characteristics features of kingdom protista and kingdom fungi
Answers
Answer:
kingdom protista
These are usually aquatic, present in the soil or in areas with moisture.
Most protist species are unicellular organisms, however, there are a few multicellular protists such as kelp. Some species of kelp grow so large that they exceed over 100 feet in height. (Giant Kelp).
Just like any other eukaryotes, the cells of these species have a nucleus which is bound by organelles.
They may be autotrophic or heterotrophic in nature. An autotrophic organism can create their own food and survive. A heterotrophic organism, on the other hand, has to acquire nutrition from other organisms such as plants or animals to survive.
Symbiosis is observed in the members of this class. For instance, kelp (seaweed) is a multicellular protist that provides otters protection from predators amidst its thick kelp. In turn, the otters eat sea urchins that tend to feed on kelp.
Parasitism is also observed in protists. Species such as Trypanosoma protozoa can cause sleeping sickness in humans.
kingdom fungi:
Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.
They may be unicellular or filamentous.
They reproduce by means of spores.
Fungi exhibit the phenomenon of alternation of generation.
Fungi lack chlorophyll and hence cannot perform photosynthesis.
Fungi store their food in the form of starch.
Biosynthesis of chitin occurs in fungi.
The nuclei of the fungi are very small.
During mitosis, the nuclear envelope is not dissolved.
The fungi have no embryonic stage. They develop from the spores.
The mode of reproduction is sexual or asexual.
Some fungi are parasitic and can infect the host.
Fungi produce a chemical called pheromone which leads to sexual reproduction in fungi.
For eg., mushrooms, moulds, yeast.
