Cell Structure & Function

Cell Transport & Homeostasis

Multiple Choice

All cells -----

• come from other dead cells

• come from other living cells

• crystallize out of the air

Multiple Choice

What is the basic structural and functional unit of all living things?

• atom

• cell

• bacteria

• animalcules

Multiple Choice

All living things are made up of...

• cells

• tissues

• organ

• organ systems

Multiple Choice

What type of cell has a nucleus?

• eukaryotic

• prokaryotic

Multiple Choice

Plants and animal cells are examples of ___ cells

• prokaryotic cells

• eukaryotic cells

Multiple Choice

A single-celled organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane -bound organelle .

• Prokaryote

• Eukaryote

• Nucleus

• Single-celled organism

Multiple Choice

A rigid layer that lies outside the cell's membrane is...

• Cytoskeleton

• Cilia

• Cell Wall

Multiple Choice

I am the outer most layer of an animal cell. What am I?

• cell wall

• nucleus

• cell membrane

Multiple Choice

Directs all cell activities through the DNA located there.

• Endomembrane System

• Nucleus

• Ribosomes

• Mitochondria

Multiple Choice

Name structure #5.

• rough ER

• nucleus

• vesicle

Multiple Choice

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport

Multiple Choice

Why are diffusion and osmosis important to cells?

• It allows them to take in materials/substances without using energy.

• It allows them to reproduce.

• It allows them to absorb sunlight.

Multiple Choice

Which diagram best shows the end result of diffusion?

• F

• G

• H

• J

Multiple Choice

Active transport requires _____ to move materials across the cell membrane.

• proteins

• sunlight

• oxygen

• energy

Multiple Choice

Solutes move against the concentration gradient, therefore energy is needed.

• Passive Transport

• Active Transport

Multiple Choice

How do organisms get the energy they need?

• Plants get energy from fertilizers and animals get energy from drinking water.

• Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.

• Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.

Multiple Choice

What organelle is called the "powerhouse" of a cell?

• Endoplasmic Reticulum

• Nucleus

• Mitochondria

• Nucleolus

Multiple Choice

In what way is photosynthesis and respiration related to each other?

• The reactants of photosynthesis are the reactants of respiration.

• The products of photosynthesis are the reactants of respiration.

• The products of photosynthesis are the products of respiration.

Multiple Choice

I am only found in a plant cell. What am I?

• cell wall

• mitochondria

• cytoplasm

• chloroplast

​Each structure allows the virus to attach or protect itself to better implant and infect a cell.

Multiple Choice

The reason that viruses are considered to be nonliving is because

• They are not cellular
• They cannot reproduce on their own
• They cannot make proteins
• all of the above

Multiple Choice

What do all viruses need to reproduce?

• They need host genetic material

• They need a host cell

• They need bacteria

Multiple Choice

The projections on the surface of this virus allow the virus to —

• move inside a host cell

• attach to a host cell

• control a host cell’s DNA

• signal other viruses to infect a host cell
