flowering plants show sexual reproduction. A look at the diversity of structures of the inflorescences‚ flowers and floral parts‚ shows an amazing range of adaptations to ensure formation of the end products of sexual reproduction‚ the fruits and seeds. In this chapter‚ let us understand the morphology‚ structure and the processes of sexual reproduction in flowering plants (angiosperms). 2.1 FLOWER – A FASCINATING ORGAN OF ANGIOSPERMS Human beings have had an intimate relationship with flowers

supply of resources. The seeds of the water crest plants used in the following experiment‚ known as Nasturtium officinale‚ are each of the same species. Hence‚ the need of each plant for resources such as water‚ shelter‚ light and nutrients should be identical. If seedlings of the same species are planted in a controlled proximity to one another‚ the experiment is aimed to determine the extent of which intraspecific competition affects the germination of watercress seeds.

Zach Sexton December 4‚ 2014 Bot 121 Lab Coleus Lab Report 1. A cutting can form an entire new plant if cutting being used has a meristem. If the cutting has no meristem‚ mitosis will not occur and you will end up with a dead piece of plant material. In order to successfully grow a new plant through a cutting‚ your plant must have adventitious root growth which in order to deliver water and nutrients to the plant. Adventitious roots are created through cell potency where cells differentiate. The
