Question

What is plasmolysis? Give two similarities and one
difference between mitochondria and plastids.​

Answer 1

Answer:

Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell. Through observation of plasmolysis and deplasmolysis, it is possible to determine the tonicity of the cell's environment as well as the rate solute molecules cross the cellular membrane.

Plastids are similar to mitochondria in that they help in the production and storage of food (glucose). ... The main difference between mitochondria and plastids is that mitochondria are found in all eukaryotic cells, but plastids are exclusive to plants and algae.

Answer 2

Answer:

if plant cells are immersed in a hypotonic solution water will diffuse out of the cell because concentration of water molecules in the cells is more than that in the outer solution due to continuous extreme versus Protoplasm strings and separates from the cell wall this phenomenon is called plasmolysisMitochondria is known as power house of the cell whereas the Plastids are known as the kitchen of the cell. 2. Mitochondria produces energy in the form of ATP whereas Plastids manufacture food i.e., photosynthesis. Plastids occur only in plant and algae cells, but mitochondria are found in all eukaryotic cells.
