The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period

Romeo and Juliet Extract Commentary The extract is situated near the starting of the bonding between Romeo and Juliet. The main purpose of the extract is to show the stupidity of the feud between the Capulets and the Montagues. This scene also where the relationship between Romeo and Juliet starts becoming unbreakable as they make decisions without any real thought. The scene is situated after the ball at the Capulet’s Orchard‚ near Juliet’s balcony. Shakespeare uses both structure and language

MAKES VINCA PLANTS GROW THE BEST? My Science Experiment! The experiment is to take 4 Vinca plants‚ which are about the same size‚ health‚ and flowering stages and find out which one will grow the best. Each of the plants will have 75 ml of a liquid daily for 10 days. My Grandma bought them from Lowes on September 20‚ 2011 for me. Breakdown of the plants are as follows: Control plant will get tap water. Plant A will get Milk from the refrigerator. Plant B will get

are more to aquatic plants than just floating on the surface of water. Aquatic plants are plants that can adapt and live in a freshwater environment. They are sometimes called hydrophytes. These include plants that live in fresh wetlands‚ swamps‚ ponds‚ lakes‚ and marshes. This type of plant actually serves two important functions. First‚ they help oxygenate water (2006) and they provide nutrients and food for some fishes (Tappin‚ 2003). There are many types of aquatic plants including rooted‚ emergent

Danielle Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs

PLANT RESPONSES TROPISM is a biological phenomenon‚ indicating growth or turning movement of a biological organism‚ usually a plant‚ in response to an environmental stimulus. In tropisms‚ this response is dependent on the direction of the species. The word tropism comes from the Greek trope ("to turn" or "to change"). Tropisms are usually named for the stimulus involved and may be either positive (towards the stimulus) or negative (away from the stimulus). Phototropism is the growth response
