Protista differs from monera in having
cell wall
autotrophic nutrition
flagella
nuclear membrane
D.
nuclear membrane
All single-celled eukaryotes are placed under protista. Phylogenetically the kingdom protista acts as a connecting link between the prokaryotic kingdom-Monera and the complex multicellular kingdoms- Fungi, Plantae and Animalia.
Protistan cell body has a well defined nucleus and other membrane- bound organelles. It is surrounded by plasmalemma (cell membrane). It consists of cilia and flagella. It has nucleus, nucleolus and nucleoplasm. Monerans lack nuclear membrane.
Mycorrhiza is correctly described as
symbiosis of algae and fungi
relation of ants with the stem of some trees
parasitic association between roots and some fungi
symbiotic relationship between fungi and roots of some higher plants
Identify the accurate explanation of mesosome. It is
a specialised structure of prokaryotic cell formed by extension of plasma membrane into the cytoplasm
the middle layer of the prokaryotic cell wall
the organelle of eukaryotic cell which helps in lipid synthesis
the middle layer of eukaryotic cell wall.
Yeast is not included in protozoans but in fungi because
it has chlorophyll
it shows saprotrophic mode of nutrition
it has eukaryotic organisation
cell wall is made up of cellulose and reserve food material as starch

Deuteromycetes are known as fungi imperfecti because
their zygote undergoes meroblastic and holoblastic cleavage
only asexual stages are known
they have aseptate myceliun
they are autotrophic
The microscope usually used for seeing living cells or tissues is
compound microscope
electron micrscope
phase contrast microscope
light microscope.
