Question | Answer |
smallest structure that carries out activities necessary for life | cell |
structure that performs a specific function within a cell | organelle |
all cells share these 3 features | cell membrane, nucleus, cytoplasm |
the outer covering of the cell | cell membrane |
In addition to the cell membrane plants have this outer covering | cell wall |
controls activities of a cell and carries genetic information | nucleus |
gel-like material that surrounds all parts of the cell within the cell membrane | cytoplasm |
Special organelle found in plants that combines energy from sunlight with water and CO2 to create glucose | chloroplast |
Process of combining energy from sunlight with water and CO2 to create glucose | photosynthesis |
the spread of particles evenly through a liquid or gas | diffusion |
the simplest kind of diffusion in which particles move from an area of high concentration to an area of low concentration | passive transport |
diffusion through a membrane in which certain particles are filtered out | osmosis |
movement of particles from an area of low concentration to an area of high concentration (requires energy) | active transport |
green pigment found in cloropolasts that allow them to capture energy from sunlight | chlorophyll |
this simple sugar is created during photosynthesis | glucose |
organelle in which respiration takes place | mitochondria |
this process is the opposite of photosynthesis | respiration |
the process which allows organisms to grow | cell division |
as cells divide they differentiate and ... | specialize |
