Plant cells have this rigid structure outside the cell membrane.
Cell Wall
The cell membrane is mainly made of two layers of these molecules.
Phospholipids
This type of transport does not require ATP.
What is passive transport?
This property means water has slightly positive and slightly negative regions.
Polarity
According to cell theory, all living things are made of one or more of these.
This organelle carries out photosynthesis in plant cells.
The phospholipid heads are attracted to water, which is described by this word.
What is hydrophilic?
This process is the diffusion of water across a selectively permeable membrane.
Osmosis
Water molecules sticking to other water molecules is called this.
Cohesion
This organelle contains DNA and controls many cell activities.
Nucleus
Plant cells usually have one large version of this storage organelle.
Central Vacuole
The phospholipid tails avoid water, which is described by this word.
What is hydrophobic?
This transport moves particles from high to low concentration through a transport protein without ATP.
Facilitated Diffusion
These are the building blocks of proteins.
Amino Acids
This organelle builds proteins.
ribosomes
Name two structures found in plant cells but not animal cells.
Cell Wall
Chloroplast
These membrane proteins help specific substances cross the membrane.
What are transport proteins?
In this type of solution, water moves out of an animal cell and the cell shrivels.
Hypertonic
This biomolecule provides quick energy and short-term energy storage.
Carbohydrates
This organelle modifies, sorts, packages, and ships proteins and lipids.
Golgi Apparatus
Name three structures that both plant and animal cells have.
any three of: cell membrane, cytoplasm, nucleus, ribosomes, ER, Golgi apparatus, mitochondria?
This term means the membrane allows some substances to cross more easily than others.
What is selectively permeable?
A potato gains mass after soaking in a solution. What does that tell you about the direction water moved?
Into Potato Cells
When organisms build new biological molecules, atoms are not created or destroyed. Instead, they are ________.
Rearranged
This organelle processes and transports proteins and has ribosomes attached to it.
Rough ER
