Revision Flashcards
Magnification
the action of magnifying something or the process of being magnified.
Eukaryortic cell
Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals.
Phloem
Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers). Other molecules such as proteins and mRNAs are also transported throughout the plant
Lysis
the disintegration of a cell by rupture of the cell wall or membrane.
Resolution
a firm decision to do or not to do something.
Prokaryotic cells
Prokaryotic cells are cells that do not have a true nucleus or membrane-bound organelles. Organisms within the domains Bacteria and Archaea have prokaryotic cells, while other forms of life are eukaryotic. However, organisms with prokaryotic cells are abundant and make up much of Earth’s biomass.
Diffusion
Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.
Plasmid
a genetic structure in a cell that can replicate independently of the chromosomes, typically a small circular DNA strand in the cytoplasm of a bacterium or protozoan. Plasmids are much used in the laboratory manipulation of genes.
IAM triangle
The triangle that tells us the multipication and division of size
Dilute turgid
A plant cell in a dilute solution (higher water concentration than the cell contents) Water enters the cell by osmosis. The cytoplasm pushes against the cell wall and the cell becomes turgid.
