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

"Apical Meristem Tissue" is the part of the plant among the following choices given in the question where the activity in the plant stem could have caused this. The correct option among all the options that are given in the question is the first option or option "A". I hope that the answer has come to your help.

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:

Apical meristems refers to the tissues around the apices of roots, new shoots and leaves. They are responsible for shoot and root elongation as well as the appearance of new leaves.Intercalary meristems are tissues found in between branches. They are responsible for rapid growth in most monocotsLateral meristems are those found in the lateral regions of plants. They are responsible for increase in girths in plants, especially the woody ones.

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.

Hence, the correct answer is A
