Term
cells
Definition
all living things are made of these. They are too small to be seen or examined except through a microscope.
Term
plant cells
Definition
have a rectangular shape. Its parts include chloroplasts that use sun light to make its food and a cell wall to give it structure
Term
animal cells
Definition
have an irregular shape with the same basic parts of the plant cell like the cell membrane, nucleus, cytoplasm and vacuoles with the exception of a cell wall and chloroplasts
Term
nucleus
Definition
found in both cells; the cell’s “command center”, or brain
Term
cell wall
Definition
only in plants; the thick, rigid outer covering of a plant cell taht gives the plant structure and support
Term
cell membrane
Definition
found in both cells; the lining that controls what goes in and out of each cell; it surrounds and protects each cell (acts like a fence)
Term
vacuole
Definition
found in both cells; this part stores water and wastes
Term
cytoplasm
Definition
found in both cells; the jelly-like substance that fills the inside of the cell; all other parts float around in it.
Term
chloroplasts
Definition
only in plant cells; they are small and round, and use sunlight to produce plant sugars (*think chlorophyll)
Term
organism
Definition
a living thing
Term
photosynthesis
Definition
the process of using the sunlight to make food for plants
Term
vertebrate animals
Definition
have a backbone or spine like a fish, frog, or bird
Term
invertebrate animals
Definition
don’t have a backbone or spine like a jellyfish, snail, or bee
Term
vascular plants
Definition
grow TALL due to special tubes in their roots and stems to carry water and nutrients throughout the plant
Term
non-vascular plants
Definition
do not have special tubes to carry water so they must absorb it from where they are located. They are short and low to the ground like mosses and liverworts.
Term
microscope
Definition
tool used to magnify microscopic objects
