Q1: Which organelle would you associate with elimination of old and worn out cells? Why?Q2: Describe an activity to demonstrate endosmosis and exosmosis. Draw a diagram in support of theactivity.Q3:a. Draw a plant cell and name seven important organelles found in itb. Name one organelle that can make some of its own protein in a plant cell and also mention onefunction of such an organelle.Q42) Where are chromosomes located?b) What are they composed of?c) What is chromatin material and how does it change just before the cell divides?d) What is their chemical compositionwho will answer all the answer I will mark it as brainliest but you have to answer all the questions
Answers
Answer:
can you please write the question in steps it is not understandable
Explanation:
Answer:
1. Lysosomes help in digestion of old and worn cells.
2.Endosmosis
When a cell is kept in a hypertonic solution, the water starts moving into the cell from a region of higher concerntration to the region of lower concerntration is called endosmosis. As a result the cell swells up.
Activity -
Buy some raisens
Put them into a hypertonic solution (eg. water)
Now wait for some time and observe the raisens.
The raisens starts swelling up.
Observation - Through this activity we observe that after putting raisens in hypotonic solution the raisens swells up. Their is also an increase in thier weight.
Exosmosis
When a cell is kept in a hypotonic solution, the inner content of cell shrinks as the water moves from the region of higher concerntraion to the region of lower concerntration. This is called exosmosis.
Activity -
Buy some raisens
Put them in a hypotonic solution (eg. A sports drink with a lot of salts in it)
Wait for a while and observe that the cell starts shrinking
Observation - Through this actvity we observe that after putting raisens in a hypotonic solution the raisens starts losing water content and gets shrinked.
