Trichomes Cannabis also known as marijuana comes from the cannabis plant and is intended to be used for recreational and medical reasons. The plant has a chemical called tetrahydrocannabinol (THC) for short. (THC) has phychoactive and physiological effects in the body when consumed. When looked at under a microscope you can see trichomes on the surface of the plant. Trichomes are the physical form of (THC). “In nature‚ only the strong survive‚ and it is hypothesized by biologist that trichomes

Influence of Acidic Solutions on Lettuce Seed Germination Introduction In the environment‚ plants are critically affected by the composition of soil‚ as they acquire all nutrients from it. A nutrient must be soluble and must remain soluble long enough in order to travel into the roots of the plant (Kissel and Miller‚ 2008). Soil PH directly affects the life and growth of a plant‚ since it affects the availability of the nutrients needed for plant life. Most nutrients are in their most available

PLANT BODY Two Categories of Plant cells: 1.) Meristematic cells – embryonic‚ undifferentiated and capable of cell division • Apical meristem – located at root and shoot ends • Lateral meristem – run parallel to the long axis of roots and stems – where somatic cells undergo mitosis 2.) Differentiated/Permanent Cells – specialized in structure and usually do not divide • Simple Permanent Tissue – dermal tissue system and ground tissue system › Dermal tissue system – outer surfaces of

Germination in plants is the process in which dormant seed begins to grow and sprout under certain growing conditions. The English pea‚ also known as the garden pea‚ is a member of the legume family and is known to grow roughly three to four inches long. Research shows that it only takes approximately 1 week for the seed to start to germinate. There are many things that can affect‚ the growth of the pea seed such as; temperature‚ moisture‚ planting depth and sunlight. The pea grows best in temperatures

Michele Baden Bio 100 – 05 ALLELOPATHY INTRODUCTION The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds‚ for sunlight‚ and nutrients in order to germinate. In order to win dominance over other seeds‚ and reduce competition‚ plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants
