Specialised Cells Flashcards
Palisade leaf cells are adapted for…
photosynthesis
Guard cells are adapted to…
open and close pores
Red blood cells are adapted to…
carry oxygen
Sperm and egg cells are specialised for…
reproduction
Palisade leaf cells are adapted by having…
Many chloroplasts near the the top
Tall shape with lots of surface area for absorbing CO2
Thin shape so many can fit in a leaf
Guard cells have a special…
kidney shape which opens and closes the stoma
Guard cells are able to…
Open the stoma when the plant has lots of water so gases can be exchanged
Close the stoma when the plant is short of water so less water vapour escapes
Guard cells have…
Thin outer walls and thickened inner walls
Guard cells are sensitive to…
light, and close at night to save water.
Red blood cells have a ____ shape for…
- concave
absorbing oxygen.
Red blood cells are full of…
haemoglobin (the pigment that absorbs the oxygen)
Red blood cells have no…
nucleus, to leave more room for haemoglobin.
The egg cell contains…
huge food reserves to feed the embryo.
Upon fusing with a sperm, the egg’s membrane…
instantly changes its structure to stop more sperm from getting in.
The sperm has…
A long tail
A streamlined head
A lot of mitochondria
Enzymes (to digest though the egg cell membrane)
