🥔 Potato Growth and Structure:
→ In potatoes, the underground portion is a modified stem.
→ It stores reserve food and has all characteristics of a stem, such as roots and shoots appearing from it, and it has buds (eyes).
→ Potato is a tuber (the green part seen in young potatoes carries out photosynthesis).
→ It is called a modified stem as it has scaly leaves, nodes, internodes, and adventitious roots, characteristic of stems.
→ Potato tuber bears buds in small pits known as eyes.
→ Buds develop into branches, and some branches become green, erect, and leafy stems that grow horizontally underground.
📝 Additional Information
→ The first step in the process of plant growth is seed germination.
→ The seed germinates when favorable conditions for growth exist in the environment.
→ In the absence of such favorable conditions, the seeds do not germinate and go into a period of suspended growth or rest.
→ Once favorable conditions return, the seeds resume metabolic activities, and growth takes place.
→ The root system begins its development from the embryonic root, also called the radicle, which grows out of the seed after the seed has absorbed water.
→ This is the primary root of a new plant.
→ The tip of the root is covered by a mass of loose cells called the root cap.
