Answer:
- The two lines on the outside of the chloroplast indicate a double membrane: True
- The Golgi apparatus is not shown in this cell but this does not mean that this organelle does not occur in the cell: True
- The relative dimensions and placement of the membranes and organelles in this model are exact representations of those structures in a living cell: False
- The large structure in the center is a nucleus: False
- This cell is capable of photosynthesis: True
Explanation:
- Chloroplast, like mitochondra, have double membrane called the chloroplast envelope. Hence the first statement is true.
- Golgi apparatus is found in all plant and animal cell. It is usually located close to endoplasmic reticulum. Hence this statement is true.
- The relative dimensions and placement of the membranes and organelles in this model are not an exact representation of those structures found in living cell. Hence its a false statement.
- The large structure in the centre is vacuole and not nucleus. Hence its a false statement.
- Since its a plant cell so it is capable of photosynthesis. Hence its a true statement
Lipids are generally defined as nonpolar compounds in the body that are possessing properties of being hydrophobic and amphiphilic. Lipids play an essential role in living organisms because they comprise the formation of cellular membranes, hormones, vitamins, and most especially energy storage.
There are a wide classification of lipids. Examples are fatty acids in monoglycerides, diglycerides and triglycerides. Other examples are cholesterol, vitamins, waxes, and other phospholipids. The general structure of common lipids in the body like triglycerides and phospholipids are shown in the pictures attached.
