Plant cells and Animal cells

Plant and animal cells, as you know, have many differences as well as similarities. They can be distinguished by the presence of organelles in both of them. However, they are both eukaryotic cells. Plants and animals have eukaryotic cells, so their cell structures are very similar. A plasma membrane, a nucleus, cytoplasm, ribosomes, and mitochondria are all components of a eukaryotic cell. Nonetheless, there are significant differences between plant and animal cells. Wall vacuoles, chloroplasts, size, and other characteristics distinguish them. As a result, the purpose of this article is to provide you with an overview of the definitions and differences and the additional information to help you understand them better.

What is a Plant cell?

Plantae is primarily made up of multicellular eukaryotes that are autotrophic in nature. Moreover, Plant cells’ organelles, such as chloroplasts, cell walls, and vacuoles, aid in distinguishing them from animal cells. While there are many plant species that have yet to be discovered, the ones that have been identified number around 400,000.

Plant cells range in size from 10 to 100 m in most cases. The function of photosynthesis is carried out by plant cells. As a result, green plants are referred to as autotrophs. It is done because chlorophyll is present in the chloroplasts of plant cells. Cellulose is the component of the cell wall that provides support and rigidity to the cells.

Functions of Plant cells

Plant cells are the basic building blocks of plant life, performing all of the processes necessary for survival. Photosynthesis is the process by which light energy, carbon dioxide, and water are converted into food. They occur in the chloroplasts of the cell. Here are some examples of specialised plant cells:

• Collenchyma Cells – Collenchyma cells are elongated living cells with irregularly thickened main walls. They have the ability to change shape and grow in the same way that plants do. The fact that collenchyma is extremely plastic—that is, the cells can stretch and thus respond to increased organ growth—is a significant feature.

• Sclerenchyma Cells – Sclerenchyma cells are stiffer. They are the primary sustaining cells in plant regions that have reached the end of their development. Sclerenchyma cells that have reached maturity are frequently dead cells with thickened secondary walls. They also have a high cellulose content (60–80%) and are used to provide structural support to plants.

• Parenchyma Cells – Parenchyma refers to the simple permanent ground tissues that make up the majority of plant tissues, such as the soft component of the leaves and fruit pulp  and the other plant organs. They can be found in leaves and are responsible for photosynthesis, cellular respiration, and metabolic processes. They also help plants heal by storing chemicals like carbohydrates and proteins.

• Xylem Cells – This tissue helps to transport dissolved chemicals and water throughout the plant. Xylem components include tracheids, vessels, xylem parenchyma, and xylem fibres. The xylem transports water and dissolved minerals from the plant’s roots to its leaves.

• Phloem Cells – It transports photosynthesis-produced nutrients to all parts of the plant. The Phloem transports are the sugars and the amino acids dissolved in the water. The phloem carries nutrients from the leaves to the roots.

What are Animal cells?

The Kingdom Animalia contains three-fourths of all species on the planet. The human body is made up of 1014 cells that range in size from 10 to 30 m in diameter. Animal cells do not have a cell wall or chloroplasts, which distinguishes them from plant cells. The primary distinction between animal and plant cells is that animal cells are unable to generate their own nutrition. The three primary components of most animal cells are the nucleus, cell membrane, and cytoplasm.

There is a belief that cell walls vanished during evolution, resulting in the development of animal cells with more advanced cells, tissues, and organs that function more precisely.Thus, nerves and muscles help with locomotion, mobility, and other functions.

Functions of the Animal cells

To help the organism survive, all of the cells work in unison. The collection of comparable tissues will form the body’s various organs such as the heart, lungs, and so on, and these organs will collaborate to form the organ system such as the neurological system, digestive system, circulatory system, and so on. Animal cells come in a variety of forms, including:

• Skin Cells – These cells can be found in the skin’s dermal and epidermal layers. These cells are effective at preventing water loss and acting as a barrier between the inside and outside environments.

• Bone Cells – Bone cells are in charge of the development of an animal’s skeleton and bones. To maintain balance and, ultimately, control bone structure and function, bone cells communicate with one another. They also help with the movement.

• Muscle Cells – It helps to protect the body’s delicate organs. When your limbs and tissues are clustered together, they can help to organise their movement.

• Blood Cells – These cells act as transporters for hormones and nutrients in the body. They use the bloodstream to transport oxygen throughout the body.

• Nerve Cells – Specialized cells that are programmed to transmit impulses or information. Neurons are brain cells that send and receive messages. It is also known as the nerve cells. Each nerve cell is made up of the cell body, which includes the nucleus, a primary branching fibre (axon), and numerous smaller branching fibres (dendrites).
