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
Chromatin
granular material visible within the nucleus
Chromosomes
Chromatin that condenses when cells are going to divide
golgi Apparatus
- package and distributes materials
- adds carbs and lipids to proteins
- makes vesicles for transport
lysosomes
- filled with enzymes
- break down substances (even old organelles)
- “suicide Sac”
what is rough er
ribosomes stud its surface
smooth er
attach carbs and lipids to proteins
