为什么植物不会得癌症？

植物为什么不会得癌症是一个很好的问题！与动物不同，植物细胞有着不同的生理结构和功能，这些特点使得它们不容易受到癌症的影响。
首先，让我们了解一下癌症的本质。癌症是由体内细胞的异常增殖和不受控制的分裂引起的。这些异常细胞形成肿瘤并可以侵犯周围组织，从而对身体产生负面影响。然而，植物细胞有一些独特的特征，使它们能够有效地抵御癌症。
一个主要的原因是植物细胞具有细胞壁。细胞壁是由纤维素等复杂分子组成的坚硬外壳，它为植物细胞提供了强大的支持和保护。这种细胞壁的存在使得植物细胞相对稳定，不容易发生不受控制的细胞分裂。细胞壁还有助于阻止异常细胞的扩散，因为它们无法穿过坚固的壁。
此外，植物细胞有一个称为激素调节的独特机制。激素是一类化学物质，它们在细胞之间传递信息，并调控生长和发育过程。植物通过精确调控激素的合成和释放来保持细胞分裂的平衡。这种激素调节机制使植物细胞能够有效地控制细胞的增殖速度，从而避免癌症的发生。
另一个重要的因素是植物拥有一种叫做植物体的独特结构。植物体是由连续的器官和组织组成，它们之间紧密相连并协同工作。相比之下，动物体由离散的器官组成，这使得异常细胞更容易从一个器官传播到另一个器官。植物体的这种连续性结构有助于阻止异常细胞的扩散，减少了癌症的风险。
最后，植物拥有一套强大的免疫系统。植物免疫系统可以识别和消灭入侵的病原体，并修复受损的组织。这种免疫系统的存在使得植物能够对抗异常细胞的形成，并保持整体健康。
总的来说，植物不易得癌症的原因有：细胞壁的存在提供了强大的保护和限制异常细胞分裂的机制；激素调节有助于控制细胞增殖的平衡；植物体的连续性结构使得异常细胞难以扩散；以及强大的免疫系统可以识别和消除异常细胞。

Why don't plants get cancer?
It is a great question why plants do not get cancer! Unlike animals, plant cells have different physiological structures and functions that make them less susceptible to cancer.
Firstly, let's understand the nature of cancer. Cancer is caused by abnormal proliferation and uncontrolled division of cells in the body. These abnormal cells form tumors and can invade surrounding tissues, causing negative effects on the body. However, plant cells have some unique characteristics that enable them to effectively resist cancer.
One major reason is that plant cells have cell walls. The cell wall is a rigid outer shell composed of complex molecules such as cellulose, which provides strong support and protection to plant cells. The presence of this cell wall makes plant cells relatively stable and less prone to uncontrolled cell division. The cell wall also helps prevent the spread of abnormal cells as they cannot penetrate the sturdy wall.
In addition, plant cells have a unique mechanism called hormone regulation. Hormones are a class of chemical substances that transmit information between cells and regulate growth and development processes. Plants maintain a balance of cell division by precisely regulating the synthesis and release of hormones. This hormone regulation mechanism allows plant cells to effectively control the rate of cell proliferation, thus avoiding cancer development.
Another important factor is that plants have a unique structure called the plant body. The plant body is composed of continuous organs and tissues that are tightly connected and work in coordination. In contrast, the animal body consists of discrete organs, making it easier for abnormal cells to spread from one organ to another. The continuous structure of the plant body helps prevent the spread of abnormal cells, reducing the risk of cancer.
Lastly, plants have a powerful immune system. The plant immune system can recognize and eliminate invading pathogens and repair damaged tissues. The presence of this immune system allows plants to combat the formation of abnormal cells and maintain overall health.
In summary, the reasons why plants are less prone to cancer are: the presence of cell walls providing strong protection and mechanisms to limit abnormal cell division; hormone regulation that helps maintain a balance of cell proliferation; the continuous structure of the plant body that hinders the spread of abnormal cells; and a robust immune system capable of recognizing and eliminating abnormal cells.
