The Fundamental Difference Between Plants and Animals
When you think of living things, you are probably quick to classify them as either a plant or an animal. However, have you ever stopped to think about what differentiates these two distinct forms of life? Here are some of the fundamental differences between plants and animals.
Cell Structure
One of the primary differences between plants and animals is their cell structure. Plants have a cell wall made of cellulose, while animals lack this characteristic. Additionally, plants have chloroplasts and can perform photosynthesis, which is not a capability of animals.
Mode of Nutrition
Plants and animals also differ in their mode of nutrition. Plants are autotrophs, meaning they can make their food from sunlight, carbon dioxide, and water. On the other hand, animals are heterotrophs that require organic compounds obtained from other organisms to survive.
Body Structure
The body structures of plants and animals are also remarkably different. Plants typically have rigid structures and remain fixed in one location, with roots growing downwards into the soil and shoots growing upwards towards sunlight. In contrast, animals tend to be mobile, have a more complex structure, and exhibit different bodily functions, such as digestion, respiration, and circulation.
Reproduction
Finally, plants and animals differ in their methods of reproduction. Plants employ asexual reproduction, whereby they produce offspring without the need for a mate. Alternatively, they can reproduce sexually, which involves the transfer of pollen from one plant to another. Animals, on the other hand, reproduce sexually, where the male sperm fertilizes the female egg, leading to the development of offspring.
In conclusion, plants and animals are two different forms of life that differ significantly in their cells’ characteristics, mode of nutrition, body structures, and methods of reproduction. Understanding these differences is essential in developing an appreciation for the incredible diversity of life on our planet.
Table difference between plant and animal
| Category | Plant | Animal |
|---|---|---|
| Structures | Have cell walls made of cellulose | Do not have cell walls |
| Photosynthesis | Capable of producing their own food through photosynthesis | Cannot produce their own food |
| Movement | Do not exhibit any form of movement | Capable of movement using various body parts |
| Reproduction | Reproduce sexually and asexually | Reproduce sexually and give birth to live young or lay eggs |
| Examples | Flowers, Trees, Shrubs | Dogs, Cats, Birds |
