Oligosaccharides are long chains of lipids linked to proteins and phospholipids on the surface of cells.
(a) true
(b) false

False

Explanation:

Oligosaccharides (OS) are short chains of monosaccharides (between 2 and 10) that has a diverse variety of functions in biology.

In the human body, for example, OS can be linked to phospholipids (these are called glycoproteins) and function as cell markers for immunological processes and cell-to-cell interaction.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

explanation:

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
