contain simple cells
are unicellular
alway have a flagellum
are a product of endosymbiosis

True or False. Prokaryotes contain cytoplasm.
True
False
An organelle involved in breaking down lipids, proteins, carbohydrates, damage organelles, and bacteria are ___
Golgi Appaparatus
Vesicles
Vacule
Lysosomes
Both mitochondria and chloroplasts ____
contain their own unique ribosomes that are different than the cells
contain their own unique DNA that are different than the cells
are specialized organelles that capture and release energy
are found in both in plants and animals
The cell semipermeable membrane governs what comes in and out of the cell through
Diffusion
Osmosis
Facilitated Diffusion
Protein Pumps
The Fluid Mosaic Model __
describes the process of making proteins through the fluid movement of ribosomes to the golgi apparatus
describes the movement of RNA through the nuclear pore into the cytoplasm
describes the cell's boundary composed of the cell wall and the cytoskeleton
describes the cell membrane as made of many different parts that are not fixed in one place.
Cholesterol
Is bad
provides stiffness and structure to the cell's semipermeable membrane
Is good
helps with facilitated diffusion
In diffusion
water moves from a high concentration to a low concentration
water moves from a low concentration to a high concentration
molecules move from a high concentration to a low concentration
molecules move from a low concentration to a high concentration
Water, oxygen and carbon dioxide move across the permeable cell membrane by ____
diffusion
facilitated diffusion
endocytosis
exocytosis
Osmosis is ____
a special kind of diffusion
the movement of water across a permeable cell membrane
a passive transport mechanism
an active transport mechanism
A hypertonic solution is one where
the concentration of a solution outside the cell is higher than the concentration than inside the cell
the concentration of a solution outside the cell is lower than the concentration than inside the cell
the concentration of a solution outside the cell is equal to the concentration than inside the cell
Timmy places a freshwater amoeba on a wet mount slide with freshwater. Timmy examines the amoeba using a compound microscope using high power. What happens to the amoeba body?
Hypertonic setting: the amoeba shrivels up as water in the amoeba moves across it's semi-permeable membrane into the jar of water.
Hypotonic setting: the amoeba swells up as water in the jar moves across the amoeba's semi-permeable membrane into the amoeba's body.
Isotonic setting: nothing happens as the concentration of the freshwater in the jar is equal to the concentration of freshwater in the amoeba's body
The cell membrane is a flexible covering that...
creates structure and support for plant cells
protects the cell from the environment outside of the cell
directs the cells activities
How is a cell membrane like a mesh screen?
it is metal and has holes in it
it allows big things to come through but keeps small things out
it allows small things to come through but keeps big things out
