Cell theory (3)
1.basic unit of life
2. Functions of lifec
3. Make nucleus
Hierarchical organization of life
Cell -basic unit
Tissue - works tg to form function
Organ - structure made of tissue
Organ system - collection of organisms
Organism - living thing with live functions
Cellular functions
Review other quiz
Cell division
Interphase
Prophasr
Metaphase
Cytokinesis
Telophse
Anaphase
G1 phase
-Gap 1 cell growth
-The cell produces new proteins and organelles
S phase
-Gap 2 cell growth
- cell duplicates its dna and key proteins are produced
- dna is less compressed now in long stands of chromatin
G2 phase
-Gap 2 cell growth
-Prep for mitosis: all 3 stages the cell grows by production
Cytokinesis
Creates 2 daughter cells
The importance of different organelles in mitosis and what would happen if they weren’t working
-centrioles
-Nucleus
-cell membrane
-Spindle fibres
-cytoplasm
Identify types of tissues in plant cell
Ground
Vascular
Epidermis
Meritisimatic
Identify types of tissues in animal cells
Epithieal
Muscle
Nervous
Connective
Stem cells and why they are importsnd in research
-Stem cells help with growing
-How they become specialized and come out, scientist, understand how to choose form during development
-regeneration replaced or regrown
-personalized medicine
-studying genetic disorders
Properties of a cancer cell vs a normal cell
Cancer:
small cytoplasm
Multiple nuclei
Coarse chromstin multiple large nuclei
Regular:
Large cytoplasm
Single nucleus
Single Nucleos
Fine chromatin
Cell specialization, special tissues, and their functions, which sell specialize
Cell specialization is the process which generic and specialized cells become specialized perform specific functions in the body
Muscle cell
Cardiac, skeletal, smooth
Allows movement
Nerve cells
Nervous tissue
Electrical signals + communication
Red blood cells
Blood tissue
Carry oxygen
White blood cells
Blood tissue
Immune system defend infections
Epethial cells
Tissues organs and skin
To protect
Sperm and egg cells
Reproductive tissue
Carry genetic information
Get cells
Type of connective tissue
Story energy
Bone cells
Bone tissue
Maintaining repair bone structure
Genetic therapy and cloning for plant
Plant:
Vegetative- taking a cutting from a plant to produce
Grafting- root attracted to other roots
Genetic therapy and cloning animal
Reproductive- nucleus into egg that has to nuclues
Gene cloning- gene into bacteria +reproduce multiple times
Therapeutic cloning- embryonic stem cells from a developing embryo
