- Kelp, for all their outward complexity and internal structure, are not considered to possess more than one clearly defined tissue type. This being the case, they cannot be considered plants, and for this and other reasons they clearly aren't animals or fungi either.

- Classification. Seaweed is a broad term that encompasses various marine algae, while kelp is a specific type of large brown algae. Encompassing over 10,000 marine-based plant and algae species, including well-known brown seaweeds like Ascophyllum nodosum.
- Color. Seaweed typically appears in a variety of colors, including green, red, and brown, whereas kelp is mainly brown or olive-green in color. Seaweed appears in a diverse spectrum.
- Size & Growth Rate. Seaweed can vary significantly in size, from tiny microalgae to larger species. Kelp, on the other hand, is generally larger, often growing up to 150 feet in length.
- Habitat. The habitat of kelp and seaweed is a key factor that sets them apart in the underwater world. Both of these marine plants thrive in various aquatic environments, but their preferences and adaptations vary.
"Marine protists are a polyphyletic group of organisms playing major roles in the ecology and biogeochemistry of the oceans, including performing much of Earth's photosynthesis and driving the carbon, nitrogen, and silicon cycles. In addition, marine protists occupy key positions in the tree of life, including as the closest relatives of ...
Facts. Kelp can act as a powerful ocean nature-based solution to adapt and mitigate climate change. This includes through sequestering carbon that can be buried in seafloor sediments and stored for centuries. Kelp are habitat-forming species that are vital to building underwater communities and nurturing species interactions.
May 23, 2019 · The many varieties of kelp—a marine algae rather than a true plant—expand the habitat available for kelp forest residents by reaching upwards from the seafloor. Kelp species range from low-lying “bottom kelp” types or much taller species like California’s giant kelp, which can reach the surface from 80-foot depths or more.

Definition
Kelp and seaweed are both marine algaespecies, but they differ in several aspects. Seaweed is a term used to describe over 10,000 species of marine algae, including red, brown, and green varieties. These groups are distinguished by their differing light absorption rates, which influence both their color and their position in the ocean. Conversely, kelp is a specific type of seaweed that thrives in cold waters, such as the North Pacific Ocean.
Characteristics
While seaweed encompasses a vast array of different species with dramatic variation in size, kelp is consistently larger in comparison. Kelp, often also referred to as rockweed, shares more similarities with plants than other types of seaweed, and it is noted for its high calcium content. The distinct color groups of seaweed have direct effects on their ability to absorb light via photosynthesis, determining how close to the ocean’s surface they grow. Meanwhile, kelp, a type of brown seaweed,...
Uses in Gardening
1. Seaweed– Often used as a versatile fertilizer for plants, owing to its high nutrient content. 2. Kelp– Typically found in cold waters and frequently utilized as a natural supplement for its numerous health benefits. Although kelp and seaweed share some common characteristics, they are indeed different species of marine algae, each with distinct traits and applications in agriculture, health, and nutrition.
Kelp Forests
Kelp, a type of large brown algae, typically thrives in cool, relatively shallow waters close to the shore in colder seas. These aquatic plants grow in dense groupings, forming underwater forests that provide essential habitats and food sources for thousands of marine species, including fish, invertebrates, and marine mammals. Kelp forests are widespread in temperate and polar regions, with millions of people living within 50 kilometers of these vital ecosystems. Often found along rocky coast...
Seaweed Ecosystems
Seaweed, a more general term, encompasses various types of algaeincluding kelp. Seaweed ecosystems are diverse and can be found in various marine environments such as oceans, rivers, and lakes. They grow in a wide range of conditions, from shallow and cool saltwater along rocky shores to deeper and warmer waters. Some seaweeds, often referred to as sea vegetables, are even edible for humans. Seaweed ecosystems provide important habitats and food sources for numerous marine organisms. They als...
When discussing the nutritional benefits and uses of kelp and seaweed, it is essential to understand the key differences and unique properties that each type of marine plantoffers.
Kelp and seaweed have been widely used in various cuisines for their unique flavors, texture, and nutritional benefits. With their versatility in both raw and cooked forms, these marine plants have found their way into several dishes in the form of seasonings, ingredients in salads, sushi, and more.
Kelp and seaweed, both members of the marine algae family, have a significant impact on the environment and offer sustainable solutions to some pressing global issues. These aquatic plants play a crucial role in combating climate change and promoting ocean health. Research indicates that kelp, a type of macroalgae, has an impressive capacity to red...
The economic importance of seaweed and kelp has been growing steadily in recent years, with the global seaweed market experiencing rapid expansion. Seaweed farming represents a significant sector within the blue economy, providing jobs, food, and other valuable resources. Seaweed farming is the fastest-growing aquaculture sector, as noted by NOAA F...
Unlike the size of marine archaea and most marine bacteria, the cell diameter of protists ranges from less than one to several hundred micrometers (Caron et al. 2017; Finkel et al. 2009 ). Thus, it has become standard practice to group microbial eukaryotes according to a series of size fractions.
Apr 23, 2021 · Using the approach of combined DNA metabarcoding and cultivation-based surveys of 11 deep-sea regions, we show that protist communities, mostly overlooked in current deep-sea foodweb models, are...
