Cellular life on Earth is a beautiful phenomenon providing the oxygen you breathe and the food you eat. You probably haven’t seen that much plant life, though. Luckily, you can find a lot of plant cell examples on the internet.

Cell

The plant cell is rectangular and comparatively larger than the animal cell. Even though plant and animal cells are eukaryotic and share a few cell organelles, plant cells are quite distinct when compared to animal cells as they perform different functions. Some of these differences can be clearly understood when the cells are examined under an electron microscope.

Parenchyma cells play a significant role in all plants. They are the living cells of plants, which are involved in the production of leaves. They are also involved in the exchange of gases, production of food, storage of organic products and cell metabolism. These cells are typically more flexible than others because they are thinner.

Animal

A plant cell, similar to an animal cell, is eukaryotic. Eukaryotic cells are characterized by the presence of organelles, particularly the nucleus, as opposed to prokaryotic cells that lack them. Although plant cell and animal cell are similar in this regard they have recognizable structural differences. A plant cell has a rigid cell wall that is absent in an animal cell. There is also a central vacuole that occupies much space in a plant cell. In an animal cell, the vacuoles are numerous but small. Plant cells have many chloroplasts whereas animal cells lack them. Chloroplasts are key organelles in photosynthesis. Thus, plants are capable of making their own food directly from inorganic sources whereas animals rely on available food from organic sources. They also differ in how a cell divides. A plant cell divides by forming a cell plate between two daughter cells during the latter phase of cell division. In contrast, an animal cell forms a cleavage furrow.

Like the fungi, another kingdom of eukaryotes, plant cells have retained the protective cell wall structure of their prokaryotic ancestors. The basic plant cell shares a similar construction motif with the typical eukaryote cell, but does not have centrioles, lysosomes, intermediate filaments, cilia, or flagella, as does the animal cell. Plant cells do, however, have a number of other specialized structures, including a rigid cell wall, central vacuole, plasmodesmata, and chloroplasts. Although plants (and their typical cells) are non-motile, some species produce gametes that do exhibit flagella and are, therefore, able to move about. (Source: micro.magnet.fsu.edu)
