What is the symbiotis relationship between Brittle Star and Kelp Holdfast?
The brittle star and kelp holdfast engage in a symbiotic relationship where the brittle star benefits from the protection and habitat provided by the kelp's holdfast. The holdfast anchors the kelp to the substrate, creating a stable environment that offers shelter and a place for the brittle star to hide from predators. In return, the brittle star can help the kelp by feeding on detritus and small organisms that may harm the kelp, contributing to a healthier ecosystem. This interaction exemplifies the mutual benefits and interconnectedness of marine organisms.
How long kelp root?
Kelp does not have traditional roots like terrestrial plants; instead, it has a structure called a holdfast that anchors it to the ocean floor. The holdfast can vary in size but typically measures a few inches across. Kelp can grow rapidly, often reaching lengths of up to 100 feet or more, but the holdfast itself primarily serves to secure the kelp rather than absorb nutrients like roots do in land plants.
What is the topographic features of kelp forests?
The holdfast The correct answer is that that the Top Layer is called a Canopy, the middle and the floor
Do most kelp move place to place?
No, most kelp species are attached to the seafloor by a holdfast and do not move from place to place. They rely on water currents to bring nutrients to them. However, some species of kelp have gas bladders that help them float, allowing them to drift with the currents.
How Much kelp do sea urchins eat?
yes
How does kelp get water in the ocean?
Kelp absorbs water directly through its fronds and the surface of its holdfast, which is the root-like structure that anchors it to the ocean floor. Unlike terrestrial plants, kelp does not have specialized roots for water uptake; instead, it relies on diffusion to take in seawater and the nutrients dissolved in it. This allows kelp to thrive in nutrient-rich coastal waters, where sunlight and water conditions are favorable for its growth.
What are adaptations of Giant kelp?
All organisms have all kinds of adaptations. If giant kelp have chloropasts, then giant kelp can receive its energy and nutrients from sunlight. This photosynthesis helps the kelp survive. Another adaptation of giant kelp could be having a holdfast, which keeps it anchored to the seafloor, preventing the kelp from drifting away from kelp forests.
Where do kelp live?
Kelp live the the sea. You will not be able to see them because they are very small. ADDED: ??? Oh yes you can see it! Kelp is a large sea-weed with characteristically long, flat fronds narrowing down to a rubbery stem above its holdfast. It does not live "near" the sea but in it - growing prolifically in shallow waters usually fairly close inshore.
What is the shape of kelp?
Kelp typically has a long, slender, and flexible body that can resemble a series of flat, ribbon-like fronds. The fronds can vary in width and may have a wavy or smooth texture, often extending from a central holdfast that anchors them to the ocean floor. Overall, kelp can create a dense underwater forest, with its structure providing habitat for various marine life.
Why is kelp not a plant?
Answer Kelp belongs to the kingdom Chromista. Plants are photosynthetic and store energy in the form of starch. Kelp are also photosynthetic, but produce sugars and not starch. Also, kelp and other chromists have "chlorophyll c" which gives it he characteristic brownish tint. This pigment and others that chromists contain are not found in any "plant." ChromistaThe kingdom Protista has been divided into Chromista and "other protists" The chromista have closer evolutionary ties to plants, animals, and fungi than they do to other protists. They are eukaryotic and autotrophic. This group includes red/brown algae (kelp) and diatoms. The multicellular organisms in Chromista are thought to have evolved their multicellularity independently from other kingdoms. Chromo means color, and although some chromists are colorless, they are characterized by a yellowish/brownish color coming from their version of chlorophyll. Anatomy of Kelp The features of kelp look like plant features. Where a plant would have roots, kelp has a "holdfast". The purpose of the holdfast is to attach the kelp to the sea floor. It does not obtain nutrients in the way that plant roots do. The "stipe" or stalk of the kelp is analogous to the stem of plants. The blades of kelp are analogous to leaves. In some kelp, at the base of the kelp blades, there are structures called gas bladders that allow the kelp to float upright.
How does the kelp use its structure to survive?
Kelp has a unique structure that allows it to thrive in marine environments. Its long, flexible blades can sway with ocean currents, reducing the risk of damage from strong waves. The gas-filled bladders, or pneumatocysts, help keep the kelp buoyant, allowing it to reach sunlight for photosynthesis. Additionally, its root-like holdfast anchors it to the ocean floor, providing stability and access to nutrients.
Why isn't a large piece of kelp considered a plant?
