Hypogeal Germination

One of the major parts of a seed embryo is the cotyledon. Cotyledon, “usually becomes the embryonic first leaves of a seedling” (sciencedaily.com). Inside of the cotyledon is where the seed has all of its food stored. In conclusion, for germination to occur, a seed must has access to light, oxygen, water, and

Introduction: Photosynthesis is a process used by plants and specific types of bacteria in order to make their own food source from sunlight to chemical energy. It is mainly occurred within the leaves of the plant. The reaction requires light energy in order for it to be absorbed by chlorophyll. During the reaction carbon dioxide, water is converted into glucose and oxygen as shown below: Figure 1 (photosynthesis uses light energy to convert carbon dioxide into a carbohydrate) (The Chemical Equation of Photosynthesis. 2018, Accessed 16 March 2018) There are two types of photosynthetic processes; one includes oxygenic photosynthesis, which is most common and demonstrated through plants, algae and cyanobacteria while the other one is an-oxygenic photosynthesis.

Introduction/ Background Information Seed germination is the process by which a plant sprouts from a seed. Biology Discussion displayed the different steps of seed germination, and the first stage of seed germination is imbibition, which is when the seed absorbs water. This causes swelling and thus resulting in the outer coat of the seed to break and then, it will form a root. The next step in seed germination is respiration. This is when the seed takes in water and oxygen and begins to breathe and thrive (Process of).

This could have occurred from miscounting or not accurately counting the number of seeds germinated. If the experiment was completed again, more higher concentrations could be applied to the seeds to see if the data is further supported. Either way the more trials the better and more accurate results, this applies to any experiment. Practical applications of the principles of this investigation may be using the correct concentration for a specific plant or seed. This lab shows that it is necessary to follow the directions and specifications when using the fertilizer miracle

This experiment will also show if fertilizers help a plant grow more than just soil found in nature. This experiment will not try to prove if chemical fertilizer is safe or not. The chemical fertilizer being used was randomly chosen and the compost will be made from scratch. There are positive and negative effects on the plant from using both these fertilizers. The best result will be determined through daily measurements and general observations of the appearance of the

Introduction For plant reproduction to be effective, the parent plant must disperse seeds where the seed can get enough nutrients to become a mature adult plant and continue the cycle. If the parent plant can not disperse seeds away from the original source of the seed (the plant) then the seed will not stand a chance against the parent plant, in the competition for water and sunlight. Depending on the species of the parent plant, the plant may disperse seeds in one of many ways: wind dispersal, water dispersal, explosion, and animal dispersal. Water Dispersal Water dispersal is useful for plants that grow in or near water. Most of these plants, such as the Foxglove and the Harebells, have small seeds that are light enough to float on top of the water.

Without water the seeds cannot begin germinating thus the seeds in test tube N did not undergo photosynthesis(Hands On Labs). B. Were the seeds in the “G” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration? Use your results in Data Table 2 to support your answer.

Business Technology Early College High School Fertilizer Lab Experiment AP Living Environment Mr. Acquaotta/Mr. Lee Purpose The purpose that this lab was conducted was because we wanted to see if seeds germinated faster if fertilizer was applied. Introduction Fertilizer we use it when we garden, we see companies promote it in various ways, but have you ever wondered if it made a difference in growth of plants? Does it really make flowers bloom more rapidly or vegetables grow larger and more productive? The answers to these questions are all within the realm of science because they are testable by controlled experiments, observations and data gathering.

Hence, if the species of the leaf is different, the results will be inaccurate and unreliable as the rate of enzyme reaction will not be purely based on the concentration of hydrogen peroxide, but will also be dependant on the amount of substrates in the different leaves.

In conclusion, the similarities are that they all make food or energy and create sugar or use sugar. On the other hand, photosynthesis only happens in a plant cells and both cellular respiration and fermentation happen in animal and plant cells. Cellular respiration is basically the reverse of photosynthesis. Also, fermentation doesn’t need oxygen to make energy. This shows how cellular respiration, fermentation, and photosynthesis are similar and
