blood smear

identify A and B

lighter colour cells = erythrocytes

darker colour cells = neutrophils

turn

label A & B

A - vacuole

B - nucleolus, not nucleus

turn

name A-F

A - rough endoplasmic reticulum

B - plasma membrane

C - ribosome

D - golgi apparatus

E - secretory vesicle

F - mitochondria

turn

A - glomerulus

B - bowman's capsule

turn

name W, X, Y, Z

W liver / hepatic

X pancreas / pancreatic

Y skeletal / striated , muscle

Z cardiac muscle

turn

what stageisAin

A - metaphase

turn

name A-D

A - glomeruli

B - PCT

C - renal artery

D - bowman's capsule

(these are my guesses as the mark scheme don't have the actual answers)

name A - E

A - erythrocyte

B - platelet

C - neutrophil (lobed nucleus)

D - lymphocyte (large nucleus, takes up most of cell)

E - protist

how do you distinguish between a monocyte and lymphocyte under a microscope?

monocyte has a kidney bean nucleus, lymphocyte have a large nucleus that takes up most the cell

turn

name A-F

A - renal vein

B - renal artery

C - renal pyramid

D - renal pelvis

E - renal medulla

F - renal cortex

turn

name A & B

A - bowmans capsule

B - glomeruli

how do you distinguish between the PCT and DCT under a microscope?

PCT will have microvilli whereas DCT will not
