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

Experimental Design Bio 1110 ! ! Background: Plants need water to survive. Water makes up 80-95% of the mass in plant tissues. Transpiration is the loss of water from plants in vapor form. 95% of the water is absorbed from the soil for transpiration and 5% is absorbed during photosynthesis for producing necessary carbohydrates for growth. The rate of transpiration is dependent on the amount of water in which is available within the plant‚ soil‚ and on sufficient energy to vaporize water

Question 3 A nuclear power plant (NPP) make used of its nuclear power to generate electricity. The expression “nuclear power” is defined as a controlled release of energy by nuclear fission or nuclear fusion reactions (Nuclear Power‚ 2004‚ p. 2809). The world’s first exposure to nuclear power came with the detonation of two atomic bombs over the Japanese cities of Hiroshima and Nagasaki in 1945 by the army of the United State of America (Nuclear Power‚ 2004‚ p. 2809). At that time‚ scientists believed

Plant Cell Plant cells are eukaryotic cells or cells with membrane bound nucleus. Generally‚ plant cells are larger than animal cells and are mostly similar in size and are rectangular or cube shaped. Plant cells are similar to animal cells in being eukaryotic and they have similar cell organelles. What is a Plant Cell? Back to Top Plant cells are eukaryotic cells i.e.‚ the DNA in a plant cell is enclosed within the nucleus. The most important distinctive structure of plant cell is the presence

Animal cells vs. Plant cells Five Similarities Animal and plant cells have many of the same characteristic. Animal cells and plant cells are both eukaryotes. They both have cell nucleus which contain chromosomes or DNA‚ as well as cell membrane encompassing the cell to control the substances moving in and out of the cell. They both contain enzymes from liposome for breaking down larger molecules. Animal and plant cells both transport protein into and out of cells through endoplasmic reticulum

“What is a poisonous plant‚” one may ask. A poisonous plant is a something that is a toxic and can be harmful to humans‚ animals‚ and even insects. Poisonous plants exist because they may benefit a species‚ but may also be harmful to others. Many noxious plants can result in immense pain‚ sickness‚ disease‚ and mortality. Some of these plants include: the Atropa Belladonna‚ Brugmansia‚ and Ricinus Communis. The Atropa Belladonna emanates from Eurasia‚ which is located northeast of the United States

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

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
