Susan planted a few sunflower seedlings in her garden. after a few days, she noticed the appearance of tiny leaves at the apex. activity in which part of the plant stem could have caused this?
a. apical meristem tissue
b. lateral meristem tissue
c. vascular cambium tissue

A: Apical Meristem Tissue

Explanation:

Meristems (or metistamatic tissues) are groups of actively dividing cells. In plants, these meristems are divided into 3 main groups:

The appearance of tiny leaves at the apex of the sunflower planted by Susan must have been due to cell division activities in the apical shoot regions of the seedlings.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
