Gr6 Cell Structure & Function 6-LS1-2

Where do animal cells get the molecules, such as proteins, that they use for growth, repair and other life processes?

• The animal takes in materials from the environment, and the cells use the materials without changes.

• The small intestine makes them from food that the animal ingests.

• The cells make them from materials the animal takes in from the environment.

• The lungs make them from gases the animal takes in when it breathes.

A ________ is a rigid layer that surrounds a plant cell, providing structural support.

• chloroplast

• nucleus

• cell wall

• cell membrane

All organisms are made up of cells. These cells are responsible for performing many functions in the body, such as making proteins and producing energy. In order to perform these functions, the cells need

• electrical energy.

• nutrients from food.

• information from books.

• only water.

Both animal and plant cells are eukaryotic cells. What is the difference between animal and plant cells?

• Plant cells have cell walls and chloroplasts, but animal cells do not.

• Plant cells have nuclei and mitochondria, but animal cells do not.

• Animal cells have nuclei and mitochondria, but plant cells do not.

• Animal cells have cell walls and chloroplasts, but plant cells do not.

The cell membrane is a flexible structure that surrounds both plant and animal cells. The arrangement of molecules within the cell membrane makes it semi-permeable. That is, the cell membrane allows some substances to easily diffuse into and out of the cell, but it prevents the diffusion of other substances. The cell wall is a rigid structure that surrounds plant cells. The materials found in the cell wall protect the plant cells and give plants structural support. Which conclusion can be made given the information?

• The function of a cell organelle can change over time.

• The functions of most cell organelles are hindered by their structures.

• The structure of a cell organelle is directly related to its function.

• The structures of different types of cell organelles are similar.
