LIFEPAC Study Set Science 1004
Caulpera
Isn't divided into cells but has many nuclei
Cell theory
The cell is the basic unit of life
what the plasma membrane is made of
a double layer of phospholipids with protein throughout
tissue
a group of cells working together to prefrom a certain task
system
a group of organs working together for a common purpose
meiosis
division of the nucleus in reproductive cells
glycolysis
ends with the production of pyruvic acid
mitochondria
energy producing organelles
ATP
energy producing, or energy storing molecule
digestion
food vacuoles and lysosome
animal cells shrivel up
in hypertonic solution
vacuole
large storage structures
What the bible teaches
our bodies were created, then had life breathed into them
erythrocytes
red blood cells that contain hemoglobin
cytokinesis
seperation of the cytoplasm
nucleolus
small structure within cell
secretions
substances produced by golgi bodies which are released outside the cell
organism
the Amoeba
function of a neuron
transmit nerve impulses within the nervous system
axon function
transmits impulses away from the cell body
endoplasmic reticulum
transportation routes in cell
osmosis
water moves freely through the membrane to a higher to a lower concentration
isotonic
water solution that has the same salt concentration as the cell
leukocytes
white blood cells that do not contain hemoglobin
acellular organism
An organism not divided into cells.
Two precautions to avoid damaging the microscope
Carry it with both hands and look at the side of the microscope when changing objectives
1st step of the use of a microscope
Hold the arm in one hand and the base in the other
Slime mold
One example of the cell theory because pairs of cells come together to form the whole organism
semipermeable
Only certain substances can pass through
Plasma membrane
Outer covering that allows some materials into the cell and excludes other materials
Organismal theory
The organism is the basic unit of life
One difference between human cheek cells and onion cells
absence of cell wall in human cells
pinocytosis
Cell drinking
phagocytosis
Cell eating
nucleus
Control center of the cell
cytoplasm
all cellular material outside the nucleus
epidermis
an outer covering of cells
dendrites function
transmits impulses from other neurons to the cell body
active transport
cells that try to work against diffusion by increasing or lowering concentration
hypotonic
cells will become more clump
nucleoli
construct ribosomes
Homeostasis
maintenance of constant conditions by the body
ribosome
makes proteins
passive diffusion
molecules that move in and out freely from high to low concentration
facilitated diffusion
moves from region from high to low concentration if helped across the membrane
cell wall
outer covering around plant cell made of fibrous material
cellular respiration
passive diffusion
ingestion
phagocytosis
Golgi bodies
produce and package secretions
centrioles
spindle production for cell division
plastids
store foods and pigments
