Parts of plant cell and their function

Answers

Nucleus - Contains genetic material, which controls the activities of the cell
Cytoplasm- Most chemical processes take place here, controlled by enzymes
Cell membrane- Controls the movement of substances into and out of the cell
Mitochondria- Most energy is released by respiration here
Ribosomes- Protein synthesis happens here

The parts of the plant cell are as follows:  

Cell wall is the outermost rigid covering of the plant cell. It is a salient feature of plant cell.  

Cell membrane or the plasma membrane is the outer lining of the cell inside the cell wall.  

Cytosol or cytoplasm is the gel-like matrix inside the cell membrane which constitutes all other cell organelles.

Nucleus is the control center of the cell. It is a membrane bound structure which contains the hereditary material of the cell - the DNA  

Chloroplast is a plastid with green pigment chlorophyll. It traps light energy and converts it to chemical energy by the process of photosynthesis.

Mitochondria carries out cellular respiration and provides energy to the cells.

Vacuoles are the temporary storage center of the cell.

Golgi body is the unit where proteins are sorted and packed.

Ribosomes are structures that assemble proteins.

Endoplasmic reticulum are membrane covered organelles that transport materials.

Cell wall: The cell wall is a rigid layer that surrounds the plant cells. It is made up of cellulose.  Cell wall is a characteristic feature to cells of plants. Plant cell walls are primarily made up of cellulose. Plant cell wall consists of three layers: the primary cell wall, secondary cell wall and the middle lamella. It is located outside the cell membrane whose main function is to provide rigidity, strength, protection against mechanical stress and infection. Cell wall is made up of cellulose, pectins,glycoproteins, hemicellulose and lignin.

Cell membrane: It is the outer boundary of the cell, it encloses the cytoplasm and the organelles of the cells. In plants cells it is inside the cell wall. The cell membrane is semi permeable, allowing only specific substances to pass through and blocking others.

Chloroplasts: It is an elongated or disc-shaped organelle containing chlorophyll. They have two membranes and have structures that look like stack of coins. They are flattened structures which contain chemical chlorophyll. The process of photosynthesis occurs in this region of the plant cell. The chlorophyll is a green pigment that absorbs energy from sunlight to make food for the plants by converting light energy into chemical energy.


Cytoskeleton: It is a network of fibers made up of micro-tubule and micro-filament. They maintain the shape and gives support to the cell.

Microtubules: They are hollow cylinder like structures found in the cytoplasm of the cells. Its function is transport and structural support.

Microfilaments: Microfialments are solid rod like structures whose primary function is structural support.

Plasmodesmata: They are microscopic channels which traverse the cell walls of plant cells and enables transport and communication between them.

Vacuole: Vacuoles are known as cells storage center. Plant cells have large membrane bound chamber called vacuole. Its main function is storage. Vacuoles are found in the cytoplasm of most plant cells. They are membrane bound organelles, they perform functions of secretion, excretion and storage.  

Tonoplast: A vacuole that is surrounded by a membrane is called tonoplast.

Plastids: Plastids are storage organelles. They store products like starch for synthesis of fatty acids and terpenes.  

Chromoplast: They are plastids responsible for pigment synthesis and storage. They are found in photosynthetic eukaryotic species. They are found in colored organs of plants like fruits and flowers.  

Ribosomes: Ribosomes are smallest and the most abundant cell organelle. It comprises of RNA and protein. Ribosomes are sites for protein synthesis. They are found in all cells because protein are necessary for the survival of the cell. The ribososomes are known as the protein factories of the cell.  

Lysosome: Lysosome contain digestive enzymes. They digest excess or worn out organelles, food particles and any foreign bodies.

Microbody: It is a single membrane bound organelle that comprises of degradative enzymes

Cytoplasm: It is a gel-like matrix inside enclosed by the cell membrane. The cytoplasm supports cell organelles and also prevents the cell from bursting or shrinking.

Nucleus: It is the control center of the cell. It is bound by a double membrane known as the nuclear envelope. It is a porous membrane, it allows passage of substances and is a distinctive characteristic of the eukaryotic cell. Most of the genetic material is organized as multiple long linear DNA molecules. The nucleus directs all the activities of the cell and also help in protein formation.

Each part of the cell has a specialized function. These structures are called organelles. This diagram shows the various parts of a plant cell. Specialized structures in plant cells include chloroplasts, a large vacuole, and the cell wall.

Explanation:its correct

All living things are made up of cells. The structures of different types of cells are related to their functions. Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. ... Dissolved substances pass into and out of cells by diffusion.

Plasma membrane- encloses the cell and separates what is inside it from its invironment
