5. What is the purpose of vascular tissue in plants? * O to allow the plant to absorb sunlight for making food
to allow fertilization of an egg so the plant can reproduce
to absorb nutrients and water from the environment like a sponge
to allow the movement of water, nutrients, and sugars across a distance

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.

i would think it's dendrites
