Water droplets are are spherical in shape due to a phenomenon called surface tension. In a liquid this acts on the surface of a freely falling drop to minimize its area.
Over time the dye will slowly dye a part of the petals because the water column was still functioning.
d. Xylem and phloem are composed of living cells.
a. Phloem transports nutrients from the photosynthesizing cells to the rest of the plant.
During photosynthesis, the stomata needs to be open to allow CO2 to enter and O2 to exit. Water then evaporates from the leaf, creating transpiration. Describe one way in which plants can adapt to changes in water supply. Aquatic plants are buoyant and resistant to water movement.
Ranunculus: Black circles in a plus formation is the Xylem, and the smaller green circles surrounding it are Phloem. Tilia: The pale green is the Xylem , and the lime green is the Phloem. The Phloem is on the outer circle then the Xylem circle then the Pith.
Phloem is composed of living cells that form long, sieve-like tubes that transport the carbohydrate products of photosynthesis from the leaves to the rest of the plant .
