Seaweed and mushrooms are both edible and highly nutritious, with a range of vitamins and minerals. Despite their similarities, they are not plants or animals. Mushrooms are fungi, while seaweeds are algae colonies. They are both decomposers and are considered incomplete plants, lacking true roots, stems, and leaves. From a culinary perspective, seaweed is often considered a vegetable, although it is not botanically a vegetable. Seaweed and mushrooms are often used together in recipes, such as soups and salads, and their flavours are known to complement each other.

What You'll Learn
Seaweed and mushrooms are not plants or animals
Seaweed and mushrooms are often used in cooking and dietary discussions and are considered vegetables by many. However, they are not plants or animals.
Seaweeds are classified into three groups based on colour: red (Rhodophytes), green (Chlorophyta), and brown (Phaeophytes). While green seaweeds like sea lettuce are part of the plant kingdom, the other two groups are not. Brown seaweeds such as kelp and bladderwrack are in the kingdom Protista, and red seaweeds like Irish moss are currently without a kingdom based on current scientific definitions. Seaweed is a type of marine algae that grows in the ocean. It is an "incomplete plant" as it lacks true roots, stems, and leaves, which are characteristic of plants. Instead of roots, seaweeds absorb nutrients from the ocean through their surfaces.
Mushrooms, on the other hand, are classified as fungi, which are not plants. They grow out of the soil like plants, but their cellular structure is different. Under a microscope, mushrooms appear to be made of fibres, similar to cotton fibres, rather than the blocky structures seen in plants. Additionally, mushrooms do not use flowers, do not make seeds, and do not blossom. Instead, they produce spores.
Despite not being plants, seaweed and mushrooms are often considered vegetables from a culinary perspective due to their nutritional value and the ways they are used in cooking. Seaweed, for example, is often used in salads and soups, and it is rich in vitamins, minerals, and antioxidants. Mushrooms are also nutritious and can be used in various dishes, making them versatile ingredients.

They are both decomposers
Seaweed and mushrooms share several similarities, one of which is that they are both decomposers. Decomposers play a critical role in the flow of energy through an ecosystem. They break down dead organic matter into simpler inorganic materials, making nutrients available to primary producers.
Seaweeds, despite their name, are not plants but rather colonies of algae. Mushrooms, on the other hand, are fungi that grow out of the soil like plants. Both are considered incomplete plants as they lack true roots, stems, and leaves.
As decomposers, seaweeds and mushrooms break apart complex organic materials into more elementary substances, such as water and carbon dioxide, and simple compounds containing nitrogen, phosphorus, and calcium. These components are essential for the growth of other organisms, particularly plants.
In marine environments, microorganisms like bacteria and fungi initiate the decomposition process by feeding on the remains of plants, animals, and other organisms. This releases vital nutrients that are then accessible to other marine life. For example, in the ocean, decomposers like bacteria and marine worms break down dead organic matter, while detritivores like crabs and sea stars feed on the resulting detritus.
On land, mushrooms, as a type of fungi, are important decomposers, especially in forests. They break down organic matter and contribute to the recycling of nutrients, playing a crucial role in the ecosystem's health and balance.

They lack 'true roots'
Seaweed and mushrooms are both considered incomplete plants. They are similar in that they lack true roots, stems, and leaves. According to Wikipedia, a "true root" consists of a primary root and secondary or lateral roots.
While mushrooms grow out of the soil like plants, they are actually fungi. Mushrooms do not make seeds or blossoms, instead producing spores that drift around. They do not have flowers, which is another characteristic that distinguishes them from plants.
Seaweeds, on the other hand, are classified as algae colonies. They are often referred to as "sea vegetables" and used in dishes like salads and soups, but they are not true vegetables or land-based plants. Vegetables are defined as plants or parts of plants that are used as food and grow on land.
Despite not being true vegetables, seaweeds are still highly nutritious, providing vitamins, minerals, and antioxidants. They are also a good source of iodine, which is essential for thyroid function.
In summary, both seaweeds and mushrooms are decomposers and share similarities as incomplete plants, lacking true roots, stems, and leaves. However, they differ in that mushrooms are fungi, while seaweeds are algae colonies.

Seaweed is a sea vegetable
Seaweed, also known as macroalgae, is a sea vegetable that grows in oceans, rivers, and lakes. It is consumed in many parts of the world, including East Asia, Southeast Asia, and the Pacific Islands, and some traditional European societies. Seaweed is a rich source of iodine, tyrosine, calcium, and magnesium. It is also a potential vegan source of vitamin B12, although it is not considered a reliable one by the Academy of Nutrition and Dietetics. Certain types of seaweed, such as red macroalgae, are a good source of protein, minerals, and fiber.
Seaweed has numerous health benefits due to its high nutrient and mineral content. It is known to improve gut health, lower the risk of certain diseases, and protect the heart. A large study from Japan found that regular consumption of seaweed, in combination with fish and other vegetables, was associated with a reduced risk of heart disease and improved heart health. Seaweed is also rich in polysaccharides, which act like dietary fiber and promote the growth of healthy bacteria in the gut.
In the kitchen, seaweed is incredibly versatile and can be used in a variety of dishes. It can be eaten fresh, cooked, dried, or even as a supplement. Popular ways to incorporate seaweed into your diet include adding it to soups, salads, stir-fries, and sushi. Seaweed can also be sautéed, used as a seasoning, or baked into salty treats. When cooking with dried seaweed, it is important to rehydrate it first by soaking it in water for a few minutes.
Seaweed is gaining popularity in Western countries, particularly in the United States, where it is commonly associated with sushi. However, it is much more versatile than just a sushi ingredient. By exploring different types of seaweed and incorporating them into your cooking, you can take advantage of the health benefits that this sea vegetable has to offer.

Mushrooms are fungi
Seaweed and mushrooms share some similarities, including their nutritional value and the fact that they are both decomposers. However, they are also different in many ways. Seaweed is often classified as a sea vegetable, whereas mushrooms are fungi.
Mushrooms are, indeed, fungi. They are biologically distinct from plant- and animal-derived foods. They do not contain chlorophyll and cannot make their own food through photosynthesis. Instead, they rely on decaying material for sustenance. Mushrooms contain chitin, a polysaccharide derivative of glucose, which is also found in the exoskeletons of crustaceans and insects. They also contain ergosterol, a sterol not found in plants or animals.
The term "mushroom" is typically used to refer to those fungi that have a stem (stipe), a cap (pileus), and gills (lamellae) on the underside of the cap. These gills produce microscopic spores, which help the fungus spread. The standard variety is the cultivated white button mushroom, Agaricus bisporus. However, the term "mushroom" is also used more loosely to describe a variety of other gilled fungi, with or without stems.
There are around 14,000 species of mushrooms, including common varieties such as the fairy-ring mushroom, shiitake, enoki, oyster mushrooms, and fly agarics. Some mushrooms are not gilled, and may have pores, spines, or other unique characteristics. These include boletes, hedgehog mushrooms, and tooth fungi.
Mushrooms are a nutritionally unique food source, providing nutrients found in plant- and animal-derived foods, as well as having a distinct nutrient profile of their own. They are a good source of ergothioneine, a sulfur-containing amino acid with potential health benefits for humans.
