What organelle propels substances across cells?
What organelle propels substances across cells?
Both prokaryotic and eukaryotic cells contain structures known as cilia and flagella. These extensions from the cell surface aid in cell movement. They also help to move substances around cells and direct the flow of substances along tracts.
What propels substances that are outside the cell?
Cell movement structures
| Organelle | Function |
|---|---|
| Flagella | Whip/tail-like structure that helps propel the cell forward |
| Cilia | Short, hair-like structure that surround the cell and help it move |
| Pseudopodia | Extension of cytoplasm into the cell membrane that allows the cell to “crawl” |
What cell organelle is responsible for powering the cell?
Mitochondria
Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy “currency” of the cell that powers the cell’s metabolic activities.
What is cilia and flagella function?
Flagella are long, wavy structures that extend from the plasma membrane and are used to move an entire cell. • Cilia are short, hair-like structures that are used to move entire cells or substances along the outer surface of the cell.
What is the function of lysosomes?
Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.
What is the job of the Golgi apparatus?
The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
What do lysosomes do for the cell?
Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.
How do mitochondria move around the cell?
Mitochondria primarily move by the action of molecular motors along cytoskeletal elements (Figure 2 and Table 1). Like other organelles, mitochondria associate with specific motor isoforms through organelle-specific adaptors, and their movement is sensitive to disruption of these motors and adaptor proteins.
