quiz, Naming cell parts Flashcards
Nucleus
- controls most cell processes
- contains the hereditary material DNA
- Contains Chromatin and Chromosomes
Nuclear membrane/nuclear envelope
- membrane enclosing the nucleus.
- it’s dotted with nuclear pores that allow materials to move in and out of the nucleus
Nucleolus
ribosome production
Ribosomes
- produces proteins
- follows specific coded instructions that come from the nucleus
Endoplasmic Reticulum
- components of the cell membrane and proteins are made
- transport materials
- two types (rough er and smooth er)
cytoplasm
- jelly like material that organelles are floating in.
- contains important dissolved materials that the cell needs
vacuole
- stores material within a cell
- plant cells contain large vacuole
cell membrane
- fluid modle,
- selectively permeable
- phospholipid bilayer: controls what goes in and out of the cell (some parts hydrophobic and others hydrophilic)
cell wall
- used for support and protection for cells
- found in many organisms such as: plants, fungus, algae, and many prokaryotes
- found outside the cell membrane
what is a plants cell wall mostly made of
cellulose
mitochondria
the “power house” of a cell
- converts food into high-energy compounds the cells can use (this is ATP)
chloroplasts
- use energy from the Sun to make energy-rich molecules
- photosynthesis occurs here
cytoskeleton
network of protein filaments that gives the cell its shape-also involved in cell movement
-made up of microtubules and microfilaments
what are microtubules
hollow tubes of protein for cell shape and organelle movement
what are microfilaments
long thin fibers for movement and support
