Cell review

Let’s Review

S7L2. Students will describe the structure and function of cells, tissues, organs, and organ systems.

a. Explain that cells take in nutrients in order to grow and divide and to make needed materials.

b. Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions.

c. Explain that cells are organized into tissues, tissues into organs, organs into systems, and systems into organisms.

EQ: How can I summarize what I have learned about cells?

Cells and Organelles

TRUE or FALSE?TRUE or FALSE?

All cells have a cell membrane and contain cytoplasm.

Eukaryotic, prokaryotic, plant, and animal cells ALL contain cytoplasm surrounded by a cell membrane (pg. 38).

TRUE or FALSE?TRUE or FALSE?

Prokaryotic cells have many membrane bound structures.

Eukaryotic cells have membrane bound structures.Prokaryotic cells do not (pg.39).

What is the structure that surrounds all cells, letting some substances in and out?

The Cell Membrane

The Cell Membrane allows very small

molecules, such as oxygen molecules, to

pass through it (pg. 38).

The jelly-like substance in a cell that holds all organelles in place is called:

Cytoplasm (pg. 38)

A.

B.

C.

D.

E.

Tough outer structure that gives some cells their box-like shape:

Cytoplasm

Chloroplasts

Cell Armor

Cell Membrane

Cell Wall

Cell Wall(pg. 39)

TRUE or FALSE?TRUE or FALSE?

The nucleus is the boss of the cell.

The Nucleus directs all cell activities and is usually the largest organelle in the cell (pg.40).

A.

B.

C.

D.

E.

Organelle which stores and releases energy for the cell to use:

Vesicles

Golgi Body

Cytoplasm

Nucleus

Mitochondria

Mitochondria(pg. 42).

What are the organelles called that produce proteins within the cell?

Ribosomes

Ribosomes are created in the nucleus and

produce proteins for the cell (pg. 42).

TRUE or FALSE?TRUE or FALSE?

Ribosomes are found in the Smooth Endoplasmic Reticulum.

Some ribosomes are found in the Rough Endoplasmic Reticulum, and some float freely in the cytoplasm of the cell (pg. 42).

The organelle responsible for the production of some hormones and lipids:

Smooth Endoplasmic Reticulum(pg. 43)

A.

B.

C.

D.

E.

Organelle that sorts substances and packages them into vesicles for transport:

Smooth ER

Vacuole

Mitochondria

Yupeaestacin

Golgi Body

Golgi Body (pg. 43).

Organization of Life

Match each term to the correct definition:

Organism

The Cell

Tissue

Organ

Organ System

• Several systems work together to perform life functions (pg. 45)

• Two or more tissues that work together (pg. 45)

• Smallest Unit of Life (pg. 38)

• A group of cells that work together to do one job (pg. 45)

• Group of organs that work together (pg. 45)

Cellular Transport

How the cell moves substances into and out of the cell.

A.

B.

C.

D.

E.

Cellular transport that requires no input of energy:

Funnels

Protein Transport

Membrane Transport

Active Transport

Passive Transport

Passive Transport (pg. 74)

When substances move from an area of high concentration to an area of low concentration, this is called:

Diffusion

Diffusion:When substances naturally move from

an area of high concentration to an area of low concentration across the

cell membrane (pg. 75).

TRUE or FALSE?TRUE or FALSE?

Osmosis is the diffusion of glucose (sugar).

Osmosis is the diffusion of water (pg. 76).

What is it called when there is no longer and area of high or low concentration on either side of the cell membrane?

Equilibrium

A.

B.

C.

D.

E.

When a substance is too large to move across the cell membrane, it must rely on transport proteins in a process called:

Helper Transport

Transport Diffusion

Active Diffusion

Helper Diffusion

Facilitated Diffusion

Facilitated Diffusion (pg. 77)

TRUE or FALSE?TRUE or FALSE?

Active transport requires energy.

Active transport requires energy because it involves moving substances from low to high concentrations.

When a cell uses the cell membrane to pull a substance into the cell:

Endocytosis (pg. 78)

When a cell releases substances outside of the cell using vesicles:

Exocytosis (pg. 78)

TRUE or FALSE?TRUE or FALSE?

All activities in an organism involve chemical reactions.

The total of all chemical reactions in an organism are called metabolism (pg. 81).

Organelles which produce glucose (food) in most plant cells.

Chloroplasts

Chloroplasts convert light energy into chemical energy through the process of photosynthesis

(pg. 82).

+ O + SUNLIGHT -----› + 6 Carbon dioxidemolecules

1 Water molecule

Light energy

1 Glucose/sugarmolecule

6 Oxygenmolecules

A.

B.

C.

D.

E.

The process in which animal cells break down food for energy is called:

Assisted Transaction

Active Transport

Cellular Production

Cellular Globalism

Cellular Respiration

Cellular Respiration (pg. 83).

By engaging in a discussion and writing down

important information.
