“Alga is a term that describes a large and incredibly diverse group of eukaryotic, photosynthetic lifeforms. These organisms do not share a common ancestor and hence, are not related to each other (polyphyletic).” Multicellular examples of algae include the giant kelp and brown algae.
Jun 2, 2024 · Algae are a type of aquatic plant that contains chlorophyll and can carry out photosynthesis. They are similar to plants in that they are autotrophs, but they are not structurally similar to plants in their external appearance. Algae can be classified as red algae, green algae, or brown algae.

Algae are polyphyletic photosynthetic eukaryotes, which are microscopic as well as macroscopic thallophytes lacking any sterile covering of cells around reproductive organs and contain chlorophyll-a as a primary photosynthetic pigment. They occur in wetlands as both phytoplankton and periphyton.
Red algae or Rhodophyta are one of the oldest groups of eukaryotic algae. They are red in colour because of the presence of a red coloured pigment called Phycoerythrin.
Algae are morphologically simple, chlorophyll-containing organisms that range from microscopic and unicellular (single-celled) to very large and multicellular. The algal body is relatively undifferentiated and there are no true roots or leaves.
5 Main Types of Algae in the Ocean. Algae absorb 45-50% of global CO2 and are key to the environment. Explore the 5 main types of algae: Brown, Green, Red, Diatoms, Dinoflagellates. Algae, often overlooked and underestimated, are foundational organisms in marine ecosystems.
Oct 4, 2021 · Algae are photosynthetic eukaryotic organisms, belonging to the Protista kingdom. They are predominantly aquatic, although they are also found in other environments. They can be single...
Algae is the plural form of the word alga, which denotes a single algal organism. Algae species range in size and composition from the tiny single-celled Micromonas to the giant multicellular sea kelps that aggregate into the underwater kelp forests found along continental coastlines.
Jun 4, 2023 · In this article, we will explore the intricate process of algae growth, examining the factors that influence their development, their reproductive strategies, different growth forms and structures, their habitats, and the diverse applications they offer.
