What carry certain molecules from place to place in a cell?
Vesicles-carries certain molecules from place to place within a cell.
What transports molecules around the cell?
Let’s Review
| Transport | Molecules moved | Uses energy? |
|---|---|---|
| Simple diffusion | Small, nonpolar | No |
| Facilitated diffusion | Polar molecules, larger ions | No |
| Primary active transport | Molecules moving against their gradient coupled to the hydrolysis of ATP | Yes |
| Secondary active transport | Molecule going with + molecule going against gradient | Yes |
What part of a cell carries?
Animal cells and plant cells
| Part | Function |
|---|---|
| Cell membrane | Controls the movement of substances into and out of the cell |
| Cytoplasm | Jelly-like substance, where chemical reactions happen |
| Nucleus | Carries genetic information and controls what happens inside the cell |
| Mitochondria | Where most respiration reactions happen |
How do the nucleus and Golgi work together?
The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER. It is also involved in the transport of lipids around the cell. Pieces of the Golgi membrane pinch off to form vesicles that transport molecules around the cell.
What organelle transports proteins around the cell?
The Endoplasmic Reticulum
The Endoplasmic Reticulum or ER is an extensive system of internal membranes that move proteins and other substances through the cell. The part of the ER with attached ribosomes is called the rough ER. The rough ER helps transport proteins that are made by the attached ribosomes.
What cell organelle carries protein to the different parts of the cell?
The endoplasmic reticulum (ER) is involved in the synthesis of lipids and synthesis and transport of proteins. The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell.
What do the organelles in a cell represent?
Floating around in the cytoplasm are small structures called organelles. Like the organs in your own body, each one carries out a specific function necessary for the cell to survive. Imagine the cells as a miniature city. The organelles might represent companies, places, or parts of the city because they each have similar jobs.
What are small structures floating around in the cytoplasm?
Answer key: CELL CITY INTRODUCTION! Floating around in the cytoplasm are small structures called organelles. Like the organs in your own body, each one carries out a specific function necessary for the cell to survive. Imagine the cells as a miniature city.
What makes a cell a ” cell city “?
CELL CITY INTRODUCTION! Floating around in the cytoplasm are small structures called organelles. Like the organs in your own body, each one carries out a specific function necessary for the cell to survive. Imagine the cells as a miniature city.
How does the nucleus control the activities of the cell?
The nucleus controls all of the activities of the cell as city hall controls all the activities in of the city. 2. The cell membraneis a thin, flexible envelope that surrounds the cell. It allows the cell to change shape and controls what goes into and out of the cell a.
