What is a prokaryote?
Bacteria with no nucleus, no membrane bound organelles. Have a cell wall, cell membrane, ribosomes,chromosomes and reproduce Asexually
100
what is active transport?
moving molecules AGAINST OR UP the concentration gradient (molecules move from an area of low concentration to an area of high concentration) uses energy
100
What is Isotonic Solution?
A solution that is balanced therefor equal particles and equal water, it is homeostasis
100
What is hypertonic solution?
like when you have a headache not enough water in cell. water is leaving the cell.
100
What are phospholipids
Cell membrane are composed of two layers of this
200
What is a eukaryote?
Animal, plant, fungus, protists. They have a nucleus. Has all normal organelles reproduce sexually or asexually
200
What is passive transport?
The movement of molecules from an area of greater concentration to an area of lesser concentration. This does not take energy to do (pefume analogy)
200
What is hypertonic solution?
A solution with more particles in the solution, outside therefor the solution with less concentration of water.

200
What is hypotonic solution?
Water going into cell. cell blows up like a balloon
200
What is cholesterol?
Something that strengthens the cell membrane
300
What are Autotrophs?
Make food by photosynthesis, chloroplast, green. Plants, some bacteria, some protists
300
What is diffusion?
The movement of molecules from an area of HIGh concentration to an area of low concentration until the molecules are equally balanced (in the container)
300
What is hypotonic solution?
A solution with less particles in the solution (inside) therefor solution has a greater concentration of water.

300
What is endocytosis?
Bring materials into the cell. Cell membrane surrounds and brings in nutrients
300
What are proteins?
Something that helps materials across the membrane.
400
What is heterotroph?
Goes and gets food, hunt/decompose. Does not have chloroplast. Animals and fungus
400
What is osmosis?
Diffusion of water across a membrane the movement of WATER molecules from an area of greater concentration to an area of lesser concentration THROUGH a membrane
400
What is mitochondria?
Produce energy for the cell (atp)
Has its own dna. Where cellular respiration happens. Get them from your mom therefor you can track mitochondrial DNA to find matriarchal heritage.
400
What is exocytosis?
pushes waste out of the cell.
The cell membrane surrounds and pushes out waste.
400
What are carbohydrates?
something that act as identification tags
500
What are choroplasts?
Have some o their own dna. Found in autotrophs. Always green because they absorb red and green wavelengths and reflect green. Chlorophyll in the pigment that reacts to red and blue light in photosynthesis.
500
What is facilitated diffusion?
Moves molecules down the concentration gradient (from high to low concentration through a protein)
it assists molecules across a membrane
500
What is isotonic solution?
water going in and out of cell
500
What is Phagocytosis?
a form of endocytosis that is specifically bringing in large particles for digesting. It literally means "cell eating" Immune cells called macrophages do phagocytosis to isolate, digest and destroy invading bacteria and viruses.
500
What is the fluid mosaic model.
A model that describes the arrangement of molecules that make up a cell membrane.
