Number the following steps for the reproductive system of a self pollinating flowering plant in order from 1 to 5.

• _ Pollen tube forms and grows through the style.
• _ Sperm fertilizes the egg.
• _ Pollen is released from the anther.
• _ The pollen tube reaches the ovule within the ovary.
•_ Pollen sticks to the stigma.

1) Pollen is released from the anther.

2) Pollen sticks to the stigma.

3) Pollen tube forms and grows through the style.

4) The pollen tube reaches the ovule within the ovary.

5) Sperm fertilizes the egg.

Explanation:

Pollination is a process in which pollen grains are transfer from anther to stigma of the flower. It occurs through wind, water and insect such as bees. When pollen gets mature, it falls from anther to the stigma. There it makes a tube which goes to the ovary. This pollen reaches the ovary through this tube and combines with ovule and fertilization occurs.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
