∙ 12y agoPlant cells like animal cells are eukaryotic, i.e. they contain membrane bound nuclei and cell organelles. A plant cell differs from an animal cell in having certain distinctive structures - cell wall, vacuoles, plasmodesmata and plastids. On the contrary, plant cells lack centrioles and intermediate filaments, which are present in animal cells. Despite these, plant and animal cells share several similarities in structure, parts and their roles.
Different Parts of a Plant Cell
Plant cells are classified into three types, based on the structure and function, viz. parenchyma, collenchyma and sclerenchyma. The parenchyma cells are living, thin-walled and undergo repeated cell division for growth of the plant. They are mostly present in the leaf epidermis, stem pith, root and fruit pulp. Mature collenchyma cells are living, and provide stretchable support to the plant. Lastly, sclerenchyma cells (e.g. fiber cells) are hard, non-living and give mechanical support to plants. Now, let us see the different parts of a plant cell with their significant roles.
Cell Wall
Cell wall is the outermost tough and rigid layer, which comprises cellulose, hemicellulose, pectin and at other times, lignin. As expected, it remains connected with the cell walls of other cells. The prime functions of cell wall are protection, giving structural support and helping in the filter mechanism.
Cell Membrane
Cell membrane, also called plasma membrane, is present inside the cell wall and surrounds the cytoplasm. It connects the intracellular components (organelles and cytoplasm) with the extracellular environment, and helps in protection and transportation. The cell membrane is permeable to specific substances only.
Plasmodesmata
Plasmodesma (plural plasmodesmata) is a small opening, which connects plant cells with each other. Present only in some types of algal cells and plants cells, this connecting channel enables transport of materials and allows communication between the cells. In a single plant cell, about 1,000-100,000 plasmodesmata are present.
Nuclear Membrane
The nuclear membrane and the nuclear envelope mean one and same thing. As the name reveals, it is the outer covering of the nucleus. It separates the cytoplasmic contents from the nuclear contents. Nonetheless, minute pores (nuclear pores) are present for exchanging materials between the nucleus and cytoplasm.
Nucleus
Nucleus is a specialized organelle, which contains the plant's hereditary material i.e. DNA (Deoxyribonucleic Acid). Inside the nucleus, a dense, spherical body called nucleolus is present. The nucleus contains structures, which regulates the cell cycle, growth, protein synthesis and reproductive function.
Vacuole
Vacuoles are large membrane-bound compartments, which store water and compounds. They function as storage, excretory and secretory organelles. The membrane surrounding a vacuole is called tonoplast. A mature plant cell has a single vacuole at the near center of the cell (central vacuole), which contributes to about 30-80 percent of the cell's volume.
Cytoplasm
Cytoplasm is filled up by cytosol, which is a gelatinous and semitransparent fluid. All the organelles of plant cell are present in this cytoplasm. This part of the plant cell is the site for cell division, glycolysis and many other cellular activities. Also, the cytoskeleton elements (microtubules and microfilaments) are present in the cytosol.
Plastid (Chloroplast)
Plastids are organelles responsible for photosynthetic activity, manufacturing and storage of chemical compounds in plants. Chloroplast is an important form of plastid containing chlorophyll pigment, which helps in harvesting light energy and converting it to chemical energy. Likewise, chromoplast and other plastids are present in a plant cell.
Mitochondria
Mitochondria (singular mitochondrion) are oblong shaped organelles, which are also known as 'the powerhouse of the cell'. They are responsible for breaking down complex carbohydrate and sugar molecules to simpler forms, which the plants can use. Other than this, mitochondria are crucial for cell signaling, cycle, division, growth and death.
Endoplasmic Reticulum
The endoplasmic reticulum (ER) organelle plays a major role in manufacturing and storage of chemical compounds, like glycogen and steroids. It is also involved in translation and transportation of protein. ER is also connected to the nuclear membrane, so as to make a channel between the cytoplasm and the nucleus.
Golgi Apparatus
Golgi apparatus also known as golgi complex and golgi body. It is an organelle responsible for processing of macromolecules (like carbohydrates, proteins and fats) and packaging them into membrane-bound vesicles for transportation purposes. Golgi bodies are present near to the nucleus of the plant cell.
Ribosome
Ribosomes are organelles, which are made up of 60% RNA (Ribonucleic Acid) and 40% protein, and play an important role in protein translation. It won't be wrong to say that the main site of protein synthesis is ribosome. Endoplasmic reticulum having ribosomes is referred to as rough endoplasmic reticulum (RER).
Microbodies
Microbodies are single, membrane-bound, globular shaped organelles, which are found in the cytoplasm. They range in size from 0.5-1 micrometer, and contain degradative enzymes. Many kinds of microbodies are present in a plant cell, of which the two most common types are peroxisomes and glyoxysomes.
Microtubules
Microtubules are straight, hollow, tubular cylinders, which are major elements of the cytoskeleton. These plant cell structures are involved in synthesizing cell wall. Function wise, they are crucial for structural support, cell division and transport of vesicles. Microtubules in a plant cell are simpler, as compared to those of an animal cell.
Microfilaments
Microfilaments are thin, filament like structures found in the cytosol, which contain actin subunits. These along with the microtubules make up the cytoskeleton of plants cells. Similar to the microtubules, the microfilaments are responsible for giving structural support, flexibility and shape to the cell.
In the overall functioning of a plant cell, the above cell parts coordinate in a specific manner. As you have seen, lysosomes are absent in plant cells. While vacuole is large and single in a plant cell, the animal cell houses smaller vacuoles in larger numbers. Likewise, for understanding the differences between plant and animal cells, you can study the cells separately along with the types of organelles present in them.

∙ 11y agoThe plant cell is made out of a cell wall, cell membrane, a vacuole, a nucleus, chloroplasts and cytoplasm. The cell wall is a fully permeable membrane, made out of cellulose. It give the cells it rectangular shape. The cell membrane is a partially permeable membrane, that only allows to let the smaller particles in and out. The vacuole stores sap and nutrients. A nucleus is the main organ. It controls all activities in the cell and also helps in the reproduction of the cell. Chloroplasts contains chlorophyll, that traps sunlight for the production of food from the plant, otherwise known as photosynthesis. Cytoplasm is a jelly like substance that allows chemical reactions to take place.

Unique structure to cell plants?
A plant cell contains more structures than an animal cell which just contains a nucleus, cytoplasm and a cell membrane but may also contain small vacuoles. A plant cell contains all of these things aswell as a cell wall, chloroplasts and a vacuole
What happens when plant is put into water?
If a plant cell is placed in fresh water, there will be a net movement of water into the cell - because the solute concentration inside the cell is greater than outside. This occurs because the system is attempting to reach equilibrium (where the concentrations inside and outside are equal). Unlike an animal cell, a plant cell will not burst when excess water enters the cell. This is because the cell wall helps the plant cell maintain its structure.
What is the main purpose of a cell wall in a plant cell?
The main purpose of the cell wall is too protect the cell from too much liquid being diffused in. It also helps keep the cells rectangular structure.
Where is the cell membrane located in a plant cell?
The cell wall is the outer-most layer, found outside the cell membrane. Animal cells only have a cell membrane, not a cell wall. Plant, bacteria, fungi and algal cells usually have a cell wall, as well as some archaea.
