<span>Unsaturated fat
Saturated fats are solid at room temperature while unsaturated fats are liquid at room temperature. This is because these two kinds of fats differ in their chemical structure. Saturated fats do not have double bonds between the molecules which means there are no gaps and the fat is saturated with hydrogen molecules. Because there are no gaps, these fats tend to pack more closely together. Unsaturated fats have double bonds which break up the chain of hydrogen molecules and create gaps allowing them to pack loosely and can thus liquefy at room temperature.</span>
Answer:
Cell structures which can be seen missing from Clara's model are:
Ribosomes: Ribosomes are the organelles which are involved in the synthesis of proteins Hence, it is the site where translation occurs. The mRNA travels to the ribosomes once formed. Usually, ribosomes which are attached to rough endoplasmic reticulum are the sites where translation occurs.
Golgi-complex: Golgi-complex is the organelle which is involved in the modification and packaging of proteins. Such modifications allows the protein to be transported outside the cell without being degraded.
Answer:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
The key difference between microspore and pollen grain is that microspore is the small spore that develops into the male gametophyte in plants while pollen grain is the small grain that contains the male gametophyte.
