Blastula: A hollow ball of cells.
Many organisms form this when they
grow in size to about 256 cells. It is an
early stage in
embryo
development.
Mitochondria: An organelle in
many types of cells. It is the energy
factory of cells. Mitochondria were
probably originally
bacteria that became
symbiotic with other
cells. They have their
own distinct DNA!
Chloroplasts:
An organelle in many plant,
bacteria and protist cells. Chloroplasts are
green and contain chlorophyll. This is where
photosynthesis happens. Chloroplasts were
once independent
bacteria cells, probably
cyanobacteria (the
same bacteria that
gave us an oxygen
atmosphere!).
Nucleus:
Not found in Archea or
Bacteria. The nucleus is found in
Eukaryote cells and contains the DNA in a
cell. It has a
separate
membrane that
protects the
nucleus.
Bilateral: Has a left and right side.
Organisms that have a left and right side are
bilateral. Some bilateral organisms start off
with a left and right side
and then develop into a
different shape or
symmetry (starfish and
flounder are examples).
Collagen: A protein that
is the glue that keeps the
cells of animals together.
Cellulose: A starch like
chemical that is the glue that
keeps the cells of plants
together.
Chitin: A starch like chemical
that is the glue that keeps the
cells of fungi together. Chitin is
also the chemical that makes the
exoskeletons of insects and
related organisms.
