What is protoplasm made of?

The protoplasm is the cell’s living content. It is composed primarily of biomolecules such as nucleic acids, proteins, lipids, and carbohydrates. It also has inorganic salts and water molecules. The protoplasm is surrounded by the cell membrane.

Which two components make up the protoplasm of a cell?

Protoplasm comprises the living part of the cell. It includes cytoplasm, nucleus and other organelles.

What is protoplasm of a cell?

Protoplasm, the cytoplasm and nucleus of a cell. The term was first defined in 1835 as the ground substance of living material and, hence, responsible for all living processes.

What 2 things are the cytoplasm made up of?

The main components of the cytoplasm are cytosol (a gel-like substance), the organelles (the cell’s internal sub-structures), and various cytoplasmic inclusions. The cytoplasm is about 80% water and usually colorless.

What do Plasmodesmata mean?

Plasmodesmata (Pd) are co-axial membranous channels that cross walls of adjacent plant cells, linking the cytoplasm, plasma membranes and endoplasmic reticulum (ER) of cells and allowing direct cytoplasmic cell-to-cell communication of both small molecules and macromolecules (proteins and RNA).

Where is the cytoplasm made?

1.4 Cytoplasm. The cytoplasm is the gel-like substance enclosed within the cell membrane, which is made up of water, proteins, lipids, nucleic acids, inorganic salts, etc.

Where is cytoplasm found?

Cytoplasm, the semifluid substance of a cell that is external to the nuclear membrane and internal to the cellular membrane, sometimes described as the nonnuclear content of protoplasm. In eukaryotes (i.e., cells having a nucleus), the cytoplasm contains all of the organelles.
