States of Matter
State the 3 physical states of matter.
Solid, Liquid, Gas
What is evaporation?
The process of turning from liquid into vapor.
What is a cell?
The smallest living units that make up a living thing.
Name the 3 MOVEMENTS in and out of the cell.
Diffusion, Osmosis, Active Transport
Describe the particles in gas. (arrangement, distance, movement,..)
The particles are arranged irregularly, the distance between them is very far apart/spreads, movement is random.
Some living things are unicellular and....
multicellular
The name for energy currency of cells.
ATP
Explain melting point.
A temperature at which a substance turns into liquid.
Animal cell consists of..
cell membrane, cytoplasm, mitochondria, nucleus, ribosomes, small vacuole.
Name the process of water molecules entering the root hair cell.
Osmosis
Explain the process of freezing.
The process where a liquid transforms into a solid due to a decrease in temperature
The function of a vacuole in a plant cell
Water storage, nutrients, and waste management.
Describe the difference between diffusion and active transport.
Diffusion is the particle movement from an area with high concentration to a lower area of concentration, while active transport particles goes against a concentration gradient, going from low to high area of concentration.
Explain Latent heat.
the energy absorbed or released by a substance during a phase change (like melting or boiling) at a constant temperature.
What does Bacteria, plant, and animal cells have in common?
Ribosomes, cell membrane, cytoplasm
What is an isotonic solution?
When the concentration of solute is equally the same between the inside and outside of the cell.
