Photosynthesis is the transformation of sun energy into chemical energy, which plant can actually use. Only plants, or autotrophs, can do this. Autotrophs are simply organisms that can produce their own food. They harness their energy form the sun to carry out photosynthesis (Miller and Levine) However, other things are needed to do photosynthesis as well. Carbon dioxide and water are the key components to process photosynthesis. Chloroplast makes photosynthesis happen. They are organelle, or a specialized structure that performs important task in the plant cell.

(Bailey, 2001). Since a seed cannot grow with the aid of photosynthesis, it must first grow with the help of a process called respiration. Water is necessary to perform respiration. The water enters the plant through tube micropyle, a microscopic pore n the pollen entered the ovule of the plant. (Bailey, 2001) Water will soften the seed coat which makes it easier for the first root to escape the seed casing and plant itself to the ground. On the tip of the radicle is a dense mat of root hairs that collect more water to the plants. Shortly after that, the rapidly dividing cells called meristems produce the first shoot that emerges from the seed. It is very delicate, needs to be protected by a cylindrical sheath that helps sunflowers to push through the soil particles much easier (Bailey, 2001). After the seed emerges the sheath that has protected those for days will become the plants first shoots or …show more content…
The pH scale ranges from 0 to 14. On the pH scale, a pH of 7 is neutral, 0 to 7 is acidic, and 7 to 14 is basic. While growing plants, the preferred pH level of soil is 6.5 (Miller, 2001). Pure water is generally neutral with pH of 7. When chemicals are mixed with water pH can be changed to become more acidic or basic. Some common liquids have different pH value than water includes vinegar, wine lemon juice, beer, tomato juice, milk and sea water. Vinegar has pH of 3, wine has pH of 2.8 to 3.8, lemon juice has pH of 2.5, beer has pH of 4 to 5, tomato juice has pH of 4 and milk has pH of 6.3 to 6.6, and sea water has pH of

Red Alder Vs Douglass-Fir Essay
682 Words | 3 PagesDouglas-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.

The light reactions convert light into energy (ATP and NADHP) Occurs in thylakoid stacks of grana Sunlight is converted into ATP (free energy containing molecule) and NADPH (high energy electron carrying molecule) Chlorophyll absorbs light energy and starts a chain of
Belonging To The Plantae Kingdom
1360 Words | 6 PagesThese complex organisms consist of two organ systems, the root system and the shoot system. The shoot system is an above ground organelle system, this is where the leaves, stems, buds, flowers (depending on the plant) and fruits (depending on the plant) are found. Thus, therefore, meaning that the root system is the below ground system and includes the roots, rhizomes and tubers. There are three types of plant cells which are formed in the meristem (tissue in most plants that contain undifferentiated cells, the cells produced here help various organs of the plant and help with the growth of the plant.) The first plant tissue grouping is Dermal, the Dermal system looks after the covering of the plant, and can be broken down into many subsystems.

1104 Words | 5 PagesThe amount of water the plants need every day for their daily activities such as for growth and photosynthesis is small when compared to what is really lost because of transpiration. Plants have specialized pores called stomata which are in charge for allowing the passing of materials. The stomata pores are surrounded by cells called guard cells whose function is to expand and contract so that they can open and close the stomata. So for example when the plant is losing too much water the guard cells close to stop that.
Germinated Seeds In The Dark Essay
387 Words | 2 PagesWe accept our hypothesis of the germinated seeds in the dark and the dormant seeds in the dark having a higher rate of cellular respiration then germinated seeds in the light and the dormant seeds in the light. The germinated seeds in the dark had 0mL of change in oxygen levels while the germinated seeds in the light had -.05mL of change in their oxygen levels. The germinated seeds in the dark had a .05mL more for their change in oxygen then the germinated seeds in the light, therefore the germinated seeds in the dark had a higher rate of cellular respiration then the germinated seeds in the light. The dormant seeds in the dark had 0mL of change in their oxygen levels and the dormant seeds in the light had -.16mL of change in their oxygen levels. The dormant seeds in the dark had a .16mL greater change in their

Spinach Leaf Photosynthesis Lab Report
1169 Words | 5 PagesThe process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.

The average for pH paper was seven. The pH is the numeric scale used to specify the acidity or alkalinity of an aqueous solution. The pH scale measures acidity and alkalinity. the pH scale goes from zero, which is an acid reading, to fourteen, which is an alkaline reading.

609 Words | 3 PagesThis 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
Spinach Lab Report
547 Words | 3 PagesPhotosynthesis takes place in the chloroplasts; green organelles inside plant cells. The thylakoid inside Chloroplasts absorb the sunlight energy needed for photosynthesis. The pigment in the thylakoid absorbs light; however, plants reflect green light. This gives plants their color. If different colors of light are shown on spinach leaves and CO2 consumption is measured, then the spinach leaves given green light will consume the least amount of CO2 due to reduced photosynthesis activity.
Compare And Contrast Cellular Respiration And Photosynthesis
420 Words | 2 Pagesphotosynthesis 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.
