What are the characteristics of eukaryotic cells?• Eukaryotic cells differ depending on their structure
and function.
• Structure is the arrangement of parts. Function is the activity the parts carry out.
• All eukaryotic cells have a nucleus and membrane-bound organelles and common structures that protect and support the cell.

What are the characteristics of eukaryotic cells?• Cell membranes act as a barrier for cells. They
regulate what enters and leaves the cell.
• Throughout the cytoplasm of eukaryotic cells is a cytoskeleton, or network of protein filaments that gives shape and support to cells.
• The cytoskeleton helps in cell division and in movement.

What are the characteristics of eukaryotic cells?• The nucleus contains the cell’s genetic material or
DNA.
• Instructions for creating proteins are sent through pores in the nuclear membrane by DNA.

What organelles are found in plant and animal cells?• Cellular respiration is the process by which cells
get energy by breaking down food.
• Mitochondrion is an organelle where cellular respiration occurs.
• Mitochondria have their own DNA and two membranes.

What organelles are found in plant and animal cells?• Ribosomes are organelles that make proteins by
putting together chains of amino acids.
• Ribosomes do not have a membrane.
• Some ribosomes are free, and others are attached to the endoplasmic reticulum.

What organelles are found in plant and animal cells?• The endoplasmic reticulum, or ER, assists in the
production, processing, and transport of proteins and in the production of lipids.
• Rough ER has ribosomes attached to its membrane.
• Smooth ER makes lipids and breaks down toxins.

What organelles are found in plant and animal cells?• The Golgi complex packages and distributes
materials in a cell.
• Lipids and proteins from the ER are delivered to the Golgi complex to be modified for different jobs.
• Vesicles of pinched-off Golgi complex membrane carry products out of the cell or to other parts of the cell.

What additional parts are found in plant cells?• In plants, the cell wall is a rigid structure that
surrounds the cell membrane, providing support and protection to the cell.
• Some fungi, archaea, bacteria, and protists also have cell walls.

What additional parts are found in plant cells?• A vacuole is a fluid-filled vesicle found in the cells
of most animals, plants, and fungi.
• Plant cells have large central vacuoles that store water and help support the cell.

What additional parts are found in plant cells?• A chloroplast is an organelle where
photosynthesis occurs.
• Photosynthesis is the process in which cells use sunlight, carbon dioxide, and water to make sugar and oxygen.
• Chloroplasts are green because of green pigment called chlorophyll, which absorbs solar energy.

Introducing: The Animal Cell
Copyright © Houghton Mifflin Harcourt Publishing Company
What additional part is found in animal cells?• Lysosomes are organelles in animal cells that
contain digestive enzymes.
• These enzymes break down worn-out or damaged organelles, waste material, and foreign invaders of the cell.
• Some of the materials are collected in vacuoles.
