PRE LAB 1.1 CELL COMPONENTS Flashcards
Unique cell components of bacteria
- prokaryotes
-lack enclosed membrane containing DNA (nucleoid)
-no lysosome
-sphere and spiral shape
-plasmid (ring of ds DNA
Unique cell components of plant cell
-plastid (storage sya and under nya is chloroplast)
-chloroplast
-large central vacoule
-plasmodesmata
-rigid cell wall
-autotroph (self-sufficient)
Unique components of animal cell
->lysosome - digestive enzymes that liquify foreign bodies
->no cell wall
->centrosome (area of the cytoplasm from which centrioles are located; formation of spindle apparatus; cell division)
->centrioles (barrel-shaped, bundles microtubules)
->smaller vacuole
Bacteria and Plant cell similarities
-cell wall
- capsule
- no centrioles
-photosynthetic (some)
Bacteria and animal cell
-heterotrophs (some)
-cilia (locomotion)
flagella
Animal and Plant cell
-eukaryotic
-mitochondria
-nucleus
- membrane bound organelles
Similarities of plant, animal, and bacterial cell
-genetic material (DNA and RNA
- Cytoplasm
-Ribosome
- Cell membrane
[ANIMAL AND PLANT] Nucleolus
site of ribosome synthesis
[ANIMAL AND PLANT] Nucleus
contains genes and gentic material– chromatin
ribosomes
site of protein sysnthesis
[ANIMAL AND PLANT] Vesicles
transport of materials for cell survival and recycling waste materials through exocytosis or endocytosis
[ANIMAL AND PLANT] rough ER
-has ribosomes
-protein form ER will be carried by golgi apparatus
[ANIMAL AND PLANT] Golgi apparatus
- storing and packaging lipids, and proteins from ER (courier system)
-distribute, export, and synthesize protein and lipids
[ANIMAL AND PLANT] Cytoskeleton
helps the cell maintain its shape;
mechanical support
[ANIMAL AND PLANT] Smooth ER
lipid synthesis, drug metabolism
[ANIMAL AND PLANT] Mitochonndria
releases ATP (site of CR, kreb, and oxidative phosphorylation)
[ANIMAL AND PLANT] Vacuole
handles waste products; specialized lysosomes
[ALL] Cytosol
fluid substance in cytoplasm
[ALL] Cell membrane
separate the cell from the outside
lipid bilayer
Vacoule sa plant cell
-store water, nutrients, waste products
[PLANT] Chloroplasts
- convert light energy to chemical energy
[PLANT] Plastids function
double membrane organelle differes in pigments
Types of pigments
-chloroplasts -green
-chromoplasts have different colors
-carotenoids
carotene - yellow to orange
xanthophylls - yellow
lycopene- red
do photosynethetic bacteria have chloroplasts?
-bacterial cells lack chloroplasts but some photoautotrophic bacteria conduct photosynthesis as they contain chlorophyll embedded in their membranes
