1
Which plant organ is primarily responsible for providing structural support to the leaves?
Answer:
Stem
The stem serves as the primary axis of the plant, providing structural support for leaves, flowers, and fruits. It also acts as a conduit for the transport of water and minerals from the roots to the leaves, and organic nutrients from the leaves to other parts of the plant.
2
What structure gives rise to the branches of a plant?
Answer:
Trunk
The trunk or main stem acts as the primary axis from which lateral branches emerge. These branches develop from axillary buds located at the nodes of the stem, allowing the plant to expand its canopy and optimize light interception for photosynthesis.
3
Which of the following plant parts typically grows underground?
Answer:
Rhizome
A rhizome is a modified underground stem that grows horizontally. It serves as a storage organ for starch and proteins, allowing the plant to survive adverse conditions and facilitating vegetative reproduction by producing new shoots and roots from its nodes.
