There are various ways to develop or improve plants’ the stems, roots and leaves.
Xylem transports water from the roots up while phloem transports sugar both up or down the stem.
Thank you Gi Hyun!
Thank you Annie!
what plants need in order to create d-glucose are only light energy, CO2, and H2O. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis.
Plants need energy to grow, to replace worn out cells, to get rid of waste and to reproduce. All plants get energy from food.Photosynthesis is the process by which plants make food.
Water Transport through Plants
Xylem is one of the vascular tissues that contain long unbroken columns of water. The tissue brings water to replace losses due to transpiration (water moves upwards from the roots to leaves). When water is pulled out and the plant is eventually at the stage of low pressure, it is called transpiration pull. When xylem delivers enough water through transpiration, the plant is at the stage of high pressure (very healthy!).
Spongy mesophyII wich is a tissue in the leaf provides the main gas exchange surface.
Basically, meristems are discovered at the tips of stems and roots.
The way plants would grow towards the direction of light is called phototropism.
Plants’ flowers polliinate for reproduction. Most of plans do cross-pollination, which is when pollen and pistil in different flowers, and some plants does self-pollination; it occurs when a flower has both pollen and pistill.
