Answer 2

Answer:

1. The task of your heart is to pump enough blood to deliver a continuous supply of oxygen and other nutrients to the brain and the other vital organs.

4. The cotyledons contain (or in the case of gymnosperms and monocotyledons, have access to) the stored food reserves of the seed. As these reserves are used up, the cotyledons may turn green and begin photosynthesis, or may wither as the first true leaves take over food production for the seedling.

2. The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

5. Also called the throat, your pharynx is the part of the digestive tract that gets the food from your mouth. Branching off the pharynx is the esophagus, which carries food to your stomach, and your trachea or windpipe, which carries air to your lungs.
