Which one exhibits the character of a protozoan during one phase of its life cycle and character of fungi in another phase of its life cycle?
(1) Water moulds
(2) Psilophytes
(3) Slime moulds
(4) Diatoms
These organisms are fungus like in one phase of their life cycle and Amoeba like in another phase of their life cycle
(1) diatoms
(2) slime molds
(3) dinoflagellates
(4) water molds
Slime moulds aren't/haven't
(1) Extremely resistant
(2) Having spores which are dispersed by air currents
(3) An aggregation called as plasmodium
(4) Photoautotrophs
The thalloid body of a slime mould (Myxomycetes) is known as:
1. protonema
2. Plasmodium
3. fruiting body
4. mycelium
Members of myxomycetes (slime moulds) move from one place to other by:
(1) Ciliary movements
(2) Cyclosis
(3) Amoeboid movement
(4) Rotation
