- energy rich organic compound made of elements c, h , o
- carbohydrate
- the smallest unit of an element
- atom
- when 2 or more elements combine chemically
- compound
- what are organelles?
- carry out specific functions witin the cell.
- compounds that dont contain carbon
- organic compounds
- ability to clearly distinguish the individual parts of an object
- resoulution
- smallest unit of most compounds
- molecule
- what is the cell membranes main functions?
- controls what substances come into and out of the cell.
- compounds that dont contain the element carbon
- inorganic compounds
- a light microscope that has more then one lens
-
compound microscope
- rod shaped structures, they are the power houses they produce most energy the cell needs to carry out its functions.
-
mitochondria
- basic unit of structure and function
- cell
- the organelles that are found in cytoplasm function:
- to produce energy, build and transport needed materials and store and recycle wastes.
- makes things appear larger
- magnification
- a large oval structure it is the brain of the cell.
- nucleus
- instrument that makes small objects look larger
- microscope
- region btw the cell mem and the nucleus. clear, fluid like material.
- cytoplasm
- thin strands floating in the nucleus. they contain genetic material the instructions that direct the functions of the cell.
- chromatin
- a rigid layer of nonliving material that surrounds the cells of plantrs and some other organisms.
- cell wall
- a lens with a curved shape
- convex lens
- located inside the cell wall, it forms the outside boundary that seperates the cell from its enviroment.
- cell membrane
- widely accepted explanation of the relationship btw cells and living things.
- cell theory
- what are the three things about cell theory?
-
all living things are composed of cells
cells are the basic unti of structure and function in living things
all cells are produced from other cells - they are attached to the outer surface of the ER they are small grainlike bodies.
- ribosomes
- large green scas floating in the cytoplasm. they capture energy from the sunlight and use it to produce food for the cell.
- chloroplasts
- large water filled sac floating in the cytoplasm. it is the storage area for the cell.
- vacuole.
- small round structures that contain chemicals that break down large food particles into smaller ones.
- lyosomes
- flattened collection of sacs and tubes. "the mailroom" they recieve proteins and other newly formed materials from the ER.
- Golgi Bodies
- the passageways carry portein and other material
- endoplasmic reticulum
- is a substance that cannot be broken down into simpler substances.
- element
