You did not provide a drawing but if you the distinguishing features of a plant cell is the presence of chloroplasts and you will notice also that the vacuole is rather big compared to an animal cell. You will also see that a plant cell has a cell wall instead of a cell membrane. It is more rigid than the animal cell membrane.

Cell wall, big vacuole and chloroplasts.  That would indicate that the observer is looking at a plant cell.

gtnhenbr [62]

The parts of the amniotic reptile egg include the amniotic fluid, the albumen, and the shell.

<h3>Parts of an amniotic reptile's egg</h3>

The various parts of amniotic reptile's eggs include:

  1. The external shell which serves as a protective layer
  2. The yolk which supplies energy to the embryo
  3. The albumen supplies the embryo with water and proteins
  4. The extra-embryonic membranes - the chorion, the allantois, and the amnion.

The chorion serves as a channel for gaseous exchange between the embryo and the environment.

The allantois partially functions as waste manager and in respiration. It stores nitrogenous wastes and gets rid of them as well as participates in gaseous exchange along with the chorion.

The amnion protects the embryo against mechanical shocks. It also protects the developing embryo from being dehydrated.

In other words, the 3 extra-embryonic membranes protect, facilitate gaseous exchange, and ensure that wastes are properly disposed of.
