Answer;
-Phospholipids and protein
Explanation;
-The plasma membrane is composed of a phospholipid bilayer arranged back-to-back. It is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell.
- The membrane is an extremely thin layer of lipids and protein that forms outer boundary of every cell, It controls movement of molecules between the cell and its environment, Participates in joining cells to form tissues and organs and also plays important role in the ability of a cell to respond to changes in the cell's environment.
The roots do absorb water and is the anchors the plant to stand it up. But it does not make food by itself
Answer: The cell that is being observed under the microscope have flagellum and lysosomes. The function of flagella is to help in the movement of the cell. This is considered as the locomotory organ of the cells. The membrane bound cell organelles lysosomes contains hydrolytic enzymes that is used by the cell for the breakdown of food ingested by cell.
Conclusion is that the cell can perform locomotion and digestion of small molecules.
Make a paraffin block with that wing present inside. Now make fine slices of that block. Take one fine & even slice on a slide & then stain it.
Hope this helps you!
Certain genes that allow for a certain thing to happen are turned on or turned off as needed. A brain cell may have the gene needed to send electrical pulses to other brain cells or other parts of the body, whereas a heart cell may have the genes that allow it to contract to pump blood. (I don't know if those are real genes, but hopefully you get the idea)
