cells chapter 5 Flashcards
0
Q
plasma/cell membrane
A
♻️⭕️both plants and animals
- thin, flexible Barrie around cell
- controls movement in and out of cell
1
Q
cell theory
A
- 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
2
Q
cytoplasm
A
- jelly like substance that fills the cell
- holds the organelles
- location of chemical reactions
3
Q
cell types
A
prokaryotic
eukaryotic
4
Q
prokaryotic
A
- no nucleus or ribosomes, scattered DNA
- EX bacteria
5
Q
eukaryotic
A
- nucleus with DNA and membrane bound organelles
- EX animals plants protists fungi
6
Q
nucleus
A
♻️⭕️both
- “control center”
- membrane bound
- contains DNA
- has nucleolus
7
Q
nucleolus
A
-produces ribosomes
8
Q
endoplasmic reticulum
A
♻️⭕️both
- system of fluid canals enclosed my membranes
- transports materials throughout cell
9
Q
ribosomes
A
♻️⭕️both
-make proteins
10
Q
Golgi bodies/Golgi apparatus
A
♻️⭕️both
-processing centers for the products to get ready to leave cell
11
Q
lysosomes/suicide sac
A
⭕️️animals (some ♻️)
- unicellular- digestion of food
- multicellular- breaks down organelles, defends against disease
12
Q
mitochondria
A
♻️⭕️
- provides and releases energy to power cellular activities
- have own DNA and ribosomes
13
Q
chloroplasts/plastids
A
♻️
-site of photosynthesis
14
Q
cell wall
A
♻️
-gives cell it’s shape and provides protection
