Answer:
B. When beetroot cells are placed in a solution with cellulase, the solution remains clear.
Explanation:
Cell membrane are not destroyed or damaged as cellulase digests cellulose, rather it damages the structure of the cell wall.
In conclusion, even though the Beetroot cell wall has been damaged, the lack of change in the color of the solution suggests that the betalain is not leaking out thereby refuting the claim that the alternative hypothesis that selective permeability is a consequence of the cell wall.
Answer:
Mithocondria and Chloroplasts.
Explanation:
They both contain their own DNA and Ribosomes
Facts:
Mitochondria are called "The power house" of the cell, they are responsible for breaking down fuel molecules and capturing energy in cellular respiration.
Chloropalst are found in plants and algae (not in humans). They're responsible for capturing light energy to make sugars in photosynthesis. Without the chloropalst,plants wouldn't be abale to make their own food, this will cause their death and then ours.
