Cell theory Flashcards
Name number one of the cell theory!
All organisms are made of one or more cells
Name number two of the cell theory!
The cell is the basic unit of all living things
Name number three of the cell theory!
All cells come from existing cells
What’s in the plant cell that’s not in the animal cell?
Chloroplast
What’s the easiest to see cell
Chicken egg
What are prokaryotes
A single-celled organism that does not have a nucleus or membrane-bound organelles
What does diffusion mean?
The movement of particles
osmosis
The diffusion of water through a semipermeable membrane
Passive Transport
The movement of substance across a cell membrane without the use of energy by the cell
active transport
the movement of substance across the cell membrane that requires the cell to use energy
endocytosis
the precess by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
exocytosis
the process in which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane
photosynthesis
the process by which plants, algae, and sone bacteria use sunlight, carbon dioxide, and water to make food.
cellular respiration
the process by which cells use oxygen to produce energy from food
fermentation
the breakdown of food without the use of oxygen
cell cycle
the life cycle of a cell
chromosome
in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
Homologous chromosomes
chromosomes that have the same sequence of genes and the same structures
mitosis
in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
cytokinesis
the division of the cytoplasm of a cell
