Organelles
Storage site of hereditary material.
Nuclues
Passive movement of small molecules from high concentration to low concentration
Diffusion
Is a smaller surface area to volume ratio better for cell diffusion?
No
Found mostly in the leaves of plants, and the site of glucose synthesis.
Chloroplasts.
Active transport requires what?
Energy
What features does a prokaryotic cell not have that a eukaryotic cell does?
Membrane bound organelles
Vesicles are often formed here and sent out of the cell.
Golgi body.
Passive movement of larger molecules down the concentration gradient.
Fascilitated diffusion.
Describe the three points of cell theory.
1. All living things are made up from one or more cells.
2. Cells carry out all life processes of an organism.
3. All cells are derived from other cells.
Uses glucose and oxygen to create ATP, a molecule that is used by the cell for reactions that require energy.
Mitochondria.
Osmosis is the movement of water from where to where?
What is the name of the process by which a prokaryotic cell divides into two daughter cells?
Binary Fission
Site of protein synthesis and located near the nucleus of the cell.
Smooth Endoplasmic Reticulum
Describe the process of exocytosis.
A vesicle is formed by the golgi body and moved through the cell to the cell membrane with the help of the cytoskeleton. Upon reaching the cell membrane the vesicle fuses with the cell membrane, releasing its contents.
What are the 6 factors that define a living being?
The ability to:
Control its internal environment (homeostasis)
Reproduce
Grow and develop
Use energy from its surroundings (eg. aerobic respiration)
Respond to stimuli
Adapt (evolve) to its environment (as a population)
