I believe that it is the seeds deep inside the flower. They both produce cells by the meiosis.
The right answer is The first image (the left one).
An atrium is an upper cavity of the heart, delimited by a thin wall, receiving blood from the bloodstream. There are two in the human heart, they allow the passage of blood from the veins (cellars and lungs) to the ventricles (right and left).
In its upper part (near the entrance of the superior vena cava) is located the sinus node, microscopic structure from which the electrical impulse which ensures the contraction of the heart (especially atrium) ...
The depolarization of the action potential is conducted step by step in the cells of the right and left atria, accompanied by a contraction of the muscle fibers.

Structure 6 is the Rough Endoplasmic Reticulum ( RER) while structure 7 is the Golgi apparatus.
Explanation:
The RER has ribosomes aligning its outer membrane (reason why it's referred to as called rough ER). The ribosomes manufacture polypeptide chains that enter the lumen of the RER. The polypeptide chains are properly folded using chaperones in the lumen of the RER and undergo post-translation modifications, These proteins then undergo Quality Control checks and the proper ones are allowed to proceed to the Golgi apparatus.
Proteins from the RER reach the Golgi apparatus through vesicles that bud off of the <em>trans</em> side of the RER then fuse with the <em>cis </em>side of the Golgi apparatus. The Golgi perform a few more modifications to the proteins including tagging them for delivery , then packages them. Vesicles carrying the proteins bud off of the <em>trans</em> side of the Golgi and get transported to their destination inside or outside the cell.
