Cell Introduction

What is the function of the nucleolus inside a cell's nucleus?

• It is a structure where ribosomes are made.

• A network of membranes that produces many substances.

• A clear, gel-like fluid that fills the nucleus.

• A green pigment that makes plants green.

What happens during osmosis?

• Water molecules move from lower to higher concentration through the cytoplasm.

• Water molecules move from a higher to lower concentration through a selectively permeable membrane.

• Water molecules are engulfed and vesicles are formed.

• Water molecules does not remain homeostasis.

• Ribosome

• Centriole

• Organelle

• Cytoplasm

• Eukaryotes

• Cells

A student listed some characteristics of a structure presented in an animal cell:

• It completely surrounds the cytoplasm of a cell.

• It controls the movement of substances in and out of the cell.

• It separates the contents from the external environment.

Oxygen is moving into an animal cell. Which term best describes this process?

• Diffusion

• Osmosis

• Active transport

• Endocytosis

How do materials pass into and out of the nucleus?

• In the process of endocytosis

• By flowing through the cytoplasm

• From the ER to the golgi body

• Through pores in the nuclear envelope

Cells contain structures that perform specific functions. Examine the diagram of the cell. Which structure is the golgi apparatus?

• A

• G

• B

• F
