Cells

What is a cell?

• A cell is the medium-sized unit endowed with life.

• A cell is the largest unit endowed with life.

• A cell is the smallest unit endowed with life.

• A cell is the single unit endowed with life.

How does cell reproduction occur?

• Cells divide by molecular division. Red blood cells have to duplicate in order to have cells with the same number of red blood cells and create two cells equal to the previous one.

• Cells divide by mitosis. The DNA has to be duplicated in order to have cells with the same DNA and create two cells that are the same as the previous one.

• Cells are divided by odd and even numbers. They reproduce by joining even with even and odd with odd.

• Cell reproduction occurs when the cell organism of one individual interacts with the cell organism of an individual of the opposite sex.

Within the cell membrane there are two main compartments, which are ?

• The cytoplasm

  The nucleus

• The prokaryote

  The eukaryote

• DNA

  RNA

• Sodium

  Potassium

How are cells classified?

• All cells can be classified into two groups: eukaryotes and prokaryotes.

• All cells can be classified into two groups: garotas and paraguayas.

• All cells can be classified into two groups: payaringan and paranaense.

• All cells can be classified into two groups: mitochondria and RNA.

Name one component of the cytoplasm

• Dendrita

• Mielina

• Axon

• Mitochondria

What is the main difference between eukaryotic and prokaryotic cells?

• The main difference is that eukaryotic cells have nitric acid and prokaryotic cells do not.

• The main difference is that eukaryotic cells have mitochondria and prokaryotic cells do not.

• The main difference is that eukaryotic cells have a nucleus and prokaryotic cells do not.

• The main difference is that eukaryotic cells are intelligent and prokaryotic cells are not.

The cells of multicellular organisms are surrounded by an extracellular component, external to the plasma membrane, known as the:

The cell is surrounded by a membrane, with receptors on the surface; in addition, it has several small structures inside such as:

In plants, the extracellular matrix is called the extracellular matrix:
