1.1 The Diversity of Cells Flashcards
in biology, the smallest unit that can preform 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 environment
cell membrane
one of the smallest bodies in a cells cytoplasm that are specialized to preform 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 animal plants, and fungi, but not archaebacteria or uebacteria

animalcules
written by Schwann that states that all organisms are made of one or more cells, the cell is the basic unit of all living things.
cell theory
Hooke named the cork’s inside that looked like little boxes …
cell
The ratio of cell’s outer surface area to the cell’s volume is called
surface area-to-volume ratio
The fluid inside the cell and almost all of its contents are called the
cytoplasm
cells with no nucleus
prokaryotic cells
cells that have a nucleus
eukaryotic cells
one of the groups prokaryotic cells are classified into
eubacteria
one of the groups prokaryotic cells are classified into
