B1- Cell Structure Flashcards
What is a cell
The unit of a living organism
Eukaryotic cell
Animal,plant and fungus cells. Their DNA is not a confined to a nucleus
Prokaryotic cell
Bacterium cell. Their DNA is not a confined to a nucleus
Mitochondria
The site of respiration
What does the Chloroplasts do in the cell
The site of photosynthesis
Ribosomes
Is the site of protein synthesis
Nucleus
Controls the activities of the cell
Partially permeable membrane
A membrane that only allows certain substances to go through
5 parts of an animal cell
Cell membrane
Ribosome
Nucleus
Cytoplasm
Mitochondria
The 8 parts of a plant cell
Cell wall
Cell membrane
Ribosome
Nucleus
Vacuole
Cytoplasm
Mitochondria
Chloroplast
Diffusion
The spreading of particles from area of high to low concentration
Osmosis
The diffusion of water through a partially permeable membrane from an area of high to low concentration of water
Active transport
Is the movement of substances from a dilute solution to a more concentrated solution
3 factors affecting the rate of diffusion
Higher concentration gradient
High temperature
Large surface area of the membrane
Magnification equation
Magnification= size of image / size of real object
