Slides on Cell Parts and Function

Cell Transport & Homeostasis, with support in Energy, Cell Types, and Cell Structures : 11A, 5C (5B), 5D

Objective: By the end of this lesson, I'll be able to explain how diffusion, osmosis, and active transport work, and predict how molecules move in and out of cells in various situations.

Note: Please skip to "Homeostasis" slide for class, but review all previous slides

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
