Specialised cells Flashcards
how are palisade (plant) cells differentiated?
they contain lots of chloroplast as they do most of the photosynthesis in a leaf
how are red blood cells specialised?
dont have a nucleus so theres more space for oxygen
have a biconcave disc shape that provides a large surface area so more oxygen can get absorbed
how are the ciliated epithelial cells specialised?
have little hairs called cilia that can waft mucus which has trapped dust and bacteria back up the throat
how are sperm cells specialised?
has a flagella so it can swim to the egg
has a streamlined shape so it can swimm faster
has lots of mitochondria which gives the cell lots of energy to swim to the egg
how are guard cells specialised
have a stomata that allows gases to pass through
how are white blood cells specialised?
it can change its shape so phagocytosis (surrounding and engulfing the cell )can occur
it can produce antibodies and antitoxins to destroy bacteria
how are root hair cells specialised?
has a large surface area so it can absorb as much water as possible
no chloroplasts as its underground so theres no light for photosynthesis
how are nerve cells specialised?
they have a long axon to carry impulses
the axon is insulated well
