Seed type and cellular respiration All cells perform cellular respiration to maintain homeostasis and growth. Plants can produce sugar from suns energy, when they need energy they metabolize stored sugars through cell respiration. Plants need the energy to perform different task such as transportation or growth. Similarly to human cell respiration, cellular respiration rate in plants isn’t always consistent and depends on many other factors. After a seed is dropped from plant it goes into a resting period (dormacy) where the stored energy is released very slowly. As their survival depends on it seeds, seeds can detect the quality of light or composition of light. Some seeds have to wait for a long period of time before they are able to germinate, during this time period they are not able to nurture itself because of the lack of leaves. For the seed to stay alive and grow during that time it has to use stored energy reserves and undergo cellular respiration. Seed suppliers measure cellular respiration rate to determine if dormant seeds are still viable and can be used for cultivation. When plants use sugars stored in their leaves or seeds they undergo cellular respiration. Sugar + Oxygen Carbon dioxide + Water + Energy (ATP) …show more content…

I will place the seeds into tubes that contain calcium hydroxide, and invert them in to beakers with water right after. Calcium hydroxide will react with carbon dioxide that is produced and remove the gas from the test tube air space. As seeds are respiring they are absorbing oxygen and respiring carbon dioxide, but the carbon dioxide is absorbed by the calcium hydroxide. As a result of these reactions the air in these tubes decreases and the water increases. This shows us a visible indication of occurring

Red Alder Vs Douglass-Fir Essay

682 Words | 3 Pages

Douglas-fir and red alder have seeds that use wings, signifying the use of the wind as a method of seed dispersal. Both trees have seeds than are covered in a seed coat and have nutrient reserves. Gymnosperms, however, have a large megagametophye, which is the haploid nutritional tissue. Angiosperms typically have a smaller megagametophye, that later develops into an endosperm (red alder, however, does not have an endosperm). When seeds germinate, general 4 steps usually occur first: 1) Imbibition, when seeds swells with water and the seed coat ruptures 2) Metabolism increases.

Mitochondria Lab Report

737 Words | 3 Pages

During this experiment, mitochondria were isolated from 20.2 grams of cauliflower using extraction buffer, filtration through Miracloth, and centrifusion. Twelve samples containing various volumes of mitochondrial suspension, assay buffer, DCIP, sodium azide, and citric acid cycle intermediates were prepared to be read by a spectrophotometer. The inclusion of the dye DCIP allowed for the absorbance of the reactions between the mitochondrial suspension and the TCA cycle intermediates succinate, malonate, and oxalate to be measured, as DCIP turns from blue to colorless as the activity of succinate dehydrogenase increases. Experimental Findings Increasing the number of mitochondria in the reaction did increase the reduction of DCIP relative to the amount of mitochondrial suspension present.

In this experiment, scientists, Emily Yau and Mona Howell, conducted an experiment that tested how acidity and radiation affects germination of radish seeds. ​We had hypothesized the seeds that microwave for 5, 10, and some of the 15 second seeds will grow. The radish seeds in the 1 and 2 teaspoons will sprout. We should accept our hypothesis because in the most part, it was correct. Although most of our data supports our hypothesis, some of our data contradicts our hypothesis.

Biology: Photosynthesis And Respiration

593 Words | 3 Pages

As stated in the background of the lab, "seeds are considered to be in a period of dormancy, where they metabolize stored energy at a very slow rate while the seed is still considered alive" (Hands On Labs). During germination, the developing plant embryo uses the stored food supply in the seed for cellular energy and growth. Thus, cellular respiration is taking place as the seeds grow. 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?

Compare And Contrast Cellular Respiration And Photosynthesis

420 Words | 2 Pages

photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.

Abstract The purpose of this experiment is to test for mitochondrial activity by isolating different organelles using the differential centrifugation process. Studying mitochondria is extremely important because they control the death and life of the cell by regulating the apoptotic signals (Frezza et al 2007). Also they are responsible for the metabolic reactions (aerobic respiration) and the production of ATP (Frezza et al 2007). Three hypotheses were formed based on my knowledge.

Its carbohydrate content, unlike other type, converts to maltose making digestion easier. The sprouting process A seed turning into a plant is a compound process involving proteins, enzymes and genes. It begins once the seed breaks through its shell, digs into the earth and then bears a small, tender tangle. With all the right elements present and a friendly surrounding, this sprout develops into a plant.

Dependent Variable Rate of Respiration (Rate of which CO2 is produced in ppm/s) The rate of respiration of the germinating seeds can be represented by the rate of which CO2 is produced. The rate of respiration is expected to be affected by the change in temperature of the environment. As mentioned in the hypothesis, the change in the respiration rate is most likely to be due to the involvement of enzymes in the process.

This is very similar and related to the previously discussed objective of being able to identify biological processes that require energy. Modeling the way organisms capture and store free energy was achieved in several different labs, including the cellular respiration lab. In the lab, we modeled how an organism can capture and use energy through facilitating the germination of seeds. Germination is a very complex biological process that requires the capture and storage of energy for later use. Modeling this process allows further investigation and greater understanding of how energy is captured and used by

Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.

A seed is, ”a flowering plant 's unit of reproduction, capable of developing into another such plant” (dictionary.com). Germination is, “the stage in which a germ or a living thing starts to sprout, grow and develop” (biology-online.org). A cotyledon is, “the primary or rudimentary leaf of the embryo of a seed plant that either remains in the seed or emerges upon seed germination; a modified leaf that is part of the plant embryo within the seed; a seed leaf” (biology-online.org). Many things go into triggering germination such as nutrients, and some non-nutrient chemicals. One can tell when germination ends by observing the shoot breaking through the soil.

This is vital so that the plant can live and take in carbon dioxide and produce oxygen. According to NCS Pearson, many things can affect the germination period, such as temperature, soil, and light (Factors). However, does the age of the seed affect the germination period? In this experiment, a total of six pots were used, three had seeds that were six years old and three had seeds that were only one year old, and throughout the course of fifteen days, the plants were closely monitored to determine how quickly and how many seeds grew. The purpose of this lab is to determine if the age of a seed affects the germination rate.
