What are passageways or hallways of the cell?
CELL ORGANELLES AND FUNCTIONS
| A | B |
|---|---|
| ENDOPLASMIC RETICULUM | Passageways (HALLWAYS) that carry PROTEINS and other material to the cell. |
| RIBOSOMES | Factories to PRODUCE PROTEINS needed for growth and repair of an organism |
| GOLGI BODIES | Like the MAILROOM of the cell–receive proteins/other materials, PACKAGE them, distribute to cell. |
Is a network of passageways?
A network of passageways that carries materials from one part of the cell to another. These small structures function as factories to produce proteins in animal cells. They may “park” on the Endoplasmic Reticulum or float freely in the cytoplasm.
What is a system of tubular passageways in the cell?
Endopalsmic reticulum – is a network of tubular passageways in the cell which is used to transport materials within the cell. Often ribosomes are attached to the inner walls of the E.R. Ribosomes – produce protein within the cell. Vacuoles – are storage tanks for the cells. Vacuoles may store water, food or wastes.
What is the cell’s mailroom?
True, Golgi body is known as the mailroom of the cell. This is because they transport the materials to the destinations. The molecules are packaged in vesicles. The packaged vesicles are moved to the Golgi Apparatus.
What produces the cell’s energy?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What stores waste in a cell?
▶ Vacuole- stores water, food, waste, and other materials.
How many layers of phospholipids make up the cell membrane?
two layers
Phospholipids are the most abundant type of lipid found in the membrane. Phospholipids are made up of two layers, the outer and inner layers. The inside layer is made of hydrophobic fatty acid tails, while the outer layer is made up of hydrophilic polar heads that are pointed toward the water.
