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.

Answer from: kutsarver

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:

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 function of each organelle are as follows:

A. Rough endoplasmic reticulum is a membranous structure to which ribosomes are attached. It is involved in the synthesis of proteins. B. Cytoplasm is the gel-like fluid in which all the organelles are suspended. The fluid helps in transportation of substances. C. Smooth endoplasmic Reticulum does not have ribosomes attached to its surface. It is involved in the synthesis of lipids, carbohydrates, and steroids. D. Nucleolus is dense circular structure present in the nucleus of the cell.E. Nucleus is the spherical structure present in the centre of the cell. The nucleus consists of chromosomes. F. Mitochondria is the power-house of the cell. It is involved in the synthesis of high-energy molecules known as ATP. G. Golgi Apparatus is involved in the transportation and modification of proteins. H. Lysosome is involved in the degradation and recycling of the cellular waste. I. Plasma membrane is the outer layer of the cell, which helps in the movement of substance in and out of the cell due its permeability.

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.

For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
