The type of soil- using the same type of soil will allow the plants to have no other reason to grow differently iv. How much light reaches the plant- keeping the plants in relatively the same area so that they can get approximately the same amount of light allows for accuracy as well v. Type of light- putting the plants under the same type of light, whether it be sunlight or artificial, will promote accuracy Part 2: Purpose: I want to investigate the way to keep fresh cut flowers last the longest. Research: I would research other ways that people have found out about flowers. You could find a florist's website with how to take care of fresh flowers and compare in your experiment to how a blogger says that the flowers stay fresh the longest. Hypothesis: “I believe that the florist's suggestion of using their floral conditioner will cause the flowers to last longer
Hector Finley Tue 11-2 VEGETATION ANALYSIS EXPERIMENT LAB REPORT INTRODUCTION It is predicted that different environmental conditions affect the structure of plants. Therefor the amount of sunlight that a plant is exposed too should have an effect on the plant’s structure. For example, it is said that a plant exposed to low sunlight conditions should have larger leaves then a plant exposed to high sunlight conditions. The reason behind this is that a plant with larger leaves has more surface area, therefor it would be able to make more carbohydrates from the sunlight it gathers. And thus produce more flowers and seeds than a plant with smaller leaves in the same environment.
Cell organelles are small structures within cells which carry out specialised functions and they have structures which are heavily adapted to their function. Firstly, chloroplast is a cell organelle that is commonly found in plant cells such as palisade cells and it has a unique structure which is fundamental in carrying out its function. Chloroplast is the site of photosynthesis; it carries out the light dependent reaction and the light independent reaction of photosynthesis and its structure is specially adapted for these reactions. The light dependent reaction of photosynthesis occurs in the thylakoids of the chloroplast organelle, ( which are made up to stacks of 100 called a granum) and these thylakoids provide a large surface area for the attachment of chlorophyll and the electron carriers involved in the LIR, allowing the LIR to take place. It also contains a network of proteins which holds the chlorophyll in a strict manner, allowing for maximum absorption of light and thus ensuring that enough light has been absorbed by the chlorophyll to cause excitation of electrons and for the light dependent reaction to start.
The benefits they offer are that a shoot umbrella has light aimed through the umbrella as with a softbox. While a bounce umbrella is that the light is aimed to the umbrella then bounces back towards the subject behind it. 7. Why is it important to use artificial lighting for most indoor portraits? It is important because it can create a soft light for baby pictures or different
Soil type (use one type of soil buy same type and make sure you have enough) IV. Sunlight (make sure plants are getting same amount of light put them in same spot same position) V. The pot (use same size pots same color pots) Part II: Designing an Experiment For the second part of your assignment, you get to apply the scientific method to a real life situation. Just as you saw within the lesson, the steps of the scientific method can be used to address the problem of finding the best directions to the movie theater, figuring out how to get grass to grow in your lawn, determining what color light helps plants grow fastest, or answering a variety of other questions. Think about a scenario or problem that could occur in your life in which you can apply the scientific method to answer the question or solve the problem. Explain how you would follow each step of the scientific method and design an experiment.
Photosynthetic plants in the first trophic level use energy from the Sun; these plants provide the energy for animals in higher trophic levels. In this way, energy flows through an ecosystem. Matter, on the other hand, is constantly recycled as atoms are used over and over again. Without
Part one: Katherine wants to investigate if the time of day a plant is watered affects the growth of the plant. She hypothesizes that a plant watered in the morning will grow faster than a plant watered at other times of the day. 1. Identify the specific independent and dependent variables that will be involved in an experiment to test this hypothesis. Independent: time of day the plant is watered- dependent: how much the plant grows.
Marine Science In order to test this theory we will need a list of material that will be necessary to complete this project. First i will need a plant growth light bulb and a your basic fluorescent light to see if the plant growth light bulb actually makes the plant grow faster and fuller. Secondly i will need a aquarum to test the light bulbs for that we will be using my 250 gallon aquarium and last i will need two plants to test the light bulbs on and i will be using 2 Pogostemon helferi or better know as the little star. I is a star shape plant with crinkled leaves and It grows to about 4 inches. Before i begin i decided to to a 25% water change to my tank before the test with the regular light and will also be doing this for the second
These experimental parameters were later abandoned. Identical plantings were conducted again and sunlight levels and predation via caterpillar responses were observed in laboratory conditions alongside controls to study the relationship between both variables and plant growth/survival. Data concluded that sunlight has the largest effect on the fitness of Brassica rapa and higher levels of sunlight coincided with higher levels of growth both horizontally and vertically in plant height, plant width, leaf numbers and leaf are. This research leads a much larger discussion of how plants respond to changing environmental conditions. Introduction: Plants use sunlight to separate water molecules in combination with carbon dioxide to create the sugars it uses to grow and survive and it is therefore highly important in the process of photosynthesis.
Direct sunlight should be avoided at all times. Light levels can be increased if temperatures are low, and conversely in high temperatures we recommend increased shading. Most types would be found on the forest floor, which is an indicator of the desired level of light required. POTTING MEDIA- With a few exceptions, Slipper Orchids are almost all terrestrial orchids, and enjoy constant moisture at the root zone. Therefore a potting media that holds some moisture but does not stay wet is ideal.
