Cell Organelles

science grade 7

Cell membrane a covering that surronds the cell and controls materials going in and out
nucleus controls the cells activities and directs protein manufacturing in the cell. holds the chromosomes made of DNA and is surronded by a nucleur membrane
chromosomes made of DNA and carries the blue print for all of the cells activities
cytoplasm material between organelles, jelly-like substance that moves food and water around the cell
cytoskeleton a web of protein serves as a muscle and skeleton
endoplasmic reticulum tube-like canals(rouds)thatransport protein around the cell. rough ER is covered with ribosomes, smooth ER makes lipids and breaks down toxic materials
ribosomes protein making factories, frequently attached to endoplasmic reticulum, but can also float freely in the cytoplasm
golgi complex package protein to send to other places within and out of the cell. Hormones and enzymes are packaged here as well
mitchondria power house of the cell. sugar is broken down and with oxygen, energy is stored as ATP and released when needed
Vacuoles stores water, food, and waste until it is removed from the cell. Also aids in digestive enzymes in a plant cell
lysossomes contain digestive enzymes that break down food and protect the cell from foreign invaders (mainly found in animal cells)
Chloroplasts PLANT CELLS ONLY! green organelles that contain chlorophyll. the lace where photosynthesis takes place
Cell wall PLANT CELLS ONLY! strength and structure to cell. Made of cellulose, a non-living material, cell membrane is inside cell wall
