Warm-Up The Function of Organelles

Lesson Objectives

By the end of this lesson, you should be able to:

? Identify the organelles found within a cell.

? Describe the functions of each organelle within the cell.

Science Practice: Construct charts, graphs, and tables to organize data .

W2K

Words to Know

Fill in this table as you work through the lesson. You may also use the glossary to

help you.

cell membrane

an organelle that provides a protective layer around a cell

and controls what enters and leaves the cell

cell wall

a strong, supporting layer around the cell membrane

in plants, algae, and some bacteria

centrioles

a pair of cylindrical structures that are located near the

nucleus and help to organize cell division

chloroplast cytoplasm

a specialized organelle in green plant cells and some other photosynthetic organisms that captures the energy

from sunlight and converts it into chemical energy

a jellylike substance that supports and protects organelles in a cell

Words to Know

endoplasmic an organelle that moves reticulum substances through a cell

proteins

and other

an organelle that packages and distributes

Golgi apparatus

proteins received from the endoplasmic reticulum

an organelle that contains digestive enzymes that lysosome

break down waste material and debris in a cell

an organelle that breaks down sugar molecules to supply mitochondrion

energy to a cell

an organelle that directs cell activity, acting as the nucleus

control center

ribosome an organelle that produces proteins for a cell

What are the roles of different organelles in a cell?

Animal and plant cells contain many of the same

organelles

.

Plant cells also contain two organelles not found in animal cells:

the cell wall and chloroplasts .
