Give function
a. Plasma membrane
b. Cytoplasm
c. Lysosome
d. Vacuole
e. Nucleus
Answers
Answer:
a. The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.
b. Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.
c.A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
d. Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. ... The large central vacuoles often found in plant cells enable them to attain a large size without accumulating the bulk that would make metabolism difficult.
e. The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.
Answer:
plasma membrane
The plasma membrane is a biological membrane that is a barrier between the outer and inner surface of a cell. It is composed of a phospholipid bilayer with embedded proteins.
The primary function of the plasma membrane is to protect the cell from its surroundings. It is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
Plasma membrane serves as a base of attachment for the cytoskeleton in some organisms and cell walls in other organisms.
cytoplasm
The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.
lysosome
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
vacuole
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
nucleus
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
