PlantCell Organelle and Function, All Cell Organelles and Functions mine

cell membrane

determines what goes in/out of cell

nuclear membrane

decides what goes into and out the nucleus

nucleus

directs cell activities

ribosome

makes proteins

cell wall

supports and protects the plant cell

chloroplast

photosynthesis uses sunlight to make sugar

vacuole

help plants maintain shape storage, digestion, and waste removal

lysosome

disposal of the cell

smooth endoplasmic reticulum

transports proteins and breaks down drugs in the cell; does not contain ribosome

rough endoplasmic reticulum

covered in ribosomes which make the proteins that are transported

mitochondria

"powerhouse" of cell; produces energy from sugar

Golgi body

processes and packages proteins and lipids; moves materials within the cell and out of the cell in small sac

cytoskeleton

Network of protein fibers, is the structural framework for cell shape

centrosome

Made from two centrioles. Organises microtubles and provides cell structure

nucleus

regulates all cell activity, composed of DNA

cell/plasma membrane

composed of phospholipid bilayer. Protects the cell from its surroundings

nucleolus

made up of proteins and RNA. Rewrites RNA and combines it with proteins

chromosomes

Thread-like structures made up of DNA. Provides organism with genetic information.

golgi apparatus

Stacks of flattened membranous sacs called cisternae. modify's and sorts proteins for secretion

lysosomes

Membrane sac of enzymes. Digests excess or worn-out organelles.

smooth ER

ER which has no ribosomes on it. Regulates and releases calcium ions and processes toxins

ribosomes

Two subunits made of RNA and proteins. Make proteins

cilia

Organelles that extend from the surface of nearly all mammalian cells. They move a cell or group of cells or to help transport fluid or materials past them

flagella

whip, tail like appenage that propels the cell along

chromatin

efficiently package DNA into a small volume

centriole

Small set of microtubules arranged in a certain way. Help in the formation of the spindle fibers.

cytoplasm

The material in the cell. Holds the internal components of cells in place.

mitochondria

Bound by a double membrane. Produces ATP through respiration

cell wall

composed of cellulose. A filtering mechanism and pressure vessel to prevent over-expansion.

central vacuole

Large membrane-bound vesicle. involved with storage, cell growth, digesgtion, waste disposal.

rough ER

Ribosome covered ER. responsible for the assembly of proteins, translation.

chloroplast

two membranes around a fluid stroma which contain thylakoid stacked into grana. involved in photosynthesis

(transport) vesicle

fluid enclosed by lipid bilayer. moves molecules between locations inside the cell

fimbrae

finger-like projections that allow bacteria to stick to the environment

pili

appendages that allow bacteria to attach to each other and to transfer DNA

cytoplasm

supports and protects cell's organelles
