Plant and Animal Cells

Science Essential Question How does a system of living and non-living things operate to meet the needs of the organisms in an ecosystem? Science Essential Question

Something to Think About: How are the life processes carried out by an individual cell like the life processes carried out by living things?

In this lesson, we will… Distinguish between the basic structures and functions of plant and animal cells. Identify the major parts of plant and animal cells, such as the nucleus, cell membrane, cell wall, and cytoplasm. Compare and contrast basic structures and functions of plant and animal cells.

What are cells? A cell is the basic unit that makes up all living things. Cells are so small that you can see them only with a microscope. Cells carry out life processes.

Some things that have parts such as: A house A school Football stadium A hospital A car A clock

What are the parts of a school? Cafeteria Library Office Classrooms Bathrooms All Purpose Room Art Room Music Room Just as a school has parts, cells also have parts. Some parts are the same in both plant cells and animal cells.

Plant and Animal Cells These parts are used to carry out different life processes. Remember the life processes – (MRS GREN).

Checking In: All organisms, or living things, are made of __________. Cells Cool stuff unicellular

What is inside an animal cell? nucleus cytoplasm Cell membrane mitochondria vacuoles Animal Cell Organelles: Cell Membrane Cytoplasm Nucleus Mitochondria Vacuoles

What is inside an animal cell? Cell Membrane The cell membrane acts like a skin that holds the cell together. It is the outer layer of an animal cell. Cell membrane

What is inside an animal cell? Cytoplasm Cytoplasm is a jellylike material that fills the cell. The other parts of the cell float in the cytoplasm. cytoplasm

What is inside an animal cell? Nucleus: The nucleus in the control center of the cell. nucleus

What is inside an animal cell? Mitochondria: The mitochondria are the power sources of a cell They break down food to release energy. mitochondria

What is inside an animal cell? Vacuole: The vacuole is a storage container for food, nutrients, or wastes. Animal cells have many small vacuoles. Plant cells have a few large vacuoles. vacuoles

Checking In: Both plant and animal cells perform life processes by using ___________. Its parts Cell division organelles multicellular

Checking In: The cell’s control center is called the ________. mitochondria Cell membrane nucleus cytoplasm

Draw and label a diagram of an animal cell (Handout) nucleus cytoplasm cell membrane mitochondria vacuoles

What is inside the plant cell? vacuole nucleus chloroplasts cell membrane cell wall cytoplasm Plant cells have many of the same organelles as animal cells. often have a box-like shape are often a bit larger than animal cells have additional organelles that animal cells do not have mitochondria

What is inside the plant cell? vacuole nucleus chloroplasts cell membrane cell wall cytoplasm Plant cell organelles Nucleus Cell membrane Vacuole Cytoplasm Mitochondria Chloroplast Cell wall mitochondria

What is inside the plant cell? Cell wall Additional outer covering, outside the cell membrane Stiff structure Provides strength and extra support cell wall

What is inside the plant cell? Vacuole Unlike animal cells, plants usually have one LARGE central vacuole. Stores excess water to keep the plant from drying out Releases extra water when the plant needs it Provides extra support vacuole

What is inside the plant cell? Chloroplast Plants make their own food inside chloroplasts Green structure Energy from the sunlight is used to produce food for the plant inside the chloroplast Plants are green because they contain a green chemical, chlorophyll chloroplasts

What is inside the plant cell? Chloroplast Chlorophyll is able to use the energy in sunlight to make food Plants that do not have chloroplasts (with the green chemical chlorophyll), are not green. Chloroplasts are mainly found in the cells of leaves and stems of plants. chloroplasts

Checking In: The food making factory of plants is the ______________. mitochondria chloroplast nucleus cytoplasm

Checking In: The green chemical inside the chloroplast is called __________. cytoplasm chloroplast nucleus chlorophyll

Checking In: Chloroplast use energy from the ________ to make food. vacuole mitochondria sun chlorophyll

Checking In: Which organelle does the plant cell have but the animal does not? vacuole mitochondria cell wall cytoplasm

Checking In: Which organelle does the plant cell have but the animal does not? chloroplast mitochondria cell membrane cytoplasm

Checking In: Which organelle is the control center for the plant? chloroplast mitochondria nucleus vacuole

Checking In: Which organelle supplies energy for the cell? chloroplast mitochondria nucleus vacuole

Draw and label a diagram of a plant cell (Handout) vacuole nucleus chloroplasts cell membrane cell wall cytoplasm mitochondria
