science (20 cards)
the smallest unit that can preform all life processes, are covered by a membrane and have DNA and cytoplasm
cells
in an eukaryotic cell, a membrane-bound organelle that contains the cells DNA and that has a role in processes such as growth metabolism and reprodution
nucleus
the inside fluid of a cell.
Cytoplasm
a phospholipid layer that covers a cell’s surface; acts as a barrier between the inside of a cell and the cells environment.
Cell membrane
a rigid structure that surrounds the membrane and provides support to the cell.
cell wall
in Eukaryota cells the cell organelle that is surrounded by two membrane and that is the site of cellular respiration.
Mitochondria / Mitochondrion
contains chlorophyll. chlorophyll captures energy from the sunplants use this energy to make food
chloroplasts
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 and that assists in production, processing, and transport of proteins and in and in production of lipids.
Endoplasmic reticulum
cell oranelle composed of RNA and protein;the site of protein synthesis
Ribosome
a cell organelle that contains figestive enzymes
lysosome
it is a large vesicle
vacuole
one of the small bodies in a cell’s cytoplasm that are specialized to preform a special function
organelle
an organism that consists of a single cell that does not have a nucleus
prokaryotes
an organism made up of cells that have a nucleus enclosed by a membrane; ( ) include animals, plants,and fungi, but not archaebacteria or eubacteria
eukaryotes
a group of similar cells that preform a common function
tissue
a collection of tissue that carry out a specialized funcion of the body.
organ
a group of organs that work together to preform body functions
organ system
a living thing; anything that can carry out life processes independently
