Containing cells that have a nucleus and other membrane-bound organelles. DNA is packed into chromosomes.
Eukaryote
1 of 22
Single-celled organism that doesn't have membrane-bound organelles. DNA free in the cytoplasm.
Prokaryote
2 of 22
Microscopic double layer of lipids and proteins forming the boundary of cells or organelles.
Membrane
3 of 22
Any number of organised or specialised structure within a living cell.
Organelle
4 of 22
An individual animal, plant, or single-celled life form
Organism
5 of 22
The action of magnifying something or the process of being magnified OR An measure of the ability of a lens or other optical instruments to magnify, expressed as the ratio of the size of the image to that of the object.
Magnification
6 of 22
The shortest distance between two points on a specimen that can still be distinguished by the observer or camera system as separate entities.
Resolution
7 of 22
An auxiliary technique used in microscopy to enhance contrast in the microscopic image.
Staining
8 of 22
The smallest structural and functional unit of an organism, which is typically microscopic and consists of cytoplasm and a nucleus enclosed in a membrane.
Cell
9 of 22
Any of a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair,
Protein
10 of 22
The process by which amino acids are linearly arranged into proteins through the involvement of ribosomal RNA, transfer RNA, messenger RNA, and various enzymes.
Protein Synthesis
11 of 22
A bubble-like membranous structure that stores and transports cellular products, and digests metabolic wastes within the cell; an intracellular membranous sac that is separated from the cytosol by at least one lipid bilayer
Vesicles
12 of 22
A minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.
Ribosome
13 of 22
A complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
Golgi Apparatus
14 of 22
A microscopic membrane of lipids and proteins which forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and regulates the passage of molecules in and out of the cytoplasm
Plasma Membrane
15 of 22
A protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm
Nuclear Pore
16 of 22
A microscopic membrane of lipids and proteins which forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and regulates the passage of molecules in and out of the cytoplasm
Plasma Membrane
17 of 22
A protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm
Nuclear Pore
18 of 22
A microscopic membrane of lipids and proteins which forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and regulates the passage of molecules in and out of the cytoplasm
Plasma Membrane
19 of 22
A protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm
Nuclear Pore
20 of 22
A network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (SER) or studded with ribosomes (RER) involved in the transport of materials.
Endoplasmic Reticulum
21 of 22
A subtype of RNA that carries a portion of the DNA code to other parts of the cell for processing and is created during transcription.
mRNA
