Surrounds all cells, regulates the passage of materials in and out of the cell.
Cell Wall
Found only in plants, it is a structure that surrounds and protects the plant cells-- supports and provides shape-- made of cellulose (polysaccharides)
Nucleus
Large, usually circular organelle that carries Chromosomes and controls cell division. Control center of cell.
Nuclear Membrane
Surrounds Nucleus-- controls movement of material in and out of Nucleus.
Nucleolus
Center of Nucleus. Makes Ribosomes.
Chromatin
Fine strands of DNA found in the Nucleus.
Chromosome
Chromatin that has thickened for cell reproduction.
Cytoplasm
A fluid that takes up space between organelles. Filled with microtubules and filaments that hold the structure for the cell. Jelly-like.
Vacuoles
Storage sacs of the cell-- hold water and food.
Ribosomes
Site where proteins are made (protein factory). Made of RNA. DNA instructs ribosomes which proteins to make.
Endoplasmic Reticulum
Two types: Rough and smooth.
Involved with the transport of proteins.
Often called protein plumbing.
Golgi Bodies
Takes/transports vesicles from the Endoplasmic Reticulum then moves them outside of cell.
Layered trash sacs in cell-- waste and proteins.
Lysosomes
Filled with enzymes-- break down proteins for digestion (breaks down proteins for cell structure)
Suicide sacs-- if one bursts, it will digest itself.
Mitochondria
Takes fuel and turns it into energy for the cell. (Location for cellular respiration).
Cristae
Folded surfaces inside Mitochondria that increase work area in less space.
Plastids
Only found in plants. Stores pigments. Chloroplasts make plants green (chlorophyll)
Cilia
Hair-like projections on cell membrane that help it move.
