2.1 Flashcards
(14 cards)
1
Q
Organelles
A
- Internalized structures
- Carries out specilized functions
- Reactions occurs in the cytosol
2
Q
Plasma Membrane
A
- Made of phospholipid bilayer
- Substances move in and out of cell
- Plant cells have cell walls: protection, and structural support
3
Q
The Nuclueas
A
- Controls cell activity
- Contains almost all DNA
- surrounded by nuclear envelop
- contains nucleuoplasim
- Nucleuolus inside makes ribosomes
4
Q
Ribosomes
A
- builds protains
- attaches amino acid chains
5
Q
The endobrane system
A
- Group of interacting organelles that work with nucleus and cytosol
6
Q
Rough Endoplasmic Reteculum
A
- Covered in ribosomes, stores proteins for transport
Secretes a lot of protains = more ER
7
Q
Smooth Endoplasmic Reticulum
A
- Makes most of cell membrane’s lipids
8
Q
Vesicals
A
- Sac-like organelles
- Many different functions with varying cells
- Most plants and animals use to dispose of waste
- Plants have large vacuoles:
- Maintain fluid pressure
- takes up 50%-90% of space
9
Q
Lysosomes
A
- Contains powerful digestive enzymes
10
Q
Golgi Bodies
A
- Vesicals fuse with golgi bodies to dispose waste
- Contains enzymes
- Finished products are stored and packaged to be transported to lysosomes
11
Q
Mitochondria
A
- Makes ATN via cellular respiration
- Cells with high energy demands, such as muscle cells, have more mitochondria.
- 2 membranes
- Cistea are the highly folded ones for more SA
- evolved through endosymbiosis
12
Q
Plastids
A
Used or photosyn. or storage
- Chroloplasts
- Used by plants for photosynthesis
- Evolved through endosymbiosis
- Chromoplasts
- Makes pigment other than chroloplasts. Ex. red or orange carotenoids
- Amyoplastids
- Unpigmented plasmids that stores starch
13
Q
The Dynamic Cytoskeleton
IMAGE
A
Microtubule
- Hollow cylinder made of tublin protein
Microfliement
- Fibre made of actin protein
- Used for muscle movement
- Helps strengthen cells
Intermediate Fliement
- Most stable part of cytoskeleton
- Fibrious proteins strengthen and maintain cell structure
- Toughest part of skeleton fliement
14
Q
Ex of cillia, fegella, pseudopods
A
- paramecium
- human sperm
- amoeba
