Science Unit 2 Flashcards
all living things
organisms
Substances that provide energy and materials organisms need to grow
nutrients
anything that causes a response in an organism
Stimulus
reacting to something with your entire body
Response
carries out a specific task
functions
used for a specific function
structures
a group of tissues that work together to create a specific function
organ
a group of organs that work together
organ system
the area that you can see through a microscope
field of view
supports the plant and stores food
storage tissue
tube-like cells with a hollow center
transport tissue
waterproof layer that helps protect the plant
protective tissue
uses sunlight to produce sugar
photosynthetic tissue
supports and connects different parts of the body
connective tissue
covers your body and the outside of organisms
Epithelial
makes up the brain, spinal cord, and nerves
nervous tissue
allows you to move
muscle tissue
various kinds of cells
specialized cells
the diffusion of water particles through a selectively permeable membrane
osmosis
describes a membrane with a very small opening
selectively permeable
microscopic organisms
micro-organisms
made up of 1 cell
Unicellular
made up of 2 or more cells
multicellular
a group of organisms
mycoplasma
the “solar panels” of the cell
chloroplasts
the frame of the cell
cell wall
contains nutrients required by the cell to maintain its life purposes
cytoplasm
where nutrients and water are stored
vacuoles
hair-like structures that parameciums live in
cilia
the movement through a cell membrane
diffusion
lets materials in and waste out
cell membrane
the “powerhouse” of the cell where chemical reactions occur
mitochondria
the “command center” that directs all cellular activities
nucleous
