Meristem cells are able to differentiate, for example, the rhizomes, leaves, flowers, fruits, and trees of plants we see are originally from the meristem, and over time, in plant hormones.
Under the influence of gravity, environmental factors, etc., the cells in the meristem begin to differentiate in all directions. The result is what we see, rhizomes, leaves, flowers, and fruits.
-
Absolutely. In general, cells that do not differentiate to the apex continue to differentiate.
-
Is your so-called meristem animal or vegetal? There is a difference, like the apical meristem of a plant, the cells in the meristem are neatly arranged and the cells are only meristems.
-
What is the concept of cell differentiation.
-
The concept of cell differentiation is as follows:Cell differentiation refers to the process in which cells with the same ** gradually produce cell groups with different morphological structures and functional characteristics.
Cell differentiation is the embodiment of the selective expression of genes, the difference between cells after cell differentiation is different from its previous state, animal cells and plant cells have cell differentiation, such as human hematopoietic stem cells, human zygotes, plant apical cells of meristem cells, cell differentiation can be found and observed.

Summary. Cell differentiation refers to the process in which the same cell gradually produces cell groups with different morphological structures and functional characteristics, and the result is that the cells are different in space, and the same cell is different from its previous state in time. The essence of cell differentiation is the selective expression of the genome in time and space, through the opening or closing of different gene expressions, and finally the production of landmark proteins.
In general, the process of cell differentiation is irreversible. However, under certain conditions, differentiated cells are also unstable, and their gene expression patterns can also change reversibly and return to their undifferentiated state, a process known as dedifferentiation.

Concept: In ontogeny, the process by which the progeny of one or one cell proliferates a stable difference in morphology, structure, and physiological function.
Characteristics: universality, persistence, stability and irreversibility. Significance: Cell differentiation is the basis of ontogeny in organisms. Cell differentiation makes the cells in multicellular organisms tend to swim in specialized liquids, which is conducive to improving the efficiency of various physiological functions.
Small cell lung cancer is the fastest growing lung cancer cell type, and it is easy to spread and metastasize, but whether it can be the best can not only depend on the cell type, but also on the morning or late of detection, whether it can be operated, the patient's physique, mentality, economic conditions, etc. In short, the combination of traditional Chinese and Western medicine will definitely achieve the best results.
There are two main differences.
First, cytoplasmic genes are passed from mother to offspring. The nuclear genes are half of the mother and half of the parents. >>>More
Stem cells are cells that are in the early stages of the body and have the potential to differentiate into multiple cells, and stem cells are very important for tissue repair and tissue regeneration. As we age, stem cells also age. Stem cell anti-aging can improve and delay aging. >>>More
Cancer cells refer to malignant tumor cells formed by normal cells that undergo genetic abnormalities under the action of various carcinogenic factors. Cancer cells** are different from normal cells, but they are fundamentally different from normal cells. First of all, normal cells are generally regular in shape and arranged in a neat arrangement. >>>More
