5. Which organelle is known as the powerhouse of the cell? Why?
6. Where do the lipids and proteins constituting the cell membrane
get synthesised?
7. How does an Amoeba obtain its food?
8. What is osmosis?
Answers
Answer:
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
Lipids are synthesized in the Smooth endoplasmic reticulum (SER), and the proteins are synthesized in the rough endoplasmic reticulum (RER).
Amoeba takes in food using temporary finger-like extensions of the cell surface, which fuse over the food particle forming a food vacuole. Inside the food vacuole, complex substances are broken down into simpler ones, diffusing into the cytoplasm.
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
Answer:
5.Mitochondria is known as power house of the cell as it store energy for the plants.
Explanation:
8.Osmosis is the passes of water molecule from a higher concentration to lower concentration with a semi permeable membrane
