Exception- Cephaleuros (a parasitic algae) Fresh water or marine Thallus body Reserve food material is starch Cell wall- cellulose True parenchymatous cells are present Nonflowering Microscopic or macroscopic Reproduction- vegetative, asexual and sexual Eg. Spirogyra, Volvox, Chlamydomonas, Chara etc   a.  Chlamydomonas b.  Spirogyra c.  Volvox Q and A of Algae Distinguish between coenocyte and coenobium. (1) Coenocyte Coenobium 1. A mass of cytoplasm surrounding many nuclei and enclosed by a cell wall. It is found in certain algae and fungi. 1. A colony of Volvox is called coenobium. Mention few characteristics of (unicellular) Chlamydomonas. Ans. a. Chlamydomonas is a unicellular motile green alga possessing two flagella and usually a cup shaped chloroplast. b.

Classification of Plant Kingdom

Hi viewers: In this blog Classification of Plant Kingdom we will discuss the classification of Plants on the basis of different item. Classification of Plant Kingdom Hi viewers, today we will discuss about the Classification of Plant Kingdom.  The plant kingdom is broadly classified into a) Cryptogam and b) Phanerogam.  The word ''Crypto'' means hidden and the word ''gam'' means flower.  So all the bacteria, algae, fungi, bryophytes and pteridophytes are clubbed under Cryoptogams where flowers are not seen.  And all the Gymnosperms and angiosperms are clubbed under Phanerogams where flowers can be seen. Virus an enigma between living and nonliving Schizophyta- Bacteria Thallophyta- Algae and Fungi Bryophyta- Moss Pterydophyta- Fern Gymnosperm- Cycas and Pinus Monocotyledonous- All the pulses and cereals Dicotyledonous- All the flowering plants Virus an enigma between living and nonliving     PROPERTIES OF VIRUS   It is the bridge between living and non-living It is living when it is present inside the body of the host and non-living when it is outside the body...
