Chemistry
The positive portion found in the nucleus of an atom
What is proton?
This organelle is the site for intracellular digestion.
What is the lysosome?
A general term for movement of substances from high to low concentrations, without using energy
What is passive transport?
During this phase of mitosis, chromosomes are pulled apart and moved to opposite poles of the cell.
What is anaphase?
These directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate between cells.
What are gap junctions?
This neutral part of the nucleus of an atom makes up approximately half the mass of the atom.
What is the neutron?
This organelle is responsible for housing the DNA and it controls cell function. It is the biggest organelle..
What is the nucleus?
The movement of large substances out of the membrane, against the concentration gradient, which require energy.
What is exocytosis?
During this phase of mitosis, the nuclear membrane disappears, and the DNA condenses to form chromosomes.
What is prophase?
This is what identical halves of a chromosome are called.
What are sister chromatids?
This subatomic particle floats around the positively charged middle, making up the majority of the volume in an atom.
What are the electrons?
This organelle takes products made from the endoplasmic reticulum, packages them in vesicles, and sends them out to other parts of the cell or out of the cell.
What is the Golgi apparatus?
What is the process called, where solid substances are moved across the membrane, using energy.
What is phagocytosis?
The cytoplasm completely splits to form two separate daughter cells.
What is cytokinesis?
The organelles responsible for pulling the genetic matter to opposite poles..
What is centrioles?
How to determine the number of electrons in an atom, which is the same as the number of protons.
What is the atomic number?
System of filaments running throughout the cell that are anchored to the cell membrane and nucleus, providing structure and support.
What is the cytoskeleton?
A solution with a lower concentration of solutes outside than another solution, typically inside the cell. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.
What is hypotonic solution?
During this phase of mitosis, the cell duplicates its DNA, organelles, and finishes growing.
What is interphase?
a cell structure specialized for cell-to-cell adhesion
What are desmosomes?
How to determine the number of neutrons.
What is mass number minus atomic number?
This organelle uses cellular respiration in order to make ATP, which is energy for the cell to use.
What is Mitochondria?
This form of energy, is used to move substances into or out of the cell, during active transport, and is made in the mitochondria.
What is ATP, adenosine triphosphate?
During this phase of mitosis, the chromosomes line up in the middle of the cell.
What is metaphase?
multiprotein junctional complexes whose general function is to prevent leakage of transported solutes and water and seals the paracellular pathway - like to not let the blood leak out
What are tight junctions?
