Which of the following

What happen if the electron transport system in the light dependent reaction of photosynthesis was disabled

Arada [10]

Answer: The electron transport system in the light dependent reaction of photosynthesis is the one that is responsible for the production of electrons that are used as precursor for NADPH production. ... So, if the electron transport is disabled, glucose molecule will not be produced during the dark reaction.

Observing specimens of land plants under the microscope, you see structures not found in algae. What challenge of living on land

mojhsa [17]

Answer:

Explanation:

Gravity: One of the adaptations of land plants are the deposits of lignin and cellulose. The cellular wall is composed of two phases:

- The fibrillar phase, which is inert, rigid and constituted by long cellulose molecules. Its function is to shape and protect the cell.

- The matrix, constituted by pectic and hemicellulose substances.

Other substances can compose the cellular wall. One of them is the lignin, which is one of the most important components of the secondary wall, and after the cellulose, the most abundant polymer. During lignifications, the matrix contracts because of water loss, and the spaces left by the contraction are filled with lignin. Its function is to give rigidity to the cellular wall.

Competition: The meristem is composed of non-differentiated cells, with a thin wall, abundant cytoplasm, small vacuoles, and small endoplasmic reticule. Their size and shape vary: there are small isometric cells, and long, stretched, and fusiform cells. The apical meristems are in the roots and shoots. They compose the primary plant body. During growth the meristem cells start to differentiate, allowing the plant to get bigger and higher. In the competition for light, this is very important, especially when there are too many individuals together, like in a jungle or a forest. They need to get higher to avoid being covered by other plants and to receive more radiation for photosynthesis.

Desiccation: Spores and pollen are covered by sporodermis, a membrane that covers and protects them. On the surface, there might be a pollinic cement, viscous and lipid, that favors adhesion with a pollinator. One of the principal functions of the sporodermis is to protect the spore or pollen from dehydration.

Radiation: Pigments are helpful filters; by their absorption, they protect different tissues from injurious radiation. When exposed to different radiation, it is expected a change in plant pigments. This change can be related to different seasons, different stages of the plan development and different tolerance levels. Changes in pigments reflect the structural and functional reorganization of the photosynthetic system and are an indispensable part of the process of plant hardening to the changing radiation conditions.

William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain ho

Dafna1 [17]

Answer:

Photosynthesis serves as a process of transferring carbon between the atmosphere and the biosphere by using carbon dioxide present in the atmosphere to produce sugars found in plants.

Note: The model is found in the attachment below

Explanation:

The atmosphere is the layer of gases forming an envelop around the earth. The earth's atmosphere is composed of mainly nitrogen and oxygen as well as other gases such as carbon dioxide and water vapor.

The biosphere refers to the regions of the earth's surface on which living organisms can be found. It includes the land, air and water.

Carbon dioxide is cycled between the atmosphere and the biosphere by the process of photosynthesis which is the process by which green plants manufacture their food with the aid of energy from sunlight.

From the model, in the first stage, energy of sunlight is trapped by light-dependent reactions and is used it to make ATP and NADPH. During the second stage, the light-independent reactions use ATP and NADPH reduce carbon dioxide from the atmosphere to sugars and ADP and NADP⁺.

Thus, photosynthesis serves as a process of transferring carbon between the atmosphere and the biosphere.
