Do algae have eukaryotic cells?
Algal cells are eukaryotic and contain three types of double-membrane-bound organelles: the nucleus, the chloroplast, and the mitochondrion.
In most algal cells there is only a single nucleus, although some cells are multinucleate..
What is algae classification?
Algae are photosynthetic organisms belonging to the kingdom Protista. Alga is the singular of algae with a changing size from microscopic unicellular micro-algae (Chlorella and Diatoms) to large massive kelps that are usually a length extending in meters (200 feet) and then there’s brown alga.
Is yeast a prokaryote?
Although yeast are single-celled organisms, they possess a cellular organization similar to that of higher organisms, including humans. … This classifies them as eukaryotic organisms, unlike their single-celled counterparts, bacteria, which do not have a nucleus and are considered prokaryotes.
Is algae made of one or more cells?
Algae can be single-celled (unicellular), or they may be large and comprised of many cells. Algae can occur in salt or fresh waters, or on the surfaces of moist soil or rocks. The multicellular algae develop specialized tissues, but they lack the true stems, leaves, or roots of the more complex, higher plants.
Do viruses have DNA?
Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.
Is virus prokaryotic or eukaryotic?
Eukaryotes include such microorganisms as fungi, protozoa, and simple algae. Viruses are considered neither prokaryotes nor eukaryotes because they lack the characteristics of living things, except the ability to replicate (which they accomplish only in living cells).
In which class of algae the cells are prokaryotic?
Prokaryotic Algae: The blue-green algae (Cyanophyceae or Cyanophycophyta) are prokaryotic algae. In these algae, their nuclear materials, deoxyribo-nucleic acid (DNA), is not delimited from the remainder of the protoplasm by a nuclear membrane, but rather it is dispersed to some degree throughout the cell.
Which algae is not eukaryotic?
Thus, the correct answer is ‘Blue green algae. ‘
Is algae a prokaryote?
Algae are eukaryotic organisms, which are organisms whose cells contain a nucleus and other structures (organelles) enclosed within membranes. Algae are not cyanobacteria. … Cyanobacteria are prokaryotes, which lack membrane-bound organelles and have a single circular chromosome.
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.
Does algae reproduce asexually?
Algae regenerate by sexual reproduction, involving male and female gametes (sex cells), by asexual reproduction, or by both ways. … Many small algae reproduce asexually by ordinary cell division or by fragmentation, whereas larger algae reproduce by spores.
Do prokaryotes have DNA?
Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane.
