Term
cell membrane-
Definition
The thin structure made mostly of proteins and lipids(fats) that encloses the cytoplasm and nucleus of a plant and animal cell. Controls what enters and leaves the cell.
Term
Cell wall
Definition
The stiff structure outside the cell membrane in a plant, provides support for the cell.
Term
Nucleus
Definition
The control Center for most of a cells activities.
Term
Nucleic Acid-
Definition
Molecules that carry instructions for cell process in nucleus.transport through the nuclear membrane.
Term
Cytoplasm-
Definition
mostly water 80% water, expels waste through membrane. a jelly like susstance that makes up all living material in a cell except the nucleus. Supports organelles
Term
Mitochondria-
Definition
An organelle that produces energy in a cell.
Power house of a cell
Release energy in stored in food
Energy to carry out life process
Term
Ribosomes-
Definition
An organelle that produces protein for the cell
Some attached to the Endoplasmic reticulm.
Cell use protein for growth,repair,and control.
Term
homeostasis
Definition
controls internal enviroment
Term
Endoplasmic reticulm-
Definition
An organelle that transports materials throughout the cell.
made of membranes network of tubes and canals that run throughout the cytoplasm.
Term
2 types of Endo. Reticulm
Definition
rough-has ribosmes
smooth- no ribosomes
Term
Golgie Bodies
Definition
An organelle that manufactures and moves materials within a cell.
center of manufactureing and shipping
Alters Materials
Transport by ER before transports to other parts of a cell.
Term
lysosomes-
Definition
An organelle that brekas down food, molecules,waste products.and old cells.
Contains powerful chemicals to breakdown large food into smaller molecules.
Breakdown waste products and old cells. "Garbage Collectors"
Term
Vaculoes-
Definition
An organelle that stores water, food, and watse in a cell and helps get rid of wastes.
Storage
Large depending on need.
Term
Chloroplasts-
Definition
An organelle in plant cells that contains Chlorophyll.
Green
Oval shaped
Chlorophyll traps energy.
Term
Same in Plants and animal cells
Definition
Cytoplasm,Mitochondrian, Nuclear membrane,endoplasmic reticulm, nucleus, ribsome, golgi bodi,cell membrane,vacule.
Term
just in plants
Definition
cell wall, chlororplast
