VOCABULARY 1
What is Cellular Respiration?
the process by which cells use oxygen to produce energy from food.
What is Osmosis?
a cell with a nucleus
Eukaryotic Cell
Chloroplast
Turns plants green and helps with photosynthesis
Nucleus
A part of the cell containing DNA and RNA and responsible for growth and reproduction
What is Photosynthesis?
process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food
What is Glucose? or "C6H12O6"
the sugar used in photosynthesis and cellular respiration
a cell WITHOUT a nucleus
Prokaryotic Cell
Cell Wall
A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
Ribosome
small particle in the cell on which proteins are assembled; made of RNA and protein
What is Active Transport?
cell processes that DO use energy; substances move from a low to high concentration with energy.
What is Passive Transport?
Diffusion of molecules across the cell membrane WITHOUT the use of energy
what are the three "ingredients" needed for Photosynthesis?
sunlight, carbon dioxide, and water (H20)
Golgi bodies or apparatus
organelles that package cellular materials and transport them within the cell or out of the cell
Mitochrondria
Powerhouse of the cell, organelle that is the site of ATP (energy) production
What is a Transport Protein?
Protein embedded in the cell membrane responsible for "picking up" molecules from the outside or inside of the cell and carrying them across the cell membrane
What does Semi-permeable mean?
A property of the cell membrane that allows only certain substances to enter or leave the cell, helping maintain homeostasis.
the basic structural and functional unit of all living things?
a cell
Lysosome
cell organelle filled with enzymes needed to break down certain materials in the cell
Cell Wall
A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
What is Exocytosis?
cell releases a particle by enclosing it in a vesicle and moving it outside cell
What is Endocytosis
process by which a cell membrane surrounds particle, encloses particle in a vesicle to bring the particle INTO the cell
what is the correct organization of a cell? (Think of the squirrel)
cell>tissue>organ>organ system>organism
Endoplasmic Reticulum (ER)
interconnected network of thin, folded membranes that produce, process, and distribute proteins
Nucleolus
Found inside the nucleus and produces ribosomes
