Question

Как изменяются вещества, поступающие в растительные клетки?

Answer 1

Начнём с самого простого вещетсва. Углекислый газ при попадании в клетки растения в процессе фотосинтесса становится кислородом которым мы дышим. В зелёных частях растений так называемый хлороплст запускает процесс под названием фотосинтесс. В этом процессе вредные для человека свойства углекислого газа, ведь не зря в воздухе которым мы дышим содержится 1% углекислого газа. Тоесть растения при дыхании перерабатывают углекислый газ в кислород это дело одной секунды. А вот человек наоборот вдыхает кислород и перерабатывает его в углекислый газ. Можно сказать так человек перерабатывает кислород в углекислый газ при этом он снабжает углекислым газом растения, а растения в свой черед вдыхают углекислый газ и в процессе фотосинтеса перерабатывают его в кислород.

How do substances entering plant cells change?

When substances enter plant cells, they undergo various changes and transformations. Here is a detailed explanation of how substances change when they enter plant cells:

1. Transport through the cell wall: Substances first need to pass through the cell wall, which is a rigid layer surrounding the plant cell. The cell wall acts as a barrier and controls the movement of substances into and out of the cell. It is composed of cellulose and other polysaccharides.

2. Transport across the cell membrane: Once substances pass through the cell wall, they encounter the cell membrane, also known as the plasma membrane. The cell membrane is selectively permeable, meaning it allows certain substances to enter or leave the cell while restricting others. The transport of substances across the cell membrane can occur through various mechanisms, including passive diffusion, facilitated diffusion, and active transport.

3. Absorption and assimilation: After crossing the cell membrane, substances are absorbed into the plant cell. The absorbed substances can include water, minerals, gases (such as carbon dioxide), and organic compounds (such as sugars). These substances are then assimilated into the plant cell, meaning they are incorporated into the cell's metabolic processes and used for growth, energy production, and other cellular functions.

4. Metabolic transformations: Once inside the plant cell, substances undergo various metabolic transformations. For example, during photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. Glucose is then converted into other organic compounds, such as starch, cellulose, and proteins, which are essential for plant growth and development.

5. Storage and transport: Some substances may be stored within the plant cell for later use. For example, excess glucose produced during photosynthesis can be converted into starch and stored in specialized structures called amyloplasts. Other substances, such as water and minerals, are transported to different parts of the plant through specialized tissues like xylem and phloem.

It's important to note that the specific changes and transformations of substances in plant cells can vary depending on the type of substance, the stage of plant development, and the specific metabolic processes occurring within the cell.
