THE BASICS OF SUPPLYING NUTRIENTS TO YOUR PLANTED AQUARIUM The environment within the aquarium and condition of the aquatic plant is not constant but changes over time. The aquatic plants will grow beautifully if you carefully select and add liquid fertilizer according to their condition. We will talk about what and when we should add to our planted aquarium in coming weeks. Part 1.

INTRODUCTION Bryophytes are non-vascular plants‚ small green‚ simple‚ spore bearing and unique among plants in having relatively large‚ photosynthetic‚ and free living haploid gametophytes‚ and unbranched diploid sporophytes that remain attached to the maternal gametophyte throughout their life span‚ thus‚ it is heteromorphic in their life cycle (Azuelo et al‚ 2012). There are about 24‚000 bryophyte species worldwide. One division is a Hepatophyta or the liverworts which are tiny
