Review the diagram of the animal cell given below and answer the following questions: a. identify the 9 cell structures that are labeled in the animal cell diagram given below and explain their functions. (clearly indicate the letter that corresponds to each cell structure) b. pick two of the structures that are labeled and explain how they work together and how their functions are vital in keeping the cell alive.

Animal cells are a usual example of a eukaryotic cell, enveloped by a plasma membrane, and comprising a membrane-bound nucleus and organelles. Like the cells of plants and fungi, they do not exhibit cell wall.  

The labeling in the mentioned diagram is:  

A. Rough endoplasmic reticulum

B. Cytoplasm

C. Smooth endoplasmic reticulum

D. Nucleolus

E. Nucleus

F. Mitochondria

G. Golgi apparatus

H. Lysosome

I. Plasma membrane

The Golgi apparatus functions closely with the rough endoplasmic reticulum. When a protein is formed in the rough endoplasmic reticulum, then the formation of transition vesicle takes place. This vesicle or sac floats via the cytoplasm to the Golgi apparatus and is then absorbed. From there, the vesicle travels to the membrane of the cell and the molecules are then discharged out of the cell.  

The animal cells are generally eukaryotic cells, which consists of membrane bound organelles like nucleus, cytoplasm, plasma membrane, mitochondria, and Golgi apparatus. The given image is of an animal cell, and the labelled parts are:

The function of each organelle are as follows:

The ribosomes are involved in the synthesis of the proteins. These proteins are then entered in the rough endoplasmic reticulum, from where it is released to the Golgi complex via vesicles. The Golgi complex then modifies protein molecule and release in the cell.

Therefore, the cell organelles perform various functions for the survival of the cell.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
