Chapter 1 Flashcards
In biology, the smallest unit that can processes; cells are covered by a membrane and have DNA and cytoplasm
Cell
A phosphilipid layer that covers a cells surface; acts as a barrier between the inside of a cell and the cells envirenment
Cell membrane
One of the small bodies in a cells cytoplasm that are specialized to perform a specific function
Organelle
In a eukaryotic cell, a membrane bound organelle that contains the cells 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: Eukaryotas in clued animals, plants, and fungi, but not archaebacteria or eubacteria
Eukaryote
A rigid structure that surrounds the cell membrane and provides support to the cell
Cell Wall
Cell organelle composed of RNA and protein: the site of protein synthesis
Ribosomes
a system of membranes that us found in a cell’s cytoplasm and that assists in the production, processing and the transport of proteins and the production of lipids
Endoplasmic Reticulum
In eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration
Mitochondrion
Cell organelle that helps make and packages materials to be transported out of the cell
Golgi Complex
A small cavity or sac that contains material in a eukaryotic cell
Vesicle
A cell organelle that contains digestive enzymes
Lysosome
a group of similar cells that perform a common function
Tissue
A collection of tissues that carry out a a specialized function of the body
Organ
