Difference between animal and plant kingdom?

Question

Answer

Animal kingdom -

. Absence of cell wall

. Mode of nutrition is heterotrophic

. They are consumers

. They do not contain chlorophyll

. They can move from place to place

Plant kingdom -

. They have a cell wall

. Mode of nutrition is autotrophic

. They are producers

. They contain a green pigment called chlorophyll

. They are immobile and cannot move from one place to another

Answer

Key Difference: Plants are multicellular eukaryotes that belong to the kingdom, Plantae. Green plants have cellulose cell walls and obtain much of their energy from sunlight through the process of photosynthesis. Animals are multicellular, eukaryotic organisms that belong to the kingdom, Animalia.

Answer

Difference between Animal and Plant Kingdom

Introduction:
The animal and plant kingdoms are two major classifications within the domain of living organisms. Both kingdoms represent different groups of organisms that possess distinct characteristics and functions. Understanding the differences between these two kingdoms is essential in order to grasp the diversity and complexity of life on Earth.

Key Differences:

1. Cell Structure:
- Animals are multicellular organisms composed of eukaryotic cells, meaning their cells contain a nucleus and membrane-bound organelles.
- Plants are also multicellular, but they have cell walls made of cellulose and possess chloroplasts, which are responsible for photosynthesis.

2. Nutrition:
- Animals are heterotrophic organisms, meaning they are unable to produce their own food. They obtain nutrition by consuming other organisms or organic matter.
- Plants are autotrophic organisms that produce their own food through the process of photosynthesis. They use sunlight, water, and carbon dioxide to synthesize glucose and release oxygen as a byproduct.

3. Mobility:
- Most animals are capable of movement, either through the use of limbs, wings, or specialized structures.
- Plants, on the other hand, are generally sessile and unable to move from one place to another. However, some plants exhibit minimal movement in response to stimuli, such as the movement of leaves or flowers.

4. Reproduction:
- Animals reproduce sexually, with the fusion of male and female gametes. They exhibit a wide range of reproductive strategies, including internal and external fertilization.
- Plants have various modes of reproduction, including sexual and asexual methods. They can reproduce through the fusion of male and female gametes or through vegetative propagation, such as the growth of new plants from stems, leaves, or roots.

5. Respiration:
- Animals generally respire through specialized respiratory organs such as lungs, gills, or tracheal systems. They exchange gases with their environment to obtain oxygen and release carbon dioxide.
- Plants respire through tiny openings called stomata present on their leaves and stems. They take in carbon dioxide and release oxygen during respiration.

Conclusion:
The animal and plant kingdoms exhibit fundamental differences in terms of cell structure, nutrition, mobility, reproduction, and respiration. While animals are heterotrophic, mobile, and rely on other organisms for food, plants are autotrophic, generally sessile, and produce their own food through photosynthesis. Understanding these distinctions allows us to appreciate the diversity and uniqueness of each kingdom and their contributions to the overall ecosystem.
