1.2 Cells Flashcards
1
Q
NUCLEUS
A
- Contains hereditary material (DNA and RNA)
- Encodes Info for protein synthesis
- Houses 3 types of RNA, Move to cytoplasm for protein synthesis
- mRNA messenger RNA
- rRNA Ribosomal RNA
- tRNA Transfer RNA
2
Q
CHROMATIN
A
-COMPLETE STRUCTURE OF DNA
3
Q
NUCLEOLUS
A
-rRNA IS PROCESSED INTO RIBOSOMES
4
Q
NUCLEAR ENVELOPE
A
- SURROUNDS NUCLEUS
- 2 NUCLEAR MEMBRANES
- MATERIALS MOVES THROUGH PORES
5
Q
CYTOPLASM
A
- SOLUTION CONTAINING WATER ELECTROLYTES, PROTEINS, FATS, AND GLYCOGEN ORGANELLES
- ORGANELLES FOUND INSIDE : RIBOSOMES, ER, GOLGI COMPLEX, MITOCHONDRIA, LYSOSOMES.
6
Q
RIBOSOMES
A
SITE OF PROTEIN SYNTHESIS
7
Q
ENDOPLASMIC RETICULUM
A
- TRANSPORT SYSTEM FOR SUBSTANCE
- ROUGH ER: CARRIES RIBOSOMES, SYNTHESIZE LYSOSOMAL ENZYMES
- SMOOTH ER:DOES NOT CARRY RIBOSOMES. LIPIDS, LIPOPROTEINS AND STEROID HORMONES ARE MADE.
8
Q
GOLGI APPERATUS
A
-MODIFIES SUBSTANCE PRODUCED IN ER AND PACKAGES THEM INTO VESICLES
9
Q
LYSOSOMES
A
- DIGESTIVE CAPACITY OF CELL
- HUGE ROLE IN METABOLISM
- BREAKS DOWN MATERIAL THROUGH HETEROPHAGY OR AUTOPHAGY
10
Q
MITOCHONDRIA
A
- POWER HOUSE OF CELL
- TRANSFORMS ORGANIC COMPOUNDS INTO ENERGY
- CELLS STORE THE ENERGY AS ATP
11

CYTOSKELETON
A
NETWORK OF MICRO-TUBES AND MICROFILAMENTS
12
Q
MICOTUBULES
A
MADE OF PROTEIN SUBUNITS CALLED TUBULINS
13
Q
CENTROLS
A
HELPS TO SEPARATE AND MOVE CHROMOSOMES
14

MICROFILAMENT
A
THREAD LIKE STRUCTURES THAT PROVIDES SUPPORT FOR CELLS.
3 TYPES- 1). THIN MICROFILAMENTS 2). INTERMEDIATE FILAMENTS 3).THICK MYOSIN FILAMENTS
15
