Cell Theory
First Cell Theory: All living things are made of...
One or more cells
Do prokaryotes contain a nucleus?
NO! PRO-NO
These make proteins and look like tiny dots.
Ribosomes
Our cell membrane is made of...
Phospholipids
Does osmosis require energy?
No. It happens naturally
Second Cell Theory: The size of an organism is determined by the SIZE of cells or the NUMBER of cells?
Number
True or false? All Eukaryotes contain a nucleus, even protists.
True! EU-DO
Explain the two different types of Endoplasmic Reticulum.
Rough and smooth
Rough= contains ribosomes
Smooth= Does not contain ribosomes
What layer of the cell membrane is hydrophobic?
The inner layer (the tails)
Water will always flow to the side with [blank] solute concentration.
Greater
Third Cell Theory: All cells come from...
Pre-existing cells
DNA
Endocytosis is the process of bringing things into cells and Exocytosis is the process of moving things out of cells. What organelle makes this TRANSPORT possible?
Vesicles/Vacuoles (Delivery Trucks)
What are the two main types of transport? Do they both require energy?
Passive: Does not require energy (Diffusion)
Active: Requires energy
What are the 3 types solutions a cell may find itself in?
Hypotonic (Hippo)
Hypertonic
Isotonic (I so happy)
The only part of the cell that grows is...
Cytoplasm
Bacteria
This organelle is responsible for cellular respiration.
Mitochondria (Powerhouse of the cell)
What are the three types of passive transport?
1. Simple Diffusion
2. Passive Diffusion
3. Osmosis
In a Hypotonic solution, what will happen to the cell?
It will swell
When a cell grows, does it become more or less efficient?
Less efficient
Name the four Eukaryotic organisms.
Protists, Fungi, Plants, Animals
This organelle plays a huge role in digestion.
Lysosomes (cleaner lysol)
What are the two types of Active Transport?
1. Protein Pumps
2. Bulk Transport
In a Hypertonic solution, the cell will
Shrink/shrivel
