Red Blood Cell •

Small

and

flexible

to fit through tiny tubes.

• NO

nucleus

to make more room for

more oxygen

Nerve Cell

Long

and

branching

arms to send

messages

quickly from any part of the body to the

brain.

Muscle Cell •

Long

and

skinny

to contract and extend for movement. • Lots of

nuclei

to help large cell communicate.

• Lots of

mitochondria

because cells need lots of

energy.

White Blood Cell Can change

shape

to fit between tissues to

find

and

fight

infections.

Leaf Cell Has

chloroplasts

to change light energy into food

(photosynthesis).

Root Cell • Many large

vacuoles

to soak up and

store

water for the plant.

• NO

chloroplasts

because there is no

light for photosynthesis.
