Q

specialized cells- root hair cells

plant kingdom

A

plant cell
absorbs water and mineral ions from earth
large surface area- long structure, thin walls
soaks up water from soil by osmosis
VACUOLE
CELL WALL
CELL MEMBRANE
CYTOPLASM
NUCLEUS
NO CHLOROPLASTS- because underground so dont need to photosynthesize

Q

specialized cells- red blood cell

animal kingdom

A

animal cell
contains haemoglobin to carry oxygen around the body
BICONCAVE STRUCTURE-bigger surface area, enables oxygen to be carried around easier
thinner outer membrane- allow oxygen to diffuse through easily
NO NUCLEUS- more space for haemoglobin
CELL MEMBRANE
HAEMOGLOBIN
BICONCAVE STRUCTURE
