What Two Structures Do Animal Cells Have That Plants Don't
Structurally, constitute and animal cells are very like because they are both eukaryotic cells. They both comprise membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both too comprise like membranes, cytosol, and cytoskeletal elements. The functions of these organelles are extremely similar between the two classes of cells (peroxisomes perform additional complex functions in plant cells having to do with cellular respiration). However, the few differences that exist between plant and animals are very significant and reflect a departure in the functions of each cell.
Plant cells can be larger than animal cells. The normal range for an beast cell varies from 10 to thirty micrometers while that for a institute prison cell stretches from ten to 100 micrometers. Across size, the primary structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the jail cell wall, and vacuoles.
Chloroplasts
In animal cells, the mitochondria produces the bulk of the cells energy from food. It does not have the same function in constitute cells. Establish cells use sunlight as their energy source; the sunlight must be converted into energy inside the cell in a process called photosynthesis. Chloroplasts are the structures that perform this function. They are rather big, double membrane-leap structures (about 5 micrometers across) that comprise the substance chlorophyll, which absorbs sunlight. Additional membranes within the chloroplast contain the structures that actually carry out photosynthesis.
Chloroplasts carry out energy conversion through a complex set of reactions similar to those performed past mitochondria in animals. The double membrane structure of chloroplasts is also reminiscent of mitochondria. The inner membrane encloses an area chosen the stoma, which is analogous to the matrix in mitochondria and houses DNA, RNA, ribosomes, and different enzymes. Chloroplasts, however, comprise a third membrane and are generally larger than mitochondria.
The Cell Wall
Another structural difference between in institute cells is the presence of a rigid cell wall surrounding the cell membrane. This wall can range from 0.ane to x micrometers thick and is composed of fats and sugars. The tough wall gives added stability and protection to the plant cell.
Vacuoles
Vacuoles are large, liquid-filled organelles found only in establish cells. Vacuoles tin can occupy upward to 90% of a cell's volume and accept a unmarried membrane. Their main part is as a space-filler in the prison cell, but they can also fill digestive functions similar to lysosomes (which are as well present in plant cells). Vacuoles incorporate a number of enzymes that perform various functions, and their interiors tin exist used as storage for nutrients or, as mentioned, provide a place to degrade unwanted substances.
