Cellular Structures

HideShow resource information
Cell Membrane
The membrane that surrounds every cell, forming the selectively permeable boundary between the cell and its environment. It is made up of a double layer of phospholipids with embedded proteins.
1 of 23
Cell Wall
A membrane of the cell that forms external to the cell membrane whose main role is to give cells rigidity, strength and protection against mechanical stress. It is found in cells of plants, bacteria, archaea, fungi, and algae.
2 of 23
Centrioles
Organelles from which the spindle fibres develop during cell division in animal cells.
3 of 23
Chloroplast
An organelle found in plants, which contains chlorophyll and is responsible for photosynthetic activity in the plant.
4 of 23
Chromatin
Material staining dark red in the nucleus during interphase of mitosis and meiosis. Consists of nucleic acids and proteins. Chromatin condenses into chromosomes during prophase of nuclear division.
5 of 23
Cytoplasm
Where the functions for cell expansion, growth, metabolism, and replication are carried out.
6 of 23
Cytosol
The liquid component of the cytoplasm surrounding the organelles and other insoluble cytoplasmic structures in an intact cell where a wide variety of cell processes take place.
7 of 23
Golgi Body
Eukaryotic, membrane-bound organelle. Modifies proteins (made at the Rough ER) into glycoproteins, packages proteins for secretion outside cell and makes lysosomes.
8 of 23
Intracellular Space
Space inside the cell
9 of 23
Lysosome
Membrane-bound vesicles pinched off the Golgi body. Usually contain digestive enzymes.
10 of 23
Microfilaments
Filament of the cytoskeleton found in the cytoplasm of eukaryotic cells. Anchors the centrosomes at opposite poles of the cell during mitosis and aids in the contraction of the cell during cytokinesis
11 of 23
Microtubules
Components of the cell cytoskeleton involved in mitosis, cytokinesis and movement of vesicles within cells.
12 of 23
Mitochondria
Organelles found in cells in which most of the ATP synthesis occurs. It is the site of aerobic respiration.
13 of 23
Nuclear Pore
Allows entry and exit of selected biomolecules through the nucleus.
14 of 23
Nuclear Membrane
The double membrane structure surround the nucleus in eukaryotic cells.
15 of 23
Nucleus
A large, membrane-bound organelle found in eukaryotic cells, which contains the genetic material in the form of chromosomes.
16 of 23
Nucleolus
Involved with ribosomal RNA synthesis and formation of ribosomes in eukaryotes.
17 of 23
Organelle
Structure inside a cell with a specific function.
18 of 23
Plasmodesmata
A fine strand of cytoplasm that links the protoplasm of adjacent plant cells through a thin area of cell wall called a pit.
19 of 23
Ribosome
Organelle, made of two subunits, on which proteins are synthesised inside the cell.
20 of 23
Rough Endoplasmic Reticulum
Membrane-bound flattened sacs extending from the outer nuclear membrane through the cytoplasm. Ribosomes are attached to the outer surface, and it is involved with the synthesis of proteins.
21 of 23
Smooth Endoplasmic Reticulum
Membrane-bound flattened sacs extending from the outer nuclear membrane through the cytoplasm. Involved with lipid metabolism or membrane formation.
22 of 23
Vacuole
Transports substances in and out of cell and between organelles.
