Lesson 1
what is the function of the cell membrane?
Controls what moves in and out of the cell.
How are plant and animal cells different or the same?
They are the same because they carry on life functions. They differ in shape and size.
Do you think horses and zebras are part of the same kingdom, phylum, class, order, and family?
Why?
Yes, because they have enough similarities and are both a type of horse.
Why is it important to keep plants healthy?
so they can continue to provide the products people need
What happens when light strikes a green leaf?
Plant cells make food.
Explain why animal cells do not have chloroplasts.
Animal cells obtain energy from the food they consume, they do not have chloroplasts that produce food.
What kind of organism is the diatom?
a unicellular organism
How many kingdoms of living things are there?
six
What things from the environment do plants need to survive?
water, sunlight, soil
Why is it important for people to eat food from every major food group?
to get the materials they need for growth and health
What do mitochondria do in both plant and animal cells?
Mitochondria breaks down food for energy production.
What identifies a plant or animal as a multicellular organism?
A multicellular organism has different kinds of cells that perform different functions.
How do scientists classify similar organisms?
They carefully compare cells, tissues, organs, and organ systems.
What kinds of seeds do people eat?
beans, nuts, rice, oats, peas, sunflower, and pumpkin seeds
Why do plants need energy?
to grow, reproduce, get rid of waste, and replace worn-out cells
Cells are the smallest units of a living thing that can carry out the basic processes of life.
How do plant tissues keep the plant alive?
Tissues take in water, nutrients, and air. Tissues also provide passageways for materials to move through the stem, roots, and the leaves.
How does a fungus survive?
It absorbs food from decaying or dead organisms in order to survive.
What kinds of plants would have deep root systems?
large trees
Why is it important for a plant to be able to store food?
The stored food can be used by the plant at a later time when the plant is not able to make food.
A structure that stores food, water, and wastes in plant and animal cells is a
Vacuole
Compare the organization in plants and animals.
Plants and animals both have cells, tissues, organs, and organ systems.
How is a fungus harmful to nature?
Wheat rust is a type of fungus that can destroy a field of wheat.
What materials are taken out of the plant cell?
food (sugar) and oxygen
Where do oxygen and sugar go when they enter the cell?
into the mitochondria
