Explanation:
The parasites are those organisms which invade the host cell machinery to obtain nutrition, shelter and to reproduce their own progeny.
The fungi are the saprophytic organisms which obtain their food from the dead and decaying organic matter. But the fungi can also be parasitic in nature. The rust fungi produce spores which get attached to the plant surface. These spores germinate over the plant surface. They produce their germ tubes in the stomata of the leaves.
Some of the fungal strains damage the cuticle, and enter into the cells of the host plant. Some of the fungal strain also produce special structures called as haustoria which helps in deriving the nutrients from the plants.
<h2>Answer is option "A"</h2>
Explanation:
- A small proportion of water atoms contain the heavier isotopes of hydrogen and oxygen. There is a tendency for these heavier particles of water to gather in leaves during transpiration.
- This has a few fascinating repercussions, remembering impacts for the isotopic piece of natural issue, and of air-water fume, carbon dioxide, and oxygen.
- These impacts help transient recreation of atmosphere and spatial and worldly reproduction of essential creation in different manners.
- Hence, the right answer is option A "When heavy oxygen is part of water given to the plant, the plant produces heavy O2."
The force that attracts all matter to each other is gravity, i believe.
The answer is; TRUE
This is the ultimate definition of a food chain. An example is fish that are eaten by seals and the seals are preyed upon by sharks. Seals are the prey of sharks but the predator of fish. This is how energy is transferred in a food web from the primary producers (phototropic organisms) to tertiary consumers.
