Does algae have nucleic acid?

Does algae have nucleic acid?

The algae biomass contains carbohydrate, protein, lipid, and nucleic acid.

What is algae nucleus?

Nucleus. The nucleus in algae is surrounded by a double membrane nuclear envelope – as in other eukaryotic organisms – and contains DNA. The remainder of the algae have an eukaryotic nucleus.

Do algae have ribosomes?

The work of Taylor and Storck (8) has shown that blue-green algae have 70 S ribosomes whereas other workers found that green algae have 80 S ribosomes in the cytoplasm (9, 22).

Do cyanobacteria have nucleus?

Cyanobacteria, and bacteria in general, are prokaryotic life forms. This basically means that their cells don’t have organelles (tiny structures inside cells that carry out specific functions) and do not have distinct nuclei—their genetic material mixes in with the rest of the cell.

Is algae a plant or bacteria?

Algae are sometimes considered plants and sometimes considered “protists” (a grab-bag category of generally distantly related organisms that are grouped on the basis of not being animals, plants, fungi, bacteria, or archaeans).

Is algae a plant or protist?

Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. Like plants, algae contain chlorophyll and make food by photosynthesis. Types of algae include red and green algae, euglenids, and dinoflagellates.

Do viruses have a nucleus?

Viruses do not have nuclei, organelles, or cytoplasm like cells do, and so they have no way to monitor or create change in their internal environment.

Is there nucleus in virus?

Surprisingly, a nucleus-like structure that forms during viral infection of bacteria is the site of viral DNA replication (link to paper). During infection of Pseudomonas bacteria with the phage 2O1phi2-1, a separate compartment forms in which viral DNA replication takes place.

Is algae a prokaryote?

Algal cells are eukaryotic and contain three types of double-membrane-bound organelles: the nucleus, the chloroplast, and the mitochondrion.

Is algae a protist?

algae, singular alga, 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.

What are 3 characteristics of cyanobacteria?

Defining cyanobacteria characteristics are a tolerance of extreme conditions and an ability to exist without vitamins. They use phosphorus, iron and other micronutrients, and ammonia or nitrate as a nitrogen supply. Some types of cyanobacteria are filamentous and don’t need sunlight.

Is algae plant or animal with reasons?

Algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.

Where is the nucleus located in an algae?

In all eukaryotic algae (Chlorophyceae etc.), the nucleus is a well-organised spherical or ellip­tical body. It remains surrounded by a distinct nuclear membrane. The inner side is occupied by a chromatin reticulum embedded in a matrix called karyolymph.

What kind of organism is an algae cell?

Algae are eukaryotic organisms, which are organisms whose cells contain a nucleus and other structures (organelles) enclosed within membranes.

Where are microtubules found in an algae cell?

Microtubules, tubelike structures formed from tubulin proteins, are present in most cells. In many algae, microtubules appear and disappear as needed. Microtubules provide a rigid structure, or cytoskeleton, in the cell that helps determine and maintain the shape of the cell, especially in species without cell walls.

What are the characteristics of an eukaryotic algae?

So what are the characteristics of algae? 1 Eukaryotic organisms: As mentioned above, algae are eukaryotic organisms. The structure of a eukaryote (a typical… 2 Live in moist environments These organisms lack a waxy cuticle (the wax in terrestrial plants prevents water loss). 3 Contain chlorophyll More
