Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the function of a plant’s stem?
A
To support the plant and transport nutrients and water between the plant’s roots and leaves
B
To make the plant taller
C
To help the plant reproduce
D
To keep the plant in the ground
Explanation: 

Detailed explanation-1: -The stem conducts water and nutrient minerals from their site of absorption in the roots to the leaves by means of certain vascular tissues in the xylem. The movement of synthesized foods from the leaves to other plant organs occurs chiefly through other vascular tissues in the stem called phloem.

Detailed explanation-2: -Water Transport from Roots to Shoots The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement.

Detailed explanation-3: -The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.

Detailed explanation-4: -Stems carry water and nutrients taken up by the roots to the leaves. Then the food produced by the leaves moves to other parts of the plant. The cells that do this work are called the xylem cells. They move water.

Detailed explanation-5: -Support: Primary function of the stem is to hold up buds, flowers, leaves, and fruits to the plant. Along with the roots, a stem anchors the plants and helps them to stand upright and perpendicular to the ground.
