Question

В чем отличие животных от растений?

Answer 1

В том, что и растения и животные – живые существа, сомнений нет. Они рождаются, развиваются, размножаются и умирают. Растения — это царство, состоящее из многоклеточных организмов. Животные представляют собой другое царство, организмы которого по способу питания являются гетеротрофными.

Растительные клетки, из которых состоит растительный организм, отличаются по строению от животных клеток, например, каждая растительная клетка окружена плотной непроницаемой оболочкой, а животная клетка – нет. Также животные в большинстве своём выделяют углекислый газ, а растения, наоборот, поглощают его, вырабатывая кислород (процесс фотосинтеза). Мы также можем сказать, что растения, в отличие от животных, не могут передвигаться. В целом это так, но мир растений настолько разнообразен, что встречаются экземпляры, которые являются исключением из этого правила. У растений есть корневая система (опять-таки, с некоторыми исключениями), у животных её нет.

Если рассматривать растения и животных с эволюционной точки зрения, то растения появились на нашей планете раньше. Сейчас на планете видов животных намного больше, чем видов растений.

Difference between Animals and Plants

Animals and plants are two distinct categories of living organisms. While they share some similarities, there are several key differences that set them apart. Here are some of the main differences between animals and plants:

1. Cellular Structure: - Animals are multicellular organisms, meaning they are composed of multiple cells. These cells are specialized for various functions and work together to support the organism's survival and growth. - Plants, on the other hand, can be either multicellular or unicellular. Most plants are multicellular, with specialized cells for different functions, such as photosynthesis, nutrient absorption, and reproduction.

2. Mode of Nutrition: - Animals are heterotrophs, which means they obtain their energy by consuming other organisms or organic matter. They are unable to produce their own food. - Plants, on the other hand, are autotrophs. They are capable of producing their own food through the process of photosynthesis, using sunlight, water, and carbon dioxide.

3. Mobility: - Animals are generally mobile and capable of moving from one place to another. They have specialized structures, such as muscles and limbs, that allow them to move and explore their environment. - Plants, on the other hand, are typically rooted in one place and are unable to move. They rely on other means, such as wind or animal pollinators, for reproduction and dispersal.

4. Reproduction: - Animals reproduce sexually, with the fusion of male and female gametes to produce offspring. They have specialized reproductive organs and undergo various stages of development, such as fertilization, gestation, and birth. - Plants have various modes of reproduction. While some plants reproduce sexually through the fusion of male and female gametes, many plants also have the ability to reproduce asexually through methods such as vegetative propagation or the production of seeds.

5. Response to Stimuli: - Animals have a well-developed nervous system that allows them to respond to external stimuli and interact with their environment. They can exhibit complex behaviors and have specialized sensory organs, such as eyes and ears. - Plants, although lacking a centralized nervous system, are capable of responding to certain stimuli, such as light and gravity. They can exhibit tropisms, which are growth responses to external stimuli, but their responses are generally slower and less complex compared to animals.

6. Structural Features: - Animals have a wide range of structural adaptations, such as limbs, wings, and specialized organs, that enable them to perform specific functions and survive in different environments. - Plants have unique structural features, such as roots, stems, leaves, and flowers, that are specialized for functions such as nutrient absorption, support, and reproduction.

It's important to note that while these differences generally hold true, there are exceptions and variations within both the animal and plant kingdoms. The world of living organisms is diverse and complex, with many unique adaptations and characteristics.
