organelles
little cell structures that have specific functions and are found in Eukaryotes
cell membrane
cells security system, surrounds and protects the cell, controls what enters and exits the cell
cytoplasm
gel-like substance inside the cell, where cell processes (chemical reactions) occur, 80% water
cell wall
tough structure that surrounds and protects plant cells, gives cells shape, made of cellulose
nucleus
control center of the cell, contains directions for the entire cell, DNA is found here, surrounded by a nuclear membrane
cholorplast
green organelle, in plant cells, photosynthesis, captures energy from the sun to make glucose
mitochondria
cell energy dam, stores and releases cell's energy, "powerhouse"
ribosomes
protein factories, make proteins, some float freely in the cytoplasm and others are attached to the ER
endoplasmic reticulum
cell's railroad track, moves material around in the cell, smooth-no ribosomes, rough-has ribosomes
golgi body
cell's post office, sorts and packages proteins into vesicles, vesicles deliver substances in the cell and also attach to the cell membrane to release materials to the outside
nucleolus
manufactors the proteins that make up the ribosomes, found in the nucleus
lysosome
cell's landfill, digest food molecules, cell wastes, and worn out cell parts
vacuole
temporarily stores food, water, waste; rather large in plan cells (vacuum stores dirt-like vacuole)
cytoskeleton
framework for the cell; helps to maintain shape or change shape of cell
tissue
a group of cells working together to perform a particular function
organ
two or more tissues working together to perform a function
