PLMAT Flashcards
cells
smallest living organism and basic unit of life on earth
3 parts of cell
membrane, the nucleus, and the cytoplasm
what’s nucleus?
contains of the cell’s DNA, sends messages to tell the cell to grow
membrane
ensure cell remains separate
cytoplasm
interiorof cell that surrounds the nucleus.
Cytoskeleton 💀
forms/ helps cell maintain correct shape.
endoplasmic reticulum (ER) 🤛
synthesizes, folds, and transports proteins.
Golgi apparatus 📦
post office of cell, where items go through packaging
mitochondria 🏠
powerhouses of cells.
help turn food into energy that cell can use
Ribosomes
Ribonucleic acid (RNA)
Read RNA and translate it into proteins by sticking together amino acids
two typesof cell division
mm
@ mitosis
most of cells in the body divide. The “parent” cell splits into two “daughter” cells.
@ meiosis
body produces sperm cells and egg cells.
Cell types? SBBMSEN
stem cells
bone cells
blood cells
muscle cells
sperm cell
egg cell
nerve cell
what is blood cell 🩸🩸💉
red blood cells - carry oxygen around body
white blood cells - part of immune system
platelets - help blood clot to prevent blood loss
Isaac Newton
The Father of Modern Physics
Heat and Thermodynamics
Heat- form of energy that produces hotness.
Thermodynamics- deals with the energy relationships involving heat
Methods of heat transfer
CCR
Conduction: transfer of heat from hotter body to colder body
Convection: transmission of heat due to movement of medium
Radiation: heat gets transmitted without the action
Types of equilibrium
TMC
Thermal equilibrium: temperature of every part of the system is the same as surroundings
Mechanical equilibrium: no unbalanced force
Chemical equilibrium: chemical composition is same throughout system.
Internal Energy ⚡🔌
sum total of the kinetic energy
kinetic energy.
energy possessed by atoms by virtue of their motion
Work
energy spent to overcome an external force.
electromagnetism 🔌
produced when electrical flows through conductor
DNA?
Deoxyribonucleic acid - carries genetic information
Molecule?
group of atoms together
Isaac Newton 2nd Law
Law of acceleration
f = ma
Ohms Law
current is voltage
NPN BODIES? 🦭
Negative
have excess electrons
Positive
deficiency of electron.
Neutral
the same number of protons and electrons.
Law of inertia
Isaac Newton - Law of motions
a body at rest will remain at rest
a body in motion will move unless force acts on
