Which of the following parts of tree have limited dimensions, fall periodically and some time repeatedly?
1 The leaves, flowers and fruits
2 The stem, leaves and flowers
3 The stem, root and twigs
4 The leaves, fruits and roots
Explanation:
Trees continue to increase in height or girth over a period of time. However, the leaves, flowers and fruits of the same tree have limited dimensions and also appear and fall periodically and some time repeatedly.

Lateral meristem, vascular cambium and corkcambium are responsible for which of the following event in plants?
1 The increase in the girth of the organs in which they are active
2 Secondary growth of the plants
3 Both 1 and 2
4 Primary growth of the plants.
Explanation:
In dicotyledonous plants and gymnosperms, the lateral meristems, vascular cambium and cork-cambium appear later in life. These are the meristems that cause the increase in the girth of the organs in which they are active. This is known as secondary growth of the plant.

One single maize root apical mersitem can give rise to how many new cells per hour?
1 More than 17,500 new cells per hour
2 More than 3,50,000 new cells per hour
3 More than 17,5000 new cells per hour
4 More than 55,500 new cells per hour
Explanation:
One single maize root apical meritem can give rise to more than 17,500 new cells per hour, in this case growth is expressed as increase in cell number.
