Move, respire, resond to stimulii, grow, reproduce, excrete and survive on nutrients if it doesnt do one of these things its not classified as alive thats what ive been taught but my biology teachers a bit of a mong ..... all things move though it may just be the cells inside them so we cant see teh movement .
no... 😕 there are just three things: It must be made of cells, respond to stimuli (both external stimuli and internal stimuli count), and be able to reproduce on its own
Like plants are living but they don't move, nor do they breathe, nor do they genarate fecal matter, nor do they survive on true "nutrients"
To be considered an animal, an organism must be:
1. Eukaryotic (having cell nuclei)
2. A consumer (consumes other organisms for energy rather than using sunlight)
3. Multicellular
4. Posessing free movement (growing, as with a plant doesn't count as free movement, nor does the type of movement a Venus fly trap is capable of--basically it has to be able to get up and move around)
5. Not posessing cell walls
Venus fly traps are plants. They meet all of the criteria for being plants. The only thing unusual about them is that they can digest other organisms for food. However, they can still produce their own food, making them plants. That and the fact that you can actually see them move, but as I said before, it still doesn't count as free movement since they can't pick up and move to a different place if they run out of resources where they are.
Erm well that was just my limited view of biology .... being wrong.
OK so those where the 7 main characteristics i learnt you r probably right i just wanted to point out plants do move - they grow towards the sun (free movement), respire doesnt mean breathe it is the action of releasing energy from food which a plant does (photosynthesis) and they do survive on nutrients (if i could be bothered i could find out which ones but just too lazy) which they take up from the soil.
But your probably right about the classifying of an animal thing my biolagy teachers a complete prat soooooo my biology knoledge aint that great.
