eukaryotic organisms 1.2 Flashcards
plants are … and have …
multicellular (made up of many specialised cells)
chloroplasts (for photosynthesis) and cellulose cell wall
plants make what on their own?
make their own complex biological molecules by photosynthesis
what do plants store?
store carbohydrates as starch or sucrose
animals are … and have …
multicellular (made up of many specialised cells)
nervous system for coordination and movement
how do animals store carbohydrates?
as glycogen
what do animals do to obtain nutrients?
eat other living things
what do animals not have in contrast to plants?
do not have chloroplasts or cell wall
examples of plants:
flowering plants, such as cereal (maize)
herbaceous legume (peas or beans)
fungi are …and have …
many multicellular, some unicellular (yeast)
consist of threads of cells called hyphae
the whole structure is called a mycelium
some fungi have a reproductive structure
like mushrooms or toadstool
what do fungi feed?
feed by saprotrophic nutrition
- extracellular secretion of digestive enzymes onto food material and absorption of the nutrients into their cells
fungi’s cells have :
no chloroplasts
chitin cell wall
many nuclei per cell
how do fungi store carbohydrates?
glycogen
examples of fungi :
mucor (has typical fungal hyphal structure, and yeast which is single-celled)
protoctista is … and has …
single-celled
very small
chloroplasts (for photosynthesis)
cell wall
flagella for movement
how do protoctistas survive?
some photosynthesise
others feed on living organisms or organic remains
