Mushrooms and seaweed are both increasingly popular superfoods, but they are fundamentally different. Mushrooms are fungi that grow on land, usually in dark and moist habitats such as the forest floor. They obtain nutrients by breaking down and decomposing other organisms. Seaweed, on the other hand, is a type of algae that grows underwater. While it is often categorized as a sea vegetable, seaweed is not a plant because it lacks a vascular system for transporting fluids and nutrients and has a different cell structure.

What You'll Learn
Mushrooms are fungi, seaweeds are algae
Mushrooms and seaweed share some similarities, but they are fundamentally different. Mushrooms are fungi, while seaweeds are algae. This distinction is important and places them in different biological kingdoms.
Mushrooms grow out of the soil and resemble plants, but they are not plants. They do not have "true roots", stems, or leaves, and they do not make seeds or blossoms. Instead, mushrooms produce spores. They also rely on other organisms, such as dead logs, to produce their food.
In contrast, seaweeds are photosynthetic algal organisms that can make their own food through photosynthesis. They are multicellular, marine algae that can be found in seawater or brackish water. Some seaweeds, like kelp, provide essential habitats for fisheries and other marine species.
While mushrooms exist on land, seaweeds are typically found underwater in nearshore waters, often attached to rocky substrates. Some seaweeds, like Sargassum and Gracilaria, do not attach to the sea floor and instead float freely.
Both mushrooms and seaweeds are decomposers and are considered incomplete organisms due to their lack of certain parts, such as roots. They are also both edible and used in various cuisines, although some types can be poisonous if consumed.

Mushrooms grow on land, seaweeds underwater
Mushrooms and seaweed may look similar, but they have very different characteristics and habitats. Mushrooms grow on land, often on dead logs, and are a type of fungi. They grow out of the soil and can be identified by their fibres, which can be seen under a microscope. Mushrooms do not make seeds or blossom; instead, they produce spores.
Seaweeds, on the other hand, are underwater plants, specifically, marine algae. They are photosynthetic organisms, meaning they make their own food using sunlight. Seaweeds are found in nearshore waters, often on rocky shores, and some species inhabit tidal rock pools. They can also be found floating freely in the ocean, kept afloat by pneumatocysts, or gas-filled "bubbles".
Both mushrooms and seaweeds are incomplete organisms, lacking true roots, stems, and leaves. They are also both decomposers and are edible, although some varieties are poisonous.
While mushrooms and seaweeds share some similarities, their differences are notable, particularly in their respective growing environments on land and underwater.

Mushrooms are non-vascular, seaweeds are too
Mushrooms and seaweeds are both organisms that are distinct from plants. Mushrooms are a type of fungus, whereas seaweeds are classified as algae. Despite their differences, both mushrooms and seaweeds are non-vascular.
Non-vascular plants, also known as "lower plants", are characterised by their lack of vascular tissue, which includes the xylem and phloem. These tissues are responsible for transporting water and nutrients throughout the plant. Non-vascular plants are often among the first species to colonise new and harsh environments, and they play crucial roles in their ecosystems.
Fungi, including mushrooms, form the second-largest group of organisms in the world, with approximately 1.5 million species. They are distinct from plants in that they do not have roots or leaves and do not produce seeds or flowers. Instead, mushrooms produce spores that drift around, aiding in their reproduction.
Seaweeds, on the other hand, are macroscopic, multicellular marine algae that inhabit coastal waters and the open ocean. They do not possess roots or a vascular system like land plants, but they can absorb water and nutrients directly from the ocean. Seaweeds contribute to carbon sequestration and provide habitats for many marine species.
The non-vascular nature of mushrooms and seaweeds is a result of their distinct evolutionary histories and adaptations to their respective environments. While mushrooms and seaweeds share this characteristic, they differ in other aspects, such as their reproductive strategies and ecological roles.
In summary, mushrooms and seaweeds are non-vascular organisms with unique characteristics and important roles in their ecosystems. Their non-vascular nature sets them apart from traditional vascular plants and highlights the diverse range of life forms that exist on Earth.

Mushrooms can't make food from sunlight, seaweeds can
Mushrooms and seaweed are two very different organisms. Mushrooms are fungi, and while they may grow out of the soil like plants, they do not depend on light for their nutritional needs. They lack chlorophyll, the green pigment essential for photosynthesis, which is the process by which plants convert light energy into chemical energy. Instead, mushrooms absorb nutrients from their surrounding environment, including decomposing organic matter like dead plants, wood, leaves, or animals.
However, light can still be beneficial for mushroom cultivation. While not necessary, light can improve the color, texture, and nutrient content of mushrooms. Blue light, in particular, has been shown to increase the size and weight of certain mushrooms. Additionally, light acts as a directional cue, with mushrooms growing towards the light source, a phenomenon known as phototropism.
On the other hand, seaweeds are photosynthetic algal organisms. They contain chlorophyll, which uses sunlight to make food through photosynthesis. Seaweed converts sunlight into chemical energy, forming glucose, which is the building block for their carbohydrates. This process also produces oxygen as a by-product, which is released into the atmosphere.
Seaweeds are marine algae that can be classified into three main types: Rhodophyta (red), Phaeophyta (brown), and Chlorophyta (green). They are found in coastal waters, typically at depths of 50 meters or less, and require seawater or brackish water, light for photosynthesis, and an attachment point. Some species of seaweed, such as kelp, provide essential habitats for fisheries and other marine species, while others, like planktonic algae, play a vital role in capturing carbon and producing oxygen.

Seaweeds are sea vegetables, mushrooms are not
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown), and Chlorophyta (green) macroalgae. Seaweed is classified as an algae colony, and while most seaweeds are not plants, they are photosynthetic.
Mushrooms, on the other hand, are fungi that grow out of the soil like plants. They are not plants because they do not have "true roots", stems, or leaves. Instead of making seeds, they produce spores.
Seaweeds are sea vegetables, and while mushrooms may be considered vegetables in cooking and dietary discussions, they are not sea vegetables. Seaweed is a staple ingredient in Asian cuisines, where dried seaweeds such as wakame, hijiki, kombu, and nori are used in soups, salads, grain dishes, and sushi. Seaweed is also a good source of iodine, vitamin C, iron, and calcium, and contains trace minerals such as magnesium, selenium, and zinc.
In addition to culinary uses, seaweed has various other applications. For example, it is used in the production of bio yarn (a textile), cosmetics, and paints. Seaweed farming has also been developed to improve economic conditions and reduce fishing pressure.
