A Diagram of a Plant Cell
Although plant cells differ greatly they all have similar eukaryotic organisation. It can be seen in the diagram of a plant cell that the cells are made up of many different parts; these are known as organelles. These are described in more detail below.
Parts shown in the Plant cell diagram
Below is a list of the main parts shown in the plant cell diagram and the roles that they play in the cell.
Nucleus - contains the genetic information of the cell
Nuclear envelope - double membrane surrounding the nucleus
Perinuclear space - space between the two membranes of the nuclear envelope
Nucleolus - site of ribosome synthesis - densely granular
Ribosomes - site of protein synthesis
Rough Endoplasmic Reticulum - covered in ribisomes - lamellar
Smooth Endoplasmic Reticulum - tubuler
Golgi Body - synthesis and secretion of polysaccharides
Chloroplast - Site of Photosynthesis
Granum (Grana) - stacked thyalkoid membranes
Stroma - fluid matrix surrounding the thylakoids
Thylakoid - Membrane found in the chloroplast
Intercellular air space - gap between cells
Cell Wall - Rigid structure surrounding plant cells, not present in animal cells
Middle lamella- protein rich cement between adjacent plant cell walls
Primary Cell Wall - earliest created cell walls - usually thin - found in young growing cells
Secondary Cell Wall - Formed in older cells as part of the differentiation process
Plasma Membrane - Outer boundary of the cell
Mitochrondrian - Energy producing organelle - respiration
Peroxisome- Removes hydrogens from substrates - present in photosynthetic cells - has a crystalline core
Oleosome - Oil lipid storage (seeds)
Vacuole - Water filled part of the cell that may represent up to 90% of the total plant cell - also contains ions, sugars, secondary metabolites and enzymes
Tonoplast - Membrane surrounding the Vacuole
