Chapter 1 the Diversity of Cells Flashcards
In Biology, the smallest unit that can perform all life processes; Cells are covered by a membrane and have DNA and cytoplasm
Cell
A phospholipid layer that covers a cell’s surface; acts as a barrier between the inside of a cell and the cell’s enviroment
Cell Membrane
One of the small bodies in a cell’s cytoplasm that are specialized to perform a specific function
Organelle
In a eukaryotic cell, a membrane-bound organelle that contains the cell’s DNA and that has a role in processes such as growth, metabolism, and reproduction
Nucleus
An organism, that consists of a single cell that does not have a nucleus
Prokaryote
An organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include animals, plants, and fungi, but not archaebacteria or eubacteria
Eukaryote
A microscopic animal
Animalcules
In biology, cell theory is a scientific theory which describes the properties of cells
Cell theroy
As the cube size increases or the cell gets bigger , then the surface area to volume ratio - ratio decreases
Surface area-to-volume ratio
The material or protoplasm within a living cell, excluding the nucleus
Cytoplasm
A bacterium of a large group typically having simple cells with rigid cell walls
Eubacteria
A minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells.
Ribosomes
A microorganism, especially an archaean, that lives in conditions of extreme temperature
Extremophiles
