The biosphere is composed of soil, the atmosphere, plants, and animals. Among which the plants and animals are the most important component.
As we know, humans are the most intelligent creature. There are many differences between the plant and animal kingdoms.
When considering mainly the difference between plants and humans. They have many more huge differences between them.
So here are some differences between plants and humans.
Key Takeaways
- Plants are autotrophic organisms that produce their food, while humans are heterotrophic organisms that consume other organisms for food.
- Plants have cell walls and chloroplasts, while humans do not.
- Plants respire through tiny openings called stomata, while humans respire through lungs.
Plants vs Humans
Plants are living organisms that rely on sunlight and water as a source of food, but they are normally stationary beings that can move around. Humans are living creatures that keep growing until a certain age and then die, but they are mobile and can perform different activities while alive.
The plants belong to the kingdom Plantae. Plants are of a wide range variety.
Starting from algae to the big old banyan tree, all plant varieties are available worldwide. Plants are mainly autotrophic in the mode of nutrition.
They can prepare their own food using sunlight, chlorophyll, and other raw materials. The humans belong to the kingdom Animalia.
They belong to the heterotrophic mode of nutrition. That is, they cannot prepare their own food.
Humans have more advanced senses than plants. Humans have special tissues that secrete special chemicals which lead to feelings and emotions in humans.
Comparison Table
| Parameters of Comparison | Plants | Humans |
|---|---|---|
| Mobility | Plants are stationary organisms, and they can’t move | These are mobile creatures, and they can move around and have the ability to adapt themselves to the environment. |
| Growth | They can grow throughout their lifetime | They can grow till a certain age in their lifetime |
| Vacuoles | Present at large numbers | Absent |
| Kingdom | Plantae | Animalia |
| Mode of nutrition | They have an autotrophic mode of nutrition | They have a heterotrophic mode of nutrition |
What are Plants?
The plants belong to the kingdom Plantae. Plants are of a wide range variety. Starting from algae to the big old banyan tree, all varieties of plants are available around the world.
Plants are mainly autotrophic in the mode of nutrition. They can prepare their own food using sunlight, chlorophyll, and other raw materials.
The body structure is also different. The cell in plants has cell wall in them.
This cell wall provides a rigid shape and, thus, a rigid body to them. The cells are rectangular in shape. Plants have many vacuoles, which are used for respiration and other uses.
Plants have a pigment called chlorophyll which makes them green and helps them to make their food. These are found in chloroplast cells.
The process of preparing food in plants is called photosynthesis. The food prepared is distributed throughout the body through a pipeline system.
Plants have the ability to grow till they die. They have a very simple transportation system in their body.
Plants produce oxygen and absorb carbon dioxide, which is a very important conversion for the earth. This makes the plants called the lungs of the earth.
Plants can reproduce in both asexual and sexual modes. The asexual mode of reproduction is vegetative propagation, and the sexual mode is pollination.
There are two different kinds of plants, dicotyledonous and monocotyledonous plants.
What are Humans?
The humans belong to the kingdom Animalia. They belong to the heterotrophic mode of nutrition, and they cannot prepare their own food.
Humans have more advanced senses than plants. Humans have special tissues that secrete special chemicals which lead to feelings and emotions in humans.
Humans exhibit the heterotrophy mode of nutrition. They depend on other animals and plants for their food.
They cannot prepare their own food, while humans have the ability to move, they are called mobile. Humans belong to the omnivore category.
Humans have different body structures than plants. The cells of humans are not in a particular shape.
The different cells have different shapes according to their functions. Human cells do not have cell walls in them.
Humans have a red pigment called haemoglobin that gives the red colour in the blood. The main transportation of nutrients and minerals in the body is by the blood.
Humans have different systems formed by different organs with specified functions. Humans also have advanced sensing.
There are different chemicals in the body secreted and thus forming different emotions in humans. The main master of the body is the brain.
This brain differentiates humans from other creatures.
Main Differences Between Plants and Humans
- Plants are stationary. They cannot move around. On the other hand, humans are mobile. They can move around. Humans have the capacity to adapt themselves to the environment in which they are surviving.
- Plants can grow throughout their lifetime, but humans can grow up to a certain age.
- Vacuoles are present in large numbers in plants but absent in humans.
- All plants belong to the kingdom Plantae. On the other hand, all animals, including humans, belong to the kingdom Animalia.
- Plants possess an autotrophic mode of nutrition, meaning they can prepare their own food from the simple raw substances available in nature.
- In contrast, humans have a heterotrophic mode of nutrition which means that they cannot prepare their own food and are dependent on other plants and animals for food.
