1. larger size in plant cells is matched with vacuole

The central vacuole of plant cells and fungi has a homeostatic function, ensuring cell turgor, and its membrane, the tonoplast, has ion pumps. It contains water, carbohydrates, organic and inorganic ions and pigments. Some central vacuoles are also sites of accumulation of reserves or of particular substances, sometimes toxic (latex, opium ...) even of waste, which confers on them a role of detoxification of the cell.

2. salt and water base is matched with cytoplasm

Eukaryotic cells, bounded by a plasma membrane, contain:

* A Nucleus,

* A cytoplasm, the biological material contained between the plasma membrane (cell membrane) and the nuclear envelope. It is composed by:

- hyaloplasm,

- morphoplasm (organelles).

3. grainy appearance is matched with rough endoplasmic reticulum

The rough endoplasmic reticulum (RER) or granular (REG) is an organelle present in eukaryotic cells. It is one of two types of endoplasmic reticulum, characterized by the presence of ribosomes that give it a rough appearance. Depending on the cell type, the REG will take different names like at the level of neurons: Nissl's body.

4. permeable and flexible is matched with cell membrane

All cells are surrounded by a cell membrane or plasma membrane composed of lipids, proteins and carbohydrates. The contents of the cell can not escape and is retained in its place by this membrane.

The cell must be able to trade with the outside. It must, for example, bring in salts, nutrients, water and must be able to get rid of its waste, usually acidic.

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.
