cells chapter 5 Flashcards
plasma/cell membrane
♻️⭕️both plants and animals
- thin, flexible Barrie around cell
- controls movement in and out of cell
cell theory
- all organisms are made of 1 or more cells -can be single or multi called
- all cells carry on living activities
- new cells arise only from other living cells by cell division
cytoplasm
- jelly like substance that fills the cell
- holds the organelles
- location of chemical reactions
cell types
prokaryotic
eukaryotic
prokaryotic
- no nucleus or ribosomes, scattered DNA
- EX bacteria
eukaryotic
- nucleus with DNA and membrane bound organelles
- EX animals plants protists fungi
nucleus
♻️⭕️both
- “control center”
- membrane bound
- contains DNA
- has nucleolus
nucleolus
-produces ribosomes
endoplasmic reticulum
♻️⭕️both
- system of fluid canals enclosed my membranes
- transports materials throughout cell
ribosomes
♻️⭕️both
-make proteins
Golgi bodies/Golgi apparatus
♻️⭕️both
-processing centers for the products to get ready to leave cell
lysosomes/suicide sac
⭕️️animals (some ♻️)
- unicellular- digestion of food
- multicellular- breaks down organelles, defends against disease
mitochondria
♻️⭕️
- provides and releases energy to power cellular activities
- have own DNA and ribosomes
chloroplasts/plastids
♻️
-site of photosynthesis
cell wall
♻️
-gives cell it’s shape and provides protection
vacuoles
♻️⭕️
-storage centers-guild filled organelles enclosed by a membrane
cilia/flagella
⭕️
-involved in cellular movement
centrioles
⭕️
-helps in cell division
cytoskeleton
- network of fibers that organizes structures and activities within cell
1. microtubules
2. microfilaments
3. intermediate filaments
microtubules
- helps cellular shape, movement
- helps organelle movement
- helps chromosome movement during cell division
microfilaments
- maintains cell shape
- involved in changes in cell shape
- muscle contraction
- cytoplasmic streaming
- division in animal cells
intermediate filaments
- helps maintain cell shape
- anchor nucleus
