(b) In the game of tug of war, Team A is applying a force of 100 N along the east direction and Team

B is applying a force of 200 N along the west direction. Write down the magnitude and direction

of the net force.

Answer 2

Meristematic cells are actively dividing undifferentiated cells present at different locations in a plant body which helps in the primary (apical and intercalary meristem) and secondary growth (lateral meristem) in plants.

The characteristics of meristematic cells are:-

1)The cells are isodiametric with thin cellulosic cell walls with no secondary cell wall.

2) They divide rapidly hence, there is no stored food in these cells.

3) They are compactly arranged cells with no intercellular spaces.

4) They have a dense cytoplasm with a prominent nucleus.

5) Endoplasmic reticulum and mitochondria are not fully developed in these cells.

6) They are the most metabolically active cells.

So, the correct answer is 'Thin wall, dense protoplasm, no intercellular spaces, isodiametric and nucleate'.
