1.	Question : Algae are known to reproduce asexually by variety of spores under different environmental conditions. Name these spores and the conditions under which they are produced.
Answer» Solution :Algae reproduce asexually by VARIETY or spores under different environmental conditions. These spores and the conditions under which they are produced are as follow : (a) Zoospores : These are thin walled, flagellated motile spores as they are equipped with FLAGELLA. .Conditions under which it is produced : These are formed under favourable conditions and spread by wind. Aplanospores : These are thin walled nonmotile spores and lack flagella. Conditions under which it is produced : These are formed under unfavourable conditions. Hypnospore : These sporas have thick cell wall to TIDE over unfavourable conditions. Conditions under which it is produced : These are formed under unfavourable conditions. (d) Akinetes : These are formed from VEGETATIVE cells and serve as resting cells. Conditions under which it is produced : Formed under unfavourable conditions. (e) Statospore : These are similar to akinetes and are FOUND in diatoms. Conditions under which it is produced : Formed under unfavourable conditions.
