What is the Photosynthesis part labeled F?

In photosynthesis, what represents carbon dioxide?

By what letter is the oxygen represented in the diagram?

The various arrangements of leaves on the stem ensure a minimum of shading of one another and a maximum of light absorption. The structure of an individual leaf is related to the functions it carries out. There is a large surface area that allows maximum absorption of light and an open spongy network of cells that allows gaseous interchange of water, carbon dioxide, and oxygen. However, this arrangement poses a problem for the plant because the large surface area allows water to be lost by evaporation. What helps retard water loss from the leaf?




Identify the part of the plant that captures sunlight to be converted to energy via photosynthesis.

By what letter is energy represented in the diagram?

stoma) - openings in epidermis that allow gas exchange and can be closed by changes in turgor pressure in the guard cells Plants adapted to (dry) habitats often have a greater portion of their biomass allocated to belowground structures than do plants adapted to (moist) environments

By what letter is the minerals represented in the diagram?

Plant cuticleoxidized in chromium trioxide can be identified to genus and speciesthrough light microscopy and SEM, providing much greater taxonomicresolution for isotopic studies than is possible with bulk carbon andmany biomarker compounds.

What process is represented by Y?


What process is being represented in the diagram?

The process of photosynthesis transduces (converts) the kinetic energy of sunlight into the potential energy of chemical bonds. The energy is initially trapped in ATP molecules, later incorporated into the bonds of glucose, and eventually stored as carbohydrates—sugar or starch. Because this laboaratory exercise is about the Kingdom Plantae, the process of photosynthesis will be examined as it is carried out in the chloroplasts of plant cells.

What do plants release during the process of photosynthesis?

The process of photosynthesis is a complex series of chemical reactions that begins with carbon dioxide and water (molecules of low potential energy) and ends with carbohydrates such as glucose and starch (molecules of high potential energy). The metabolic activity of plants enables the radiant energy of sunlight to be transduced (converted) to the energy found in the chemical bonds of carbohydrates.

What is the name of these phenomena?

Chlorophyll, the photosynthetic pigment in chloroplasts, absorbs light energy. Plants appear green because chlorophyll does not absorb light in the yellow-green region of the visible spectrum. Yellow and green wavelengths of the spectrum are reflected or transmitted depending on the thickness of a leaf. Chlorophyll absorbs light in the blue and red regions of the spectrum. The energy absorbed by chlorophyll raises the energy level of electrons in the active center of the chlorophyll molecule. In the chloroplast, the movement of these high-energy electrons is coordinated with the formation of the high-energy molecule, ATP, and the electron carrier, NADPH. During this process, water molecules are split and oxygen gas is released. This is origin of the oxygen in the air we breathe.

What is the waste product of photosynthesis?

Photosynthesis is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy.

What is the bottom part called?

Obtain a prepared slide of the leaf cross section. First hold it against a sheet of white paper. Note that there are several slices on the slide, each of which is quite narrow (from top to bottom). Compare the thickness of the slice to the thickness of a living leaf, for example, on the plant. Then examine the slide microscopically first under low and then high power. The leaf has an upper epidermis and a lower epidermis, both covered by an outer cuticle. The cuticle is composed of a waxy substance that helps cut down on water loss from the surface of the leaf.
