The discovery of a new edible plant opens fascinating opportunities in the classification and understanding of food types, particularly distinguishing whether it should be categorized as a fruit or a vegetable. Legally and botanically, a fruit develops from the flowering part of the plant and contains seeds, whereas vegetables are other parts like roots, stems, or leaves (Beveridge & Walker, 2020). If the newly discovered plant bears seeds and develops from the flowering part, it would be classified as a fruit; otherwise, it would fall under the vegetable category.

Understanding the differences between plant and animal cells reveals significant structural and functional distinctions. Plant cells possess a rigid cell wall, large central vacuole, chloroplasts for photosynthesis, and plastids like leucoplasts, whereas animal cells lack a cell wall and chloroplasts, featuring instead a more flexible plasma membrane (Taiz et al., 2015). These differences underpin the unique functions and adaptations of plant cells, such as photosynthesis and structural support.

Starch serves as a major storage carbohydrate in plants, predominantly stored in plastids called amyloplasts, mainly within the seeds, roots, and tubers of vegetables like potatoes and carrots (Gibson & Granado, 2017). This internal storage allows plants to use starch as an energy reserve, which becomes a significant dietary carbohydrate source for humans.

Among plant polysaccharides contributing to dietary fiber, cellulose, hemicellulose, and pectins are the most prominent, providing structural integrity in plant cell walls (Li et al., 2019). These components help maintain the shape and rigidity of plants, enable water retention, and affect digestibility, playing crucial roles in human health by promoting digestive health and preventing chronic diseases.

Plant pigments are classified into three main groups: chlorophylls, carotenoids, and anthocyanins. Chlorophylls (mainly a and b) are responsible for green coloration in plants; carotenoids (like beta-carotene) impart orange and yellow hues as seen in carrots and mangoes; anthocyanins produce red, purple, and blue colors found in berries, grapes, and red cabbage (Cunningham et al., 2016). Each pigment class has unique chemical structures and antioxidant properties.

Chlorophyll a differs from chlorophyll b primarily in its molecular structure, with chlorophyll a containing a methyl group and chlorophyll b having an aldehyde group. This difference affects their absorption spectra, allowing plants to optimize photosynthesis by capturing a broader range of light wavelengths (Hansson & Öquist, 2020).

Phytochemicals are bioactive compounds in plants that confer health benefits beyond basic nutrition. They have antioxidant, anti-inflammatory, and anticancer properties, which contribute to reduced risks of chronic diseases such as cardiovascular disease, cancer, and neurodegenerative disorders (Chasapis et al., 2020).

Describing the health of vegetables in the human diet to an alien involves emphasizing their rich content of essential nutrients and bioactive compounds. Vegetables offer vital vitamins, minerals, fibers, and phytochemicals that support immune function, reduce inflammation, and prevent disease, making them crucial for maintaining health (Sharma et al., 2019).

To select high-quality vegetables, factors such as freshness, firmness, vibrant color, absence of blemishes, and proper storage conditions are key indicators. For example, selecting firm carrots, ripe tomatoes, and crisp lettuce ensures maximum flavor and nutritional content (Robinson & DeLong, 2018).

Cooking vegetables induces changes in texture, flavor, color, odor, and nutritive value. Heat can soften cell walls, intensify flavors, alter pigment colors (like chlorophyll’s shift to olive green), and lead to nutrient loss (e.g., vitamin C degradation). Proper cooking methods help retain nutrients while enhancing palatability (Kumar et al., 2021).

Including legumes as a meat alternative is feasible because they are rich in protein, fiber, and essential amino acids. Their complex carbohydrates and plant-based proteins make them suitable substitutes, promoting heart health, weight management, and sustainable diets (Patel & Kumar, 2019).

The healthiest method for preparing vegetables typically involves steaming or boiling with minimal water, which preserves nutrient content and minimizes added fats. Techniques such as roasting or microwaving also retain nutrients effectively (Lee et al., 2017).

The chemical composition of fruit primarily includes sugars, acids, and phytochemicals, which influence taste qualities such as sweetness, tartness, and flavor complexity. For example, high sugar content leads to sweetness, while organic acids contribute sourness (Meyer et al., 2018).

When a banana is peeled and left exposed, enzymatic browning occurs due to oxidation of phenolic compounds by polyphenol oxidase enzymes. Preventative measures include applying lemon juice or storing in airtight conditions to slow oxidation (Khan et al., 2022).

Choosing high-quality fruits involves inspecting firmness, color vibrancy, absence of blemishes, and aroma. For example, selecting ripe apples for firmness, bright mangoes for color, and fragrant strawberries ensures optimal eating quality (Smith & Johnson, 2019).

Heating fruits leads to softening, flavor development, aroma release, and nutrient changes. For example, cooking apples enhances sweetness and texture, while vitamin C content decreases with heat (Li & Qin, 2020).

Ethylene gas is a plant hormone that promotes ripening but also accelerates spoilage in stored food. Excessive ethylene accelerates ripening and decay, leading to increased waste, particularly in climacteric fruits (Thompson, 2017).
