Leaves of these plants DO NOT show Kranz anatomy. Leaves of these plants show Kranz anatomy.
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Answer:
Only members of the phylum Porifera (sponges) have no body plan symmetry. There are some fish species, such as flounder, that lack symmetry as adults.
Porifera is animals without tissues. These animals are asymmetrical.
There is an evolutionary reason why such mechanisms would only work within species: Fish would get an advantage (as a population) from warning their co-specifics, but not from warning other species. So they would (through the process of evolution) tweak their signals to be only readable by the same species.
