Cell Structure and Function Flashcards
1
Q
cell theory
A
- organisms made of one or more cells
- vital functions occur within cells
- contain hereditary info
- – transmits info to next gen
2
Q
two types of cells
A
eukaryotes and prokaryotes
3
Q
prokaryotes
A
- single cell
- no nucleus
- peptidoglycan cell walls
- binary fission
- energy=organic/inorganic/or photosynthesis
4
Q
archaea
A
- no peptidoglycan in the cell wall
- extreme environments
5
Q
organelles
A
membrane-bounded compartments that are specialized for specific functions
6
Q
cell wall
A
found in plants, bacteria, fungi
-contain cellulose
7
Q
cytoplasm
A
viscous fluid containing organelles
8
Q
endoplasmic reticulum (ER)
A
network of interconnected membranes comprising tubules
9
Q
golgi apparatus
A
important for processing of proteins for secretion
10
Q
lysosomes
A
“suicide-sacs”
digests excess or worn-out organelles, food, or bacteria
11
Q
vacuoles
A
storage sacs
12
Q
tonoplast
A
surrounds vacuole
-regulates movements of ions around the cell
13
Q
mitochondria
A
generates ATP -involved in: cell signalling cellular differentiation cell death control of the cell cycle cell growth
14
Q
chloroplasts
A
- photosynthesis
- fatty acid synthesis in plants
- involved in a plant’s immune response
15
Q
true-membrane bound nucleus
A
eukaryotic cell
