Differentiate plants from animals based on the following: Structures. locomotion, irritability, metabolic process, waste products,growth and development, outer covering, food making process.
Physics? You have to be kidding.
sorry its biology .HEHE
There are two things in life, physics and everything else is stamp collecting.
To differentiate plants from animals based on the following factors, here are some explanations:
1. Structures:
Plants typically have a characteristic structure consisting of roots, stems, leaves, and reproductive parts like flowers and fruits. These structures allow plants to absorb water and nutrients from the soil, perform photosynthesis, and reproduce. Animals, on the other hand, have a wider variety of structures like skeletons, muscles, nervous systems, and specialized organs for digestion, respiration, and reproduction.
2. Locomotion:
Plants are generally fixed to the ground and are unable to move actively from place to place. They may show some movements in response to external stimuli, such as the movement of leaves in response to light (phototropism) or the movement of flowers to track the sun (heliotropism). In contrast, animals are capable of active locomotion, using muscles, limbs, wings, or even swimming to move around their environment.
3. Irritability:
Irritability refers to an organism's ability to respond to stimuli. While both plants and animals can respond to various external stimuli, the mechanisms and nature of their responses differ. In plants, responses are generally slower and involve growth movements or changes in biochemical processes. Animals, on the other hand, have specialized sensory organs and a nervous system that allows for rapid and complex reactions to stimuli.
4. Metabolic Process:
Plants and animals have different metabolic processes. Plants are capable of photosynthesis, a process by which they convert sunlight, water, and carbon dioxide into glucose and oxygen. This ability to produce their own food makes plants autotrophs. In contrast, animals are heterotrophs, meaning they rely on consuming other organisms (plants or other animals) for their energy needs. Animals have a different set of metabolic pathways, such as cellular respiration, to break down food and generate energy.
5. Waste Products:
Plants eliminate waste products mainly through respiration, similar to animals. However, their primary waste product is oxygen, a byproduct of photosynthesis. Animals, through various biochemical processes, produce waste products such as carbon dioxide, nitrogenous waste (e.g., urea, ammonia), and other metabolic byproducts, which are excreted through specialized organs like lungs or kidneys.
6. Growth and Development:
Both plants and animals undergo growth and development but in different ways. Plants exhibit indeterminate growth, meaning they have the ability to grow throughout their lifetime. This is made possible by the presence of meristems (regions of actively dividing cells) in specific locations, allowing for continuous growth in roots, stems, and branches. Animals, on the other hand, typically show determinate growth, where growth stops after reaching a certain size or age. Animals have a defined period of growth and development, after which they reach maturity.
7. Outer Covering:
Plants have outer coverings made primarily of a rigid material called cellulose, forming cell walls that provide structural support. This cellulose-based covering is found in stems, leaves, and roots. Animals, on the other hand, have different types of outer coverings depending on the species. Some animals have a tough outer covering like shells, exoskeletons, or skin, which serves as a protective barrier, while others have hair, fur, feathers, or scales.
8. Food Making Process:
As mentioned earlier, plants make their own food through the process of photosynthesis, utilizing sunlight, water, and carbon dioxide. This ability to synthesize organic molecules, primarily glucose, is one of the defining characteristics of plants. Animals, however, cannot synthesize their own food; they depend on consuming other organisms (plants or other animals) to obtain the necessary nutrients and energy for survival and growth.
Remember that these are general characteristics and there are exceptions and variations within both the plant and animal kingdoms.
