Morphology

The study was conducted for eight weeks to investigate the effects of 250mg/kg body weight of ethanolic leaf extract of Phyllanthus amarus on the morphology and reproductive functions of the ovary. Twenty-eight (28) adult female Wistar rats were categorized into four groups of seven rats each (n=7) with A (control), B (to assess implantation and resorption), C (to assess the litters), and D (to assess the effects on ovarian features and functions. Male adult rats of proven virility were mated with the female rats of groups B and C.

This experimental study was carried out to investigate the growth response, survival and morphology of Eichhornia crassipes (Mart.) Solms (Pontederiaceae) in crude oil polluted freshwater. The parameters measured include leaf diameter, stem girth, root length, chlorophyll content index and biomass production. The experimental treatment concentrations used were 0% (control), 1%, 2%, 3% and 4% (v/v). Using three replicates per treatment, the plants were exposed to all concentrations for eighteen days.
