Types of Cells and Microscope Calibration Flashcards
Simple plants have close contact with…
the environment for gaseous exchange, water and import of nutrients.
Simple plants have no need for…
…different cell types.
Simple plants undergo Very little or no…
…cellular differentiation, cells all the same
Higher plants are usually …
…large and multicellular.
Not all higher plant cells in close contact with …
…environment
Higher plant cells need to be …
…specialised.
Types of potential specialisation within higher plants?
Support
Photosynthesis
Water uptake
Water or nutrient transport
Protection
Gaseous exchange
Cell proliferation
In higher plants, there are many…
…different cell types due to Cellular differentiation (cells not all the same)
Simple animal cells have close contact with…
…the environment for gaseous exchange, water and import of nutrients/capture of prey
Simple animals have no need for…
…different cell types.
In simple animals, there is Very little or no…
…cellular differentiation, cells all the same
Higher animals are…
…large and multicellular
Most higher animal cells are not…
…in close contact with the environment.
Higher animal cells need to be…
…specialised
Potential specialisation for higher animal cells?
Support
Heterotrophic Nutrition & Water uptake
Water, nutrient or gaseous transport
Protection
Gaseous exchange and Oxygen/Carbon dioxide transport
Locomotion
Sensory perception
Higher animal cells undergo…
…Cellular differentiation, cells not all the same, many different cell types, even more than in higher plants.
Microbes include…
simple animals and plants already covered, fungi, prokaryotes (eg bacteria), viruses.
In fungi, there is very little…
…cellular differentiation in the hyphae.
In fungi, there is…
…reproduction and fruiting bodies.
In fungi, cytoplasm and organelles (including nuclei and mitochondria…
…can ‘flow’ between cells in hyphae. Called a Syncytium.
Prokaryotes (bacteria) are in close contact with…
…the environment for gaseous exchange, water and import of nutrients.
Prokaryotes have no need for…
…different cell types.
In prokaryotes, there is very little or no…
…cellular differentiation, cells all the same
Viruses arent even…
…cells
VIruses only active in…
…host cells.
Viruses are present as…
…protein coated RNA or DNA in the Environment
