what are the 6 charicterisics of living things |
Living things are made of cells.
Living things obtain and use energy. Living things grow and develop. Living things reproduce. Living things respond to their environment. Living things adapt to their environment. |
|
|
What does the mitochondria do |
its where chemical reactionoccur converting nutients into energy a cell can use (ATP) this proccess is called cellular respiration. |
|
|
what is the nucleus |
it is at the center of a cell directsmovement growth and life functions its where dna is found |
|
|
Ribosomes |
Assemble proteins they can be found floating in the cytoplasm or attatched to the ER |
|
|
Cell membrane |
it lets certain materials in and keeps others out itseperates the interior of the cell from its surroundings |
|
|
Cytoplasm |
this contains all the nutrients neccesary for life and regulates the pressure in the cell. |
|
|
ER
|
its a network of channels that transports materials tyhroughout the cell the er is folded in order to minimize space and to maximize surface area |
|
|
Golgi Body |
it recieves the proteins after the ribosomes and it soryts and packs the proteins into structures called vesicles (miny vacuoles) |
|
|
Centriole |
each animal cell has 2 of these and they help the cells divide |
|
|
lysosomes |
They digest unwanted waste |
|
|
vacuoles |
storage rooms that sore water nutrients and sometimes waste plants have 1 huge one animals have many. |
|
|
cell wall |
frames and supports the cell plant cells only |
|
|
chloroplasts |
they are found in the green parts of the plants and convert the suns energy into food using photosynthisis |
|
|
cell theory |
the cell is the basic unit of life all orginisms are made up of 1 or more cells all cells come from other living cells |
|
|
what organelles are only in plant cells |
cell walls chloroplasts giant vacuole |
|
|
what organelles are only in animal cells |
tiny vacuoles centriole |
|
|
osmosis |
the difution of water across a membrane |
|
|
diffusion |
is the process of molecules spread from areas of high concentration to areas of low concentration. |
|
|
you need to know how a microscope works and the parts of a microscope |
