According to botanists, carbohydrates are the most abundant organic compounds in plants, playing a central role in their survival. This means that to understand what is a complex carbohydrate in plants, we must look at how these intricate, long-chain sugar molecules provide both vital energy storage and crucial structural support.

Did you know that all the food we eat, whether directly or indirectly, comes from either plants or animals? This fundamental fact is key to understanding what are the sources of food for Class 7 students, and how every meal we consume fits into a larger ecosystem.

While humans and many animals rely on dietary intake for vitamins, it is a scientific misconception that all organisms require vitamins. The truth is that vitamin requirements vary dramatically across the tree of life, with many organisms capable of producing these vital compounds themselves. This fundamental difference in metabolic capability is a key distinction between different forms of life.

The human body contains over 60,000 miles of blood vessels, forming an intricate network for nutrient transport. The transport of nutrients is the process by which essential substances from food and the environment are moved to individual cells where they are needed for growth, energy, and repair. This vital biological function ensures that all living organisms, from single-celled bacteria to complex mammals, receive the necessary fuel to survive and thrive.

The chemical energy stored in glucose by plants is the fundamental energy source for nearly all life on Earth. This molecule, a simple sugar with the formula $C_6H_{12}O_6$, plays a critical role in human metabolism, but the journey from a plant to our bloodstream is a multi-step process.

In living organisms, approximately half of the energy available from glucose oxidation is captured to drive the formation of ATP, providing the primary energy currency for cellular activities. Far from being just a simple fuel, glucose is used for growth in all living organisms, from microbes to mammals and plants. This monosaccharide provides the energy and raw materials necessary for building new cells and complex biomolecules to support development, reproduction, and repair.

Over 85% of global populations may suffer from deficiencies in essential nutrients, underscoring the critical importance of a balanced diet. This deficiency can highlight the vital role of macro and microelements in supporting all life, from photosynthesis in plants to complex metabolic functions in humans.

Unlike humans and animals, most plants and microorganisms are able to synthesize all the B vitamins they need, making them an essential dietary source for human nutrition. Understanding what are the B vitamins in plants reveals their vital roles in plant metabolism and health.

Starch is the most common carbohydrate in human diets, found in staple foods like potatoes, rice, and corn. This is because plants, through the process of photosynthesis, store their excess energy as starch, a versatile and compact storage molecule.

Approximately one-third of the human diet consists of starchy foods. While animals consume these plant-based carbohydrates, a common misconception is that they also produce starch. This article will clarify whether starch is found in plants or animals and explain the critical biological differences.
