Dunes

Kelp

Thallus

Kelp is the correct answer because it is a type of brown algae that is known to be the largest seaweed in the ocean. The statement provided in the question directly supports this fact, stating that the largest seaweeds in the ocean are types of brown algae. Therefore, kelp fits this description and is the correct answer.

2. The life cycle of ulvais composed of two separate stages or genations, what are those two?

Sporohyte and Gametophyte

Brown algae and kelp

Cordgrass and eelgrass

The correct answer is Sporohyte and Gametophyte. The life cycle of ulva, a type of algae, consists of two distinct stages or generations. The sporophyte stage is the diploid phase where spores are produced through meiosis. These spores then develop into the gametophyte stage, which is the haploid phase where gametes are produced through mitosis. The fusion of gametes leads to the formation of a new sporophyte, completing the life cycle.

3. Chemical in kelp that is used in foods is called ?

Agar

Algin

Gametes

Algin is the correct answer because it is a chemical found in kelp that is commonly used in the food industry. It is a natural polysaccharide that has the ability to form gels and thicken liquids, making it a useful ingredient in various food products such as ice cream, salad dressings, and sauces. Algin is extracted from kelp and has properties that improve the texture and stability of food products.

5. How are the beach plants different from the Marine algae?

Beach plants and marine algae are different in terms of their classification and structure. Beach plants are vascular plants, which means they have specialized tissues in their roots, stems, and leaves that transport food and water throughout the plant. On the other hand, marine algae are non-vascular plants, lacking these specialized tissues. This difference in structure allows beach plants to grow taller and have a more complex structure compared to marine algae, which are often smaller and simpler in form.
