lower branches of the pine tree.
The female cones are located on the upper branches of the tree and the center of the cone contains eggs or ovules. The pollen grains that are carried by the wind, fall on the female cone of another pine tree. Each pollen grain grows a pollen tube into the center of the cone and the nucleus cell of the pollen travels through the tube and reaches the egg, where it combines with the egg to form an embryo. The embryo eventually grows into a seed. The seeds of pine trees are then dispersed by wind or animals such as squirrels.
Answer:
There are many green house gases and carbondioxide is one of them. Green house gas has the ability to stop the heat from going to the atmosphere. This heat energy reduces the atmospheric carbondioxide to dissolve in the ocean water so more concentration of carbondioxide is present in the atmosphere which stop the reflected sunlight rays into the space and thus increase the temperature of the earth surface. This increase in temperature called global warming.
