Cell Theory Flashcards
(20 cards)
In Biology, the smallest unit that can perform all life processes; Cells are covered by a membrane and have DNA and cytoplasm.
cell
In a eukaryotic call, a membrane-bound organelle that contains the cell’s DNA and that has a role in processes such as growth, metabolism, and reproduction.
Nucleus
Inside The cell is a fluid. This fluid and almost all of its contents are called?
Cytoplasm
A phospholipid layer that covers a cell’s surface; Acts as a barrier between the inside of a cell’s environment.
Cell Membrane
A rigid structure that surrounds the cell membrane and provides support to the cell.
Cell Wall
In Eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration.
Mitochondria / Mitochondrion
They are organelles in plant and algae cells in which photosynthesis takes place; They have two membranes and their own DNA.
Chloroplast
Cell organelle that helps make and package materials to be transported out of the Cell.
Golgi complex
A system of membranes that is found in a cell’s cytoplasm and that assists in the production,processing, and transport of proteins and in the production of lipids.
Endoplasmic reticulum
Cell organelle composed of RNA and protein; the site of protein synthesis.
Ribosome
A cell organelle that contains digestive enzymes.
Lysosome
The organelle that stores water and other materials.
Vacuole
One of the small bodies in a cell’s cytoplasm that are specialized to perform a specific function.
Organelle
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 group of similar cells that preform a common function.
Tissue
A collection of tissues that carry out a specialized function of the body.
Organ
A group of organs that work together to perform body functions.
Organ system
A living thing; anything that can carry out life processes independently.
Organism
The arrangement of parts in an organism.
Structure
