In some plants, starch is stored in cell organelles called amyloplasts. Some plant roots and embryos, in the form of seeds and fruit, also serve as storage units for starch. Cells in plant leaves produce starch in the presence of sunlight.
Answer:
starches, sugars, and fats
- speed up chemical reactions in the body / hormones
- transport materials across the body
- regulate body tissues and organs
Ex: insulin
Ex: hemoglobin in the blood transport oxygen around the body..yea XD
Answer:
The central part of the atom, composed of protons and neutrons.
PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.
The smallest component that makes up a chemical element is an atom. Atoms that are neutral or ionized are the building blocks of all solids, liquids, gases, and plasma. A normal atom is 100 picometers across, which is incredibly small.
Protons, which have a positive charge, make up the majority of it, while neutrons, which have no charge, form the remainder. All regular, naturally occurring atoms have protons, neutrons, and electrons that orbit them because they are heavy particles.
A sample's mass in grams should be divided by the periodic table's amu atomic mass, and the result should be multiplied by 6.02 x 1023, or Avogadro's number, to determine how many atoms are there. So, PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.
