Answer:
When it comes to photosynthesis, the most important parts of the plant are the leaves. Their cells and structures are specialized to take in light and allow for gas exchange with the air around them. They also contain vascular structures that transport water from the roots into the cells that carry out photosynthesis.
1. The plant’s vascular tissues—xylem and phloem—transport water to the leaves and carry glucose away from the leaves.
Anyone who cares for plants could probably tell you that pouring water directly onto the leaves isn’t the best idea. Plants absorb water from the soil, using their roots.
As you probably already know, water is necessary for photosynthesis, which primarily occurs in the plant’s leaves. You might wonder how the water gets from the roots into the leaves, and the answer is through the plant’s vascular system! Just like the veins and arteries that circulate blood throughout our bodies, the plant’s vascular tissues move water, nutrients, and the products of photosynthesis throughout the plant.
A plant’s vascular tissues move water, nutrients, and the products of photosynthesis throughout the plant.
When a plant’s roots absorb water and nutrients from the soil, these materials move up the stem and into the leaves through the xylem. Capillary action—which relies on liquid’s properties of cohesion, surface tension, and adhesion—is what allows water to “defy gravity” as it travels through the xylem and into the leaves.
Once photosynthesis has occurred, the produced sugars move through the phloem to other parts of the plant to be used in
