... the area between the nucleus and the cell membrane. The cytoplasm contains other important structures in the cell. Structures inside the cell are called organelles. An organelle is a tiny structure in the cell that preforms a special function within the cell. The mitochondria is greatly important to the cell. In animals, the mitochondria changes the ... also have a structure besides the vacuole called the plastid. The plastid also stores food as well as pigments for the plant. The cytoskeleton in a cell is the frame work that holds the cell together and gives it their shape. The cytosk...

... stem cells of the animal kingdom however continue to exist in plants. They perform the function of growth for the plants. In dicot plants there is a third kind of meristem. Lateral meristem exists in dicot plants and it allows the plant to develop wood and expand during its lifetime (Diagram 3a). As it can be ... the water potential is around -5 to 10 total bars of pressure. At this point the plant has reached its permanent wilting point, below this point plasmolysis will occur. Plasmolysis is the movement of the cytoplasm away from the cell walls. This will result in no movement of water...

... little need to chew them, since digestive enzymes can act directly on animal cells. Herbivores must pulverize the cellulose cell walls of plant tissue before digesting it; the teeth are large and flat, with complex ridges that are well suited for grinding. Humans are omnivores, ... causing a condition called edema. One of the most important blood constituents whose levels are regulated by the liver is glucose. This regulatory function is essential in vertebrates since neurons in the brain depend almost exclusively upon glucose as an energy source. These cells can store very little ... ...

... only under a microscope, and those that can be determined only by chemical tests. Scientists compare the external shapes and sizes of organisms as well as the anatomy and function of internal organs and organ systems, such as the digestive or reproductive systems. Biochemists study and compare the molecular interactions within an organism that enable it to grow, make ... organelles called chloroplasts Parts of the Plants Cells: The many varieties of plant species have distinct cell types that make up individual plants. Similarities do exist among all these cell types; however, these sim...
