Cell Discovery
Two cell types
What are prokaryotes and eukaryotes?
Has a higher concentration of solutes than the cytoplasm of the cell
Hypertonic solution
Powerhouse of the cell.
What is the mitochondria?
Transport ions and polar molecules through the cell membrane. The pores allow substances to pass through without binding to the protein.
Channel proteins
Programmed cell death.
What is apoptosis?
All plant cells are: (cell type)
What are eukaryotes?
Uses transport proteins to move ions and small molecules across the plasma membrane
Facilitated diffusion
Function of vacoules.
What are stores food, enzymes, waste, and water?
They support cell recognition and triggering immune responses.
Glycolipids
Organelles found in plant cells that capture sunlight and use it for energy.
What are chloroplasts?
Requirements for an Electron Microscope
What are dead, thinly sliced, and dyed with heavy metals?
Molecules continue to move, but the concentration remains the same during diffusion.
Equilibrium
Organelle that eats other dead organelles.
What is a lysosome?
Manages the fluidity of the membrane and stops the phospholipids sitting too closely together.
Cholesterol
Microscope most Casady science classes use.
What is a compound light microscope?
Three key principles/rules
What are:
All living organisms are composed of one or more cells
Cells are the basic unit of structure and organization in living things
Cells only arise from previously existing cells that pass on genetic material
has the same concentration of water and solutes as the cytoplasm of the cell
Isotonic solution
Name 2 organelles that ALL cells have.
What are:
Cell membranes, cytoplasm, ribosomes, or DNA code?
They can bind with certain substances and some act as cell markers for cell-to-cell recognition.
Glycoprotein
Two physical cell structures that help cells move.
What are cilia and flagella?
List two differences between prokaryotic cells and eukaryotic cells.
What is answers may vary?
(e.g. no nucleus, membrane bound organelles)
These pumps are found in the plasma membrane of animal cells
Na⁺/K⁺ Pumps
Differences between smooth ER and rough ER.
What are the smooth ER has lipids attached, and the rough ER has ribosomes attached?
OR
What are the smooth ER produces steroids/hormones, and the rough ER produces protein synthesis?
Define the cell characteristics and help cells identify chemical signals.
Carbohydrate chains
The cell membrane surrounds external objects to bring them inside.
What is endocytosis?
