Effects of Plant Nutrient Deficiency Abstract This experiment aimed to determine the effects of nutrient deficiency on plants. This was done by examining tomato plants grown in a medium that contained all the nutrients needed to survive and comparing those results to plants that were grown in nutrient deficient mediums. The biomass and standard chlorophyll content were the focus of the experiment. The biomass was measured by taking the mass of the plant. The standard chlorophyll content was

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized

Topic 9: Plant Science 9.1 Plant Structure and Growth 9.1.1 Draw and label plan diagrams to show the distribution of tissues in the stem and leaf of a dicotyledonous plant. Cross-section of a stem Part of plant | Purpose | Epidermis | Surface of the stem made of a number of layers often with a waxy cuticle to reduce water loss | Cortex Tissue | Forming a cylinder of tissue around the outer edge of the stem. Often contains cells with secondary thickening in the cell walls which provides

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others‚ where they are effective in very small amounts. Depending on the target tissue‚ a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

Polka Dot Plant (Hypoestes Sanguinolenta) also known as "freckle face" is an attractive decorative ornamental plant with velvety green leaves and splashes of color. Its color spectrum consists of red‚ white‚ purple‚ lavender‚ purple scarlet rose. The striking leaves also come in solid colors with dots. Other common names for this plant are the flamingo plant‚ the pink dot plant‚ and the measles plant suggest spotted leaves. This bushy‚ colorful plant is native to Madagascar where it can grow up

from the aerial parts of plants‚ especially leaves but also stems‚ flowers and roots. Leaf surfaces are dotted with openings called stomates that are bordered by guard cells. Collectively‚ the structures are called stomata.[1] Leaf transpiration occurs through stomata‚ and can be as a necessary "cost" associated with many processes such as the opening of the pistil and allowing the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants and enables mass flow

Transport in Plants Matthew H. 9A 131002 Today I will be discussing our experiment and the basics of transport of minerals and water in plants. Transport in plants are called transpiration. Water evaporates from the leaves which cause a type of suction that draws water from the roots. The water travels up via the vascular bundles. This flow of water is called transpiration stream. Some pressure is created forcing some water out of the cells in into the spaces between the cells

Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and

Experimental Plant Variety In order to have a suitable variety of plant types to successfully complete this experiment‚ plant types that contained recognizable traits and that would not easily be pollinated by foreign pollen were chosen. Finding a plant variety with such characteristics allowed better control over the experiment. Twenty-two varieties of pea plants were chosen by first trialing thirty-four varieties. For two years‚ only self-pollination was allowed for each of these thirty-four plant varieties

Stem Cell Research: Should we continue to allow scientists to create new embryonic stem cell lines? Good morning everyone. The topic of Stem Cell Research has been argued over by politicians‚ scientists and people all over the world for over a decade. Scientists should not be allowed to continue to create new embryonic stem cell lines. One of the ways to obtain stem cells for scientific research is to destroy a blastocyst (laboratory-fertilized human egg). Destroying the blastocyst is the equivalent
