Plant cell structure and functions

Nuclear pores in the nuclear membrane enable various substances, such as nutrients and waste products, to pass into and out of the nucleus. It finishes modifying proteins and fats from the ER and prepares them to be sent out to other parts of the cell or even outside of the cell.

Cell wall is a characteristic feature to cells of plants. Within the inner membrane is a protein-rich substance known as stroma, it is embedded in a membrane system. The constituents of the cell are suspended in the cytoplasm or cytosol.

It is a gel-like matrix inside enclosed by the cell membrane. These can include proteins, energy compounds, and nutrients.

Thought to have evolved from the green algae, plants have been around since the early Paleozoic era, more than million years ago. May 16, We all are well aware of the importance of cells in controlling the metabolism and other life processes which help sustain life. Florida State University The plasmodesmata are small tubes that connect plant cells to other plant cells and it connects the ER to those other plant cells as well to aid in transport beyond the plant cell.

The absence of color is due to the lack of pigments. Ribosomes are sites for protein synthesis. This is because a plant cell contains all the vital components it needs to function and maintain its particular structure and survive.

It is located outside the cell membrane whose main function is to provide rigidity, strength, protection against mechanical stress and infection. Rough Endoplasmic Reticulum RER Rough endoplasmic reticulum is the site of protein synthesis which takes place within the ribosomes attached to the surface of the RER as well as storage of proteins and preparation for secretion of those proteins.

The quantity of mitochondria within cells varies with the type of cell. Notably the presence of a more rigid cell wall and the modification to photosynthesize which requires chloroplast. Peroxisomes are spherical organelles that contain enzymes used to break down toxins that hurt the cell.

These organelles provide the energy required for all cellular activities by breaking down complex carbohydrates prepared during photosynthesis glucose to energy.

BiologyWise Staff Last Updated: The shape of the cholorplast varies, it may be spheroid or ovoid or discoid. Along with these, there are other essential cell organelles that contribute in the proper working of the cell.Feb 23,  · Plant cells are a eukaryotic cell that varies in several fundamental factors from other eukaryotic organisms.

Both plant and animal cells contain nucleus along with similar organelles.

Plant Cell Parts And Functions

One of the distinctive aspects of a plant cell is the presence of a cell wall outside the cell membrane. The unique plant cell has similar parts and functions to an animal. Plant cell parts each have their own function, from the cell wall to the chloroplast.

The plant cell is a type of eukaryotic cell mainly because of the presence of a nucleus and nuclear membrane.

Plants are autotrophic in nature owing to a special organelle―chloroplast, which helps prepare food in the form of complex carbohydrates. Plant Cell Structure is a topic within the cell biology and is included in A-Level Biology. This page includes a diagram of a plant cell together with notes about the parts of plant cells including organelles present in plant cells, such as mitochondria, chloroplasts and Golgi apparatus.

Plant Cell

These notes include links to further information about the structures and functions of the parts of plant. A plant cell also contains structures not found in an animal cell. Some of these include a cell wall, a large vacuole, and plastids.

Plastids, such as chloroplasts, assist in storing and harvesting needed substances for the plant.
