Plant Biology
Objectives/Goals The objective of our project is to determine which amounts of fertilizer added to Martian soil produces the most growth to bean, tomato, and carrot plants. Our goal is to ke…
Plant Biology
Objectives/Goals The objective was to determine which trees in the neighborhood are allelopathic. Methods/Materials Picked 3 different kinds of trees, chose at least one or two with little u…
Plant Biology
Objectives/Goals I wanted to see if they were certain patterns that the leaves were shaped in or if there was a characteristic difference in the leaves that defined the interior live oak. Me…
Plant Biology
Objectives/Goals The goal of this project is to discover if juices are effective in the culturing of orchid tissue cultures (meristem) when placed in pure chemical mediums. The second goal o…
Plant Biology
Objectives/Goals The goal of my project is to investigate the pitch canker pathogen in California and its specific affects, if any, on Humboldt County conifers. When directly inoculated with…
Plant Biology
Objectives/Goals My objective in this project was to determine the percentage of native and nonnative plant species in a restored area of Fairview Park. Considering how recently this project…
Plant Biology
Objectives/Goals 1 Problem Statement: Could plants survive on an ancient Mars, which is predicted to be wetter and warmer and have a denser atmosphere? Which plants were fair the best under…
Plant Biology
Objectives/Goals Plant tissue culture is a method of plant propagation in which plant tissue growth is controlled in a sterile, nutrient-rich environment. Traditionally, the nutrient media u…
Plant Biology
Objectives/Goals The objective of my experiment was to answer the following question. What happens to pollen when rain, fog, or due wets its flower? This project explores the behavior of man…
Plant Biology
Objectives/Goals The objective is to determine if precipitation and water quality effects primary productivity in the small estuaries in northern California. Methods/Materials Water quality…
Plant Biology
Objectives/Goals The purpose of this project was to determine how much salt a plant can tolerate before germination and growth are significantly inhibited; whether plants tolerate sodium chl…
Plant Biology
Objectives/Goals My objective was to study plant growth and determine if plant stems can move around obstacles toward a light source. My hypothesis was, " If plant stems can move toward a li…
Plant Biology
Objectives/Goals The objective of this project was to evaluate whether the growth of a pinto bean would be affected by different pH levels. I predict that different pH's will affect the grow…
Plant Biology
Objectives/Goals My objecive is to find which soil will germinate corn and barley seeds the fastest: sand, native Kern County soil, clay, or potting soil. I believe that native Kern County s…
Plant Biology
Objectives/Goals Local infection with a pathogen can render plants to become resistant to normally virulent pathogens. This biological response is known as systemic acquired response (SAR).…
Plant Biology
Objectives/Goals The objective of my project was to discover which color wavelength of light: red, blue, green, yellow, or white, would best stimulate chlorophyll production of oxygen. Metho…
Plant Biology
Objectives/Goals The chlorophyll concentration of Brassica rapa seeds soaked in Gibberellic Acid and untouched seeds were studied using the SPAD-502 Chlorophyll Meter#. Brassica rapa seeds w…
Plant Biology
Objectives/Goals The objective of my experiment is to determine if removing all microorganisms in a sample of potting soil through dry sterilization will have any effect on plant growth. Met…
Plant Biology
Objectives/Goals My project was to determine if Carbon dioxide affects the growth of Coleus plant growth. Methods/Materials Materials: 12 plant packs, 6 plants per pack, a total of 96 Coleus…
Plant Biology
Objectives/Goals The objective of my project was to find out which color of light plants grow best in. Methods/Materials Seven pots with bean plants were grown with six cellophane structures…
Plant Biology
Objectives/Goals The objective of my project is to determine whether different types of fertilizers promote varying growth patterns in plants. The three types of fertilizers that I used were…
Plant Biology
Objectives/Goals Radiation therapy is effective in treating cancer because the actively growing cancer cells are more sensitive to radiation than the normal tissues. Therefore, it is my hypo…
Plant Biology
Objectives/Goals The goal of my project was to investigate how wind current affects transpiration in plants. I predicted that wind will increase transpiration in geranium and cactus plants,…
