Constructing Plant Phylogeny Based on Morphological Characteristics and Molecular Data Phylogeny is the study of evolutionary relationships among groups of living and extinct organisms on earth (Campbell et al.‚ 2011). To show evolutionary relationships‚ a phylogenetic tree (a visual representation of the lineages among organisms) is constructed. All phylogenetic trees are hypotheses that are to be tested‚ modified‚ and tested again. One type of tree‚ known as a

How does the vascular tissue system enable leaves and roots to function together in supporting growth and development of the whole plant? 2. When you eat the following‚ what plant structure are you consuming? Brussels sprouts‚ celery sticks‚ onions‚ and carrot sticks. 3. Characterize the role of each of the three tissue systems in a leaf. 4. Describe at least three specializations in plant organs and plant cells that

Scientific Name of Plants Ornamental Perennials The following is a list of the common plant names cross referenced to the scientific name of plants. The list represents some of the most popular varieties of perennial plants. The scientific names of plants is based on taxonomy‚ the science of plant classification. Each name has two parts‚ the genus and the specie. This is referred to as the binomial (two names)system founded by Linnaeus‚ a Swedish botanist. Some species will have a third name‚

Chemical Fertilizer vs Organic Fertilizer A chemical fertilizer is defined as any inorganic material of wholly or partially synthetic origin that is added to the soil to sustain plant growth. Organic fertilizers are substances that are derived from the remains or by products of organisms which contain the essential nutrients for plant growth. Comparison chart | Chemical Fertilizer | Organic Fertilizer | NPK Ratio: | 20 to 60% | About 14% | Example: | Ammonium sulfate‚ ammonium phosphate‚ ammonium

Roots The root system of a flowering plant begins its development from the hypocotyl of the embryo of the seed which gives rise to the primary root. Roots generally grow downwards into the soil (positively geotropic) and upwards (negatively geotropic). Roots do not bear leaves and therefore no nodes are present.Two kinds of root systems can be distinguished in flowering plants: tap root systems and adventitious root systems. Usually dicotyledons posses tap root systems and monocotyledons adventitious

growth and development of Wisconsin Fast Plants Introduction It is common knowledge that plants need light to grow and develop. This is done by the conversion of light energy into usable sugars during photosynthesis. Light absorbing molecules‚ known as pigments‚ absorb only specific wavelengths of visible light‚ mostly blue and red wavelengths (1). Whatever wavelength isn’t absorbed is reflected and the reflection is the color of plant we see. Plants also respond to wavelengths of light in non-photosynthetic

Introduction: The rice plant has tillers which are a characteristic of grass plants; however they have recognized a way of growing the plant which causes it to create the best grain possible. Discussion: Vegetative: In this stage the plant germinates and gradually grows taller and leaves emerge at steady intervals. Germination: The root elongates through the seed coat and anchors into the soil. The primary leaf (coleoptile) also elongates and breaks through the seed coat. Early seedling
