Question

The basic unit of life is a cell. A student is studying for an exam comparing structure and functions of a plant cell and an animal cell. The student has to be able to identify the different organelles and the most likely location. Which type of proposed model would be best for the student to utilize in their studies and why?

A) The student should utilize a mathematical model comparing the percent of types of organelles in each so that they understand
the amount in each type of cell.
B) The student should utilize a hand-held size physical model of each type of cell so that they are able to see and compare the types
and locations of the organelles and how the organelle’s functions relate.
C) The student should utilize microscopic slides with real animal and plant cells so that they are able to identify the organelles and
location in a real cell and not a pretend one.
D) The student should utilize a model of the human body and plant so that they can understand how the cells of each type work with
the rest of the structure.
E) The student should utilize a conceptual model that differentiates between the animal cell and plant cell in general and which type
of cell is better.

Answer 1

Answer: E) The student should utilize a conceptual model that differentiates between the animal cell and plant cell in general and which type

of cell is better.

Explanation:

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.

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts.

Animal cells have centrioles, centrosomes (discussed under the cytoskeleton), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

The different types of plant cells include- collenchyma, sclerenchyma, parenchyma, xylem, and phloem.
