do volvox have a nucleus?

Nucleolus →contains the nucleus of the cell. Volvox: common single celled pond algae that consists of one or more colonies. Each cell uses its flagella simultaneously to move the colony.

Nuclear envelope – how it helps. The nuclear envelope keeps the contents of the nucleus, called the nucleoplasm, separate from the cytoplasm of the cell. The all-important genetic material, mainly the DNA is kept separate and relatively safe from the chemical reactions taking place in the cytoplasm.

The nucleus contains mainly nucleoproteins composed of nucleic acid and proteins, besides enzymes and inorganic salts.

The nucleus is a membrane-bound organelle within the cytoplasm where the genome is housed in a eukaryote. The nucleoid region is just the spot in the cytoplasm of a prokaryotic cell where the genome happens to be hanging out -- the genome is not separated from the rest of the cytoplasm by any membrane.

Prokaryotic Cells Prokaryotes do not have a true nucleus: the DNA is in the nucleoid region rather than a nuclear membrane. Prokaryotic cells have only: prokaryotic flagella, pili, capsule, cell wall, plasma membrane, ribosomes, and nucleoid region with DNA.

There are two types of cell, prokaryotic (bacteria) and eukaryotic (animal, plant, fungi and protoctista (unicellular organisms)). Prokaryotes have no nucleolus – the DNA is in the cytoplasm, and it can from small circular strands of DNA called plasmids. Eukaryotic cells all have their DNA enclosed in a nucleus.

The nuclear envelope is a double-membrane structure that constitutes the outermost portion of the nucleus (Figure 1). ... The nucleoplasm is the semi-solid fluid inside the nucleus, where we find the chromatin and the nucleolus.

Volvo Cars is owned by Chinese carmaker Geely Holdings, which also owns Lotus and Proton. The S90 is made in Volvo Cars' plant in Daqing, while the XC60 is from its factory in Chengdu. The Swedish brand was the first Western carmaker to export a China-made premium model to the United States back in 2015.

They are commonly used in laboratory demonstrations. Each cell of the filaments features a large central vacuole, within which the nucleus is suspended by fine strands of cytoplasm. The chloroplasts form a spiral around the vacuole and have specialized bodies known as pyrenoids that store starch.

The nucleus of a eukaryotic cell contains the DNA, the genetic material of the cell. ... The nucleolus is the central portion of the cell nucleus and is composed of ribosomal RNA, proteins and DNA. It also contains ribosomes in various stages of synthesis. The nucleolus accomplishes the manufacture of the ribosomes.

The nucleus is the “control center” of a cell. It contains all of the cell's genetic material. While skeletal muscle cells can have multiple nuclei, cardiac muscle cells typically only have one nucleus.

The Nucleoid In contrast to the nucleus of a eukaryotic cell, it is not surrounded by a nuclear membrane. The genome of prokaryotic organisms generally is a circular, double-stranded piece of DNA, of which multiple copies may exist at any time. ... Sometimes even strands of what is thought to be DNA are visible.

A eukaryotic nucleus is membrane bounded but the nucleoid is not membrane bounded. Nucleus is a large and organized genome containing organelle of a eukaryotic cell whereas the nucleoid is a spot where genome is hanging out freely in cytoplasm.

Plant cells lack centrioles or spindle pole bodies except in their flagellate male gametes, and they are entirely absent in the conifers and flowering plants. Instead, the nuclear envelope itself appears to function as the main MTOC for microtubule nucleation and spindle organization during plant cell mitosis.

Organization of the Nucleus and Its DNA Like most other cellular organelles, the nucleus is surrounded by a membrane called the nuclear envelope. This membranous covering consists of two adjacent lipid bilayers with a thin fluid space in between them. Spanning these two bilayers are nuclear pores.

In the unicellular biflagellate green alga Chlamydomonas reinhardtii each basal body is linked to the nucleus by a fibrous nucleus-basal body connector (NBBC) that contains the calcium-binding protein centrin.
