2024年12月17日 · algae, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista. Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length.

Algae (UK: / ˈ æ l ɡ iː / AL-ghee, US: / ˈ æ l dʒ iː / AL-jee; [3] sg.: alga / ˈ æ l ɡ ə / AL-gə) is an informal term for any organisms of a large and diverse group of photosynthetic eukaryotes, which include species from multiple distinct clades.

2024年9月11日 · Algae are a diverse group of photosynthetic organisms that primarily live in aquatic habitats. The word “algae” is the plural of the singular term “alga”. The study of algae is phycology. Algae play a critical role in the environment and human industry, from forming the basis of aquatic food chains to being used in pharmaceuticals and ...

“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.

2016年6月4日 · Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp...

2023年3月10日 · Algae are photosynthetic organisms that possess photosynthetic pigments such as chlorophyll. However, they lack true roots, stems, and leaves characteristic of vascular plants. Some of them are unicellular whereas others are multicellular. They may also form colonies. Most algae are aquatic.

2024年1月12日 · Algae are a large and extremely diverse group of eukaryotic, photosynthetic organisms found in aquatic environments. They are simple thalloid plants that play an important role in ecosystems by producing oxygen through photosynthesis.

2024年12月17日 · In most algal cells there is only a single nucleus, although some cells are multinucleate. In addition, some algae are siphonaceous, meaning the many nuclei are not separated by cell walls. The nucleus contains most of the genetic material, or deoxyribonucleic acid (DNA), of the cell.

2019年4月17日 · Algae is a term used to describe a large, diverse group of eukaryotic, photosynthetic organisms. Algae can be unicellular, live in colonies, or even be multicellular. The wide variety algae makes them hard to classify. Algae span both terrestrial and marine environments, growing almost anywhere there is water and sunlight.

2024年6月2日 · 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.
