- eukaryotic cells
- large and complex-distinguished by the presence of a true nucleus. the plasma membrane controls the cell's interaction with its enviroment. the cytoplasm of a eukaryotic cellcontains complex structures called organelles. membranes form the boundaries of many of ht eorganelles, compartmentalizing the interior of the cell and thereby enabling the cell to carry out a variety of metabolic activites simultaneously.
- type of m'scope used to study the finest details of surface texture of a human hair?
- scanning electron microscope
- SEM vs. TEM
- sem-scanning[looks 3-E image. used to study architecture of cell] tem-transmission[looks like a drawing. used to study details of cell]
- which of the following organelles does not belong in this list: mitochondria, chloroplast, ribosome, lysosome, peroxisome? why?
- RIBOSOMES- because it is the only organelle in the list that is not bounded by a membrane.
- how mitochondria produces energy....
- CELLULAR RESPIRATION-- chem#1 + chem#2 = glucose +ATP... done in plant and animal cells. formula: C6H12O6+6O2=6CO2+6H2O+ATP. [1glucose=38ATP (cytoplasm=2)(matrix=2)(cristae=34)]
- plant cell
- is a cell that has a cell wall and is geometric in shape.
- type of m'scope used to study the detailed structure of an organelle in the cytoplasmof a human liver cell?
- transmission electron microscope
- type of microscope used to study the changes in shape of a living juman white blood cell
- light microscope
- animal cell
- a cell that does not have a cell wall and has no geometric shape.
- you need ATP because...
- its energy our body can handle. glucose is too much to handle.
- prokaryotic cells
- bacteria and archaea-small, relatively simple cells that do not have a nucleus. a prokaryotic cell is enclosed by a plasma membrane and usually encased in a rigid cell wall. the cell wall may be covered with a sticky capsule. inside the cell, its DNA and other parts are suspended in semi-fluid cytoplasm. prokayotic flagella may propel the organism.
- how cloroplast producers energy...
- PHOTOSYNTHESIS --- solar energy=light/chem energy(food)=glucose.....through "photosynthesis" 6CO2+6H2O --->(light) 6O2+C6H12O6...in granum in daytime and in stroma at nighttime
- cell parts IN ORDER:
- 1-nucleus 2-ribosomes 3-rough/smooth ER membranes 4-Golgi apparatus
