plant cell vs animal cell differences
Plant cells have a cell wall, animal cells do not. Animal cells have Lysosomes, plant cells do not.
a rigid layer of nonliving materal that surrounds the cell of plants and some other organisms
located just inside the cell wall and controls what substances come into and out of a cell
"powerhouses" of the cell - they convert energy in food molecules to energy the cell can use to carry out its function
passageways that carry protiens and other materials from one part of the cell to another
part of an animal cell. receive material from the endoplasmic reticulum and send them to other parts of the cell.
part of plant cell. capture energy from sunlight and use it to produce food for the cell
part of animal cell. contain chemicals that break down food particles and warn-out cell parts
the movement of DISSOLVED material thorough the cell membrand WITHOUT using cellular energy
process by which cells obtain energy from glucose. during respiration cells break down simple food molecules such as sugar and release the energy they contain.
producers take in carbon dioxide gas during photosynthesis. they use carbon from the carbon dioxide ot make food molecules. when consumers eat producesr they take in the carbon-contaiing food molecules. when consumers break down these food molecules to obtain energy, they rlease carbon dioxide and water as waste products. when producers and consmers die, decomposers break down their remains and return carbon compounts to the soil. some decomposers also release carbon dioxide as a waste product.
producers release oxygwn as a result of photosynthesis. most organisms take in oxygen from the air or water and use it to carry out their life processes,.
the process by whihc a new organism deelops from the joining of two sex cells - a male sperm cell and a female egg cell.
process by which a single organism produces a new organism identical to itself.
a process where genes from one organism are transferred into the DNA of another organism.
the process of selecting a few organisms with desired traits to serve as parents of the next generation
a chart that shows all the possible combination of allels that can result from a genetic cross.
energy-containing nutrients that are composed of carbon, oxygen, and hydrogen. Fats form part of the cell membrane. Fatty tisssue protects and supports your internal organs and insulates your body.
nutrients that contain nitrogen as well as carbon, hydrogen and oxygen. Needed for tissue growth and repair.
energy-rich organic compounds made o f carbon, hydrogen and oxygen. Contain more energy than carbohydrates. Cells store energy in lipids for later use.
the amount of energy needed to raise the temperator of one gram of water by one degree Celcius.
the virus that causes AIDS. The only kind of virus known to attack the human immune system directly and destroy T cells.
