Life Science 5: Milestone Cell Review

Which of these would you find in a plant cell but NOT in an animal cell?

• nucleus

• cytoplasm

• chloroplast

• mitochondria

Each part of a cell has a particular job to do. For example, a vacuole's job is storing water, nutrients, and wastes. Which pairing correctly matches a cell part with its job?

• cell membrane: directing all cell activity

• mitochondria: releasing energy for cell use

• nucleus: shaping cell and hold cell parts

• cytoplasm: surrounding the cell

Which organism is made of only one cell?

• a human

• a fish

• a butterfly

• an amoeba

A scientist looks at a cell under a microscope and charts her findings:

Cell Part: Observation

cell membrane: yes

nucleus: yes

mitochondria: yes

chloroplast: yes

cell wall: yes

What kind of cell does the scientist conclude this is?

• amoeba

• animal

• bacteria

• plant

Carlos is studying a cell under a microscope. He observes the structure that directs the cell's activities. What is it called?

• cell membrane

• chloroplast

• cytoplasm

• nucleus

Jade uses a microscope to look at a plant and animal cell. She draws a sketch of what she sees. What do her sketches show?

• Only the animal cell has chloroplasts.

• The plant cell doesn't have a cell wall.

• The animal cell has more than one nucleus.

• The plant cell has as thicker outer covering than the animal cell has.

Tam wants to examine some plant cells under a microscope. Of these things, which should he do first?

• draw a picture of what he observes

• think up his procedures

• look for the nucleus

• add food coloring

Mara uses a microscope to determine whether a particular cell came from a plant or animal. Which of these would prove it came from a plant?

• cell membrane

• cell wall

• nucleus

• vacuole

When looking under a microscope, a young 5th grade science student determined he was looking at an animal cell. Which of the following helped him make this determination?

• The cell was rectangular in shape

• The cell was triangular in shape.

• The cell was round in shape.

• The cell was octagonal in shape.

This is the basic unit of structure of a living thing.

• organism

• membrane

• cell

• tissue
