multicellular or single celled Flashcards
what’s osmosis
osmosis is the net movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration
what’s diffusion
diffusion is the net movement of particles from an area of higher concentration to an area of lower concentration
what’s the difference between an animal and plant cell
a plant cell has a vacuole, cell wall and a chloroplast
is bacteria multi cellular or single celled
single celled
is protoctists multi cellular or single celled
single celled
what is active transport
active transport is the movement of particles against a concentration from an area of lower concentration to an area of higher concentration) using energy released during respiration.
is fungi multi cellular or single celled
single celled
examples of fungi
yeast-single celled
mucor- multicellular
examples of protoctists
chlorella
amoeba
examples of bacteria
lactobacillus bulgaricus- rod shaped
pneumococcus- spherical in shaped
definition/description of fungi
they can’t photosynthesise
their cells have cell walls made of chitin
they can store carbohydrates as glycogen
definition/description of protoctists
they are microscopic
some have chloroplasts and are similar to plant cells
other are more like animal cells
definition/description of bacteria
they are microscopic
they dont have a nucleus
they have a circular chromosome of DNA
some can photosynthesise
most bacteria feed off other living or dead organisms
what’s a pathogen
pathogens are organism that cause disease
what’s eukaryotic
Eukaryotic are organisms whose cells contain a nucleus and other membrane-bound organelles.
