Dichotomous keys, Cells and genetics:​

7.11A, 7.12D, 7.14C

Multiple Choice

What is a dichotomous key used for in science?

• To organize biomes
• Classify organisms
• Identify bacteria only
• None of these

Multiple Choice

Using this dichotomous key, identity the name of the circled fish.

• band-tail puffer
• spotted goat fish
• peacock flounder
• trumpet fish

​Cytoplasm

​

​Jelly-like structure. Keeps all the organelles together in the cell.

​​Nucleus

'Brain' of the cell. Control all cell activities.

​​Cell Wall

Layer of non living material that surrounds the cells of plants.

Only in plant cells.

Gives plants it's shape. It helps protect and support the cell.

​Cell Membrane

All cells have it. It is the outside boundary that separates the cell from the environment.

​

​

​

​

"Hey border patrol let the water and food inside we need need them, but don't let the Corona Virus in we don't need that."

​Chloroplast

Only found in plant cells. Allows the cell to make its own food.

Mitochondria

"Powerhouses" of the cell because they produce most of the energy the cell needs to carry out its functions. Rod shaped organelles.

Vacuole

Storage of the cells. Plants cells have one large vacuole. Animal cells have many large vacuole.

Multiple Choice

What is the Function and Structure of the Nucleus?

• Structure: The Jelly-like material that is within the cell and is enclosed by the cell membrane.

  Function: Converts light energy into chemical energy

• Structure: A large, oval-shaped structure that is enclosed in a membrane.

  Function: Contains the genetic material responsible for controlling the activities of the cell

Multiple Choice

What is the Function and Structure of the Vacuole?

• Structure: Large, round sac that is filled with fluid

  Function: Stores water, food, or waste materials for the cell

• Structure: Bean- or peanut-shaped with internal membranes

  Function: Gives support to the organelles within the cell

Multiple Choice

What is the Function and Structure of the Mitochondria?

• Structure: Bean- or peanut-shaped with internal membranes.

  Function: Breaks down sugars to release energy in a form usable by the cell; the powerhouse of the cell.

• Structure: Green, oval-shaped structure that contains chlorophyll

  Function: Regulates the passage of materials in and out of the cell, protects and gives some structure.

Multiple Choice

What is the Function and Structure of the Cell Membrane?

• Structure: A porous, thin tissue that forms the outer surface of the cytoplasm.

  Function: Converts light energy into chemical energy.

• Structure: A porous, thin tissue that forms the outer surface of the cytoplasm.

  Function: Regulates the passage of materials in and out of the cell, protects and gives some structure.
