The cell theory states...
|
All living things are made up of cell/s
Basic unit and structure and function of living things Cells come from other cells |
|
|
Magnification
|
the ability to make things look larger than their normal appearance
|
|
|
Resolution
|
ability to distinguish individual parts of an object
|
|
|
Describe the differences between animal and plant cells
|
animal cells don't have cells walls and chloroplasts
|
|
|
Organelle
|
a tiny cell structure that carries out a specific function within the cell
|
|
|
Cell membrane
|
a structure in the cell which controls which substances can leave or enter the cell
|
|
|
Cell wall
|
a rigid layer of nonliving material that surrounds the cells of plants and some other organisms
|
|
|
Nucleus
|
the dense area in a eukaryotic cell that contains nucleic acids, the chemical instructions that direct the cells activities
|
|
|
Chromatin
|
materials in a cell that contain DNA and carries genetic information floating in
|
|
|
Cytoplasm
|
The region between the cell membrane and the nucleus (in eukaryotes); in organisms without a nucleus (prokaryote), the region located inside of the cell membrane
|
|
|
Mitochondrion
|
rod-shaed structures that produce most of the energy needed to carry out the cels functions
|
|
|
Endoplasmic Reticulum
|
a cell structure that forms a maze of passageways in which proteins and other materials are carried from on part of the cell to another
|
|
|
Ribosomes
|
tiny structures located in the cytoplasm of a cell where proteins are made
|
|
|
Chloroplast
|
captures energy from sunlight and uses it to produce food (plant cells)
|
|
|
Golgi Body
|
a structure in a cell that recieves proteins and other newly formed materials from the ER, packages them and distributes them to other parts of the cell
|
|
|
Vacuole
|
a large sac-like storage area in a cell
|
|
|
Lysosomes
|
4 small round cell structures that contain chemicals that break down larger food particles into smaller ones
|
|
|
Main groups of organic compounds in living things
|
carbohydrates
lipids proteins nucleic acids |
|
|
Examples of each type of organic compound
|
patatoes
fats meat DNA |
|
|
Describe the 3 methods by which substances can move into and out of cells
|
diffusion- HI-LO, passive transport (doesn't require energy) CO2 O2
osmosis- HI-LO passive transport (no energy) H2O active transport- LO-HI active transport (needs energy) A.engulfing B.transport proteins |
|
|
selectively permeable
|
property of cell membrane that allows some substances to pass through while others cannot
|
|
|
passive transport
|
movement of materials through cell without using energy
|
