Question: Is cytoplasm a endoplasm?

Endoplasm generally refers to the inner (often granulated), dense part of a cells cytoplasm. This is opposed to the ectoplasm which is the outer (non-granulated) layer of the cytoplasm, which is typically watery and immediately adjacent to the plasma membrane.

Does cytoplasm count as an organelle?

All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm. The portion of the cytoplasm that is not contained in the organelles is called the cytosol. Although cytoplasm may appear to have no form or structure, it is actually highly organized.

Is cytoplasm a cellular compartment?

The major intracellular compartments common to eucaryotic cells are illustrated in Figure 12-1. The nucleus contains the main genome and is the principal site of DNA and RNA synthesis. The surrounding cytoplasm consists of the cytosol and the cytoplasmic organelles suspended in it.

Is cytoplasm part of the nucleus?

Animal cells contain three main regions: plasma membrane, nucleus, and cytoplasm. The nucleus is a cells central organelle, which contains the cells DNA (Figure 3.6). The cytoplasm is composed of two parts, the cytosol and organelles.

Is cytoplasm prokaryotic or eukaryotic?

In eukaryotic cells, which have a nucleus, the cytoplasm is everything between the plasma membrane and the nuclear envelope. In prokaryotes, which lack a nucleus, cytoplasm simply means everything found inside the plasma membrane.

Does a prokaryote 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.

Which is the largest cell of human body?

female ovum The largest cells is an egg cell of ostrich. The longest cell is the nerve cell. The largest cell in the human body is female ovum.

Why do platelets have no nucleus?

Like red blood cells, platelets are derived from myeloid stem cells. Some of these stem cells develop into megakaryoblasts, which give rise to cells called megakaryocytes in the bone marrow. Because they are not cells, platelets dont have their own nuclei.

Can you see a human cell?

The human eye cannot see most cells without the aid of a microscope. However, some large amoebas and bacteria, and some cells within complex multicellular organisms like humans and squid, can be viewed without aids.

What keeps cytoplasm inside?

The job of the cell membrane is to keep the cytoplasm inside, to allow nutrients in and waste products out, and to interact with things outside the cell.

What has no nucleus?

Cells that lack a nucleus are called prokaryotic cells and we define these cells as cells that do not have membrane-bound organelles. So, basically what were saying is that eukaryotes have a nucleus and prokaryotes do not.

Which is biggest cell?

ovum The largest cells is an egg cell of ostrich. The longest cell is the nerve cell. The largest cell in the human body is female ovum.

How much percent of blood is platelets?

Whole blood contains red cells, white cells, and platelets (~45% of volume) suspended in blood plasma (~55% of volume).
