Oxygen in the chloroplasts of one plant is used by another higher animal and passes through several

14 layers, correct.

Chloroplast double membrane (O2 diffuses freely) 2 layers.

Mesophyll cell membrane (chloroplasts are mainly in photosynthetically major cell mesophyll cells) 1 layer.

Alveolar cell cell membrane (enters the lungs of higher animals and reaches the alveoli, the alveolar wall is made up of a single layer of cells) 2 layers.

The capillary wall is a single layer of cells, two layers of cell membrane (into the capillary blood around the alveoli), and 2 layers.

Erythrocyte cell membrane (into red blood cells, with which hemoglobin binds) 1 layer.

1 layer of erythrocyte cell membrane (leaving erythrocytes).

Capillary wall monolayer cells with two layers of cell membrane (into interstitial fluid) 2 layers.

Animal cell cell membrane (into animal cells) 1 layer.

First of all, chloroplasts and mitochondria are double-layer membranes, and the oxygen produced by plants passes through chloroplasts and cell membranes - 3 membranes;

Then pass through the alveolar walls of higher animals, 2 layers.

Passes through the capillary wall, 2 layers.

To the red blood cells, go to - layer 1.

The red blood cells are transported to the designated site and go out - 1 layer.

Then through the capillary wall, 2 layers.

To the tissue cell, 1 layer.

Enters the mitochondria and is utilized, 2 layers.

It adds up to 14 floors.

If you have a** unclear, please ask

Chloroplasts are double-layered membranes, and cell membranes are single-layered membranes.

Oxygen out of chloroplasts two layers, out of plant cells in one layer, in and out of higher animal alveoli two layers (into the internal environment), into the capillaries of two layers (capillaries are a layer of cells, a layer of cell membrane, from both sides through two layers is two layers), in and out of red blood cells two layers (transported by red blood cells), out of capillaries two layers, into animal cells one layer, into mitochondria two layers, a total of 14 layers.

Oxygen is produced from the chloroplasts to be used in the mitochondria of adjacent cells, and you can count how many layers of biofilm it has to pass through.

First, the tremor passes through the chloroplast 2 membranes, then through the adjacent cells each layer of cell membranes, which is also 2 layers, and then enters the mitochondria, through 2 layers. So a total of 6 layers of biofilm have passed.

Each layer of the raw mori film is composed of 2 layers of phospholipid bilayers, so the phospholipid film is 6*2=12 layers.

All chlorophyll and almost all carotenoids are embedded in the thylakoid membrane and bind to proteins in a non-covalent bond to exert photosynthesis.

So the production of oxygen must be produced inside the thylakoids, which are the chloroplast substrates.

I'm from the School of Life Sciences, and the university tutorial is very detailed, and I can take responsibility for you.

Or see: Encyclopedia - Photosynthesis Entry.

4.Analysis of the key points of photosynthesis.

Photosynthetic pigments and electron transport chain components.

Photosynthetic pigments. Second paragraph, third line.

Need. Oxygen is produced on that side of the inner capsule cavity. Not on the stromal side of chloroplasts.

From this point of view, the level of your teachers is not very good.

It is recommended that your teacher turn to the chapter on photosynthesis in the university's "Plant Physiology", take a closer look, and make up for the basic theoretical knowledge.

The Shanghai textbook is the closest to the scientific content, and the people's education version of the textbook says that on the surface, it may not be required or have low requirements for this issue.

As long as the organism is alive, whether it is day or night, it can carry out respiration, so respiration is the basic characteristic of living organisms, and the place of respiration is mitochondria, and the expression is: organic matter + oxygen carbon dioxide + water + energy, and a large amount of energy is released in the process, on the one hand, it meets its own needs, and the other part is lost in the form of heat energy In the biosphere, the respiration of green plants also consumes oxygen, which is correct

So the answer is:

7 floors. Oxygen is produced within the chloroplast film in a layer.

Oxygen comes out of the chloroplast in two layers.

Get out of the cell membrane layer.

Enter the adjacent cell membrane layer.

Enters the mitochondria for respiration in two layers.

But most of the answers in the high school biology test are 6 layers, what should I do?

You can refer to the college entrance examination questions from previous years, or high school textbooks, as for other mock questions and the like, they are of little value and have a lot of mistakes.

The oxygen produced on the thylakoid membrane of the chloroplast in a mesophyll cell of a plant needs to enter the cytoplasmic matrix through two layers of chloroplast membranes, and also needs to pass through two layers of mitochondrial membranes, so as to enter the mitochondria of the same cell, and the oxygen molecules need to pass through a total of 4 layers of biofilm Each biofilm has two layers of phospholipid molecules, that is, the number of phospholipid molecular layers that oxygen molecules need to pass through is 2 4 = 8 layers

Therefore, b

Impossible.

Various photosynthetic pigments, photosynthetic electron transport components, phosphorylation coupling factors, etc. exist in the endocyste, and the pigment is excited by light energy, electron transport, and finally ATP synthesis are carried out on the endocapsule and near its surface. The resulting NADPH and ATP are used for carbon dioxide fixation in the matrix.

Chloroplasts are organelles that convert energy into carbon dioxide and water using light energy to synthesize energy-storing organic matter and produce oxygen. Therefore, the photosynthesis of green plants is the fundamental source of the survival, reproduction and development of organisms on the earth.

The chloroplast is composed of three parts: chloroplast envelope, thylakoid, and stroma, and chloroplasts contain 3 different membranes: the outer membrane, the inner membrane, the thylakoid membrane, and 3 types of cavities that are separated from each other: the membrane space, the matrix, and the thylakoid lumen.

a) Outer cover. The chloroplast is composed of a double membrane with a 10-20 nm intermembrane space. The outer membrane is highly permeable, and many nutrient molecules in the cytoplasm, such as nucleosides, inorganic phosphorus, sucrose, etc., can freely enter the membrane space.

a. The condition of photosynthesis is light, the place is chloroplasts, photosynthesis must be carried out by living cells containing chloroplasts under light, not all living cells can carry out photosynthesis, such as root cells, a wrong;

b. Chloroplast is the main field for photosynthesis of green leaves, and there is chlorophyll in chloroplast, B is wrong;

c. Photosynthesis transforms inorganic matter into organic matter (mainly starch), which is not only used to construct the plant itself, but also provides food for other organisms and human beings**, c is correct;

d. The essence of photosynthesis is to make organic matter, release oxygen, and store energy
