The smallest unit of a living thing that can carry out the basic processes of life
100
How do animals get food and energy if they do not have cells that produce food?
The food they consume is turned into energy that is transported through the body
100
What are the 6 life processes all living things must be able to do?
All living things experience growth, response, reproduction, nutrition, respiration, and excretion
100
What are the two groups of the animal kingdom?
Invertebrate and Vertebrate
100
What is the first thing scientists would want to know about a new animal in order to classify it?
Scientists would want to know whether or not the animal has a backbone
200
What best describes the cell membrane?
a. stores food, water, and wastes
b. turns food into energy
c. a layer around the outside of the cell
d. produces food for the cell
C. a layer around the outside of the cell
200
Why do plant cells have one large, central vacuole?
Vacuoles store extra water and help support the plant
200
Which of the following life processes has the ability to break down food into energy?
Respiration
200
What is a classification system?
Classification system puts organsims into groups based upon their similarities
200
In the classification system, which is the largest group? the narrowest?
Kingdoms – largest, Species - narrowest
300
What is the purpose of the mitochondria in animal cells?
Breaks down food and turns it into energy for the cell to use
300
What is the purpose of the chloroplasts in a plant cell? Why do animal cells not have this organelle?
Chloroplasts turn energy from sunlight into food. Animal cells obtain energy from the food the organism consumes.
300
What are organs made of? Provide an example of an organ found in a plant and an organ found in an animal.
Different kinds of tissue.
Plant – leaf, roots, stem
Animal – brain, heart, lung
300
A scientist finds a unicellular organism that consumes decaying materials. In which of the following kingdoms should the organism be classified?
a. animal
b. plant
c. fungus
d. protist
Fungus. A fungus is a unicellular or multicellular organsim that absorbs food from decaying or dead organisms
300
Plants are classified into two major categories. What are these two groups? Describe each group.
Vascular – vascular tissue, can grow tall, transport materials throughout the plant
Non-vascular – no vascualar tissue, grow close to ground, no true roots
400
Which of the following is true about all animals?
They get their energy from eating other organisms
400
What is the importance of a cell wall in a plant cell?
Plant cells have an additional layer around the outside of the cell. Cell wall protects plant cells and gives them their shape. The cell wall lets food and wastes move in and out of the cell, but its main job is to provide extra support.
400
Describe a tissue. What is an example of tissue found in a plant? and in an animal?
A group of similar cells that do the same job in an organism. Plant – vascular tissue – carries water and minerals from the plant’s roots through the stem to the leaves. Also flesh of a fruit. In an animal – legs have muscle tissue which allow you to move your legs.
400
Which of the following organisms is most likely likely a protist?
a. multicellular organism with vascular tissue
b. unicellular organism without a distinct nucleus
c. unicellular organism that can produce its own food
d. multicellular organism with a backbone
C. Unicellular organism that can produce its own food - plant-like. Protists have a distinct nucleus
400
What is the function of vascular tissue?
The vascular tissue in an plant moves food, water, and waste to different parts of the plant through small tublar vessels.
500
Can a cell function without a nucleus? Explain
The other structures in the cell would not function properly without the nucleus to control all cell activities.
500
How might the vacuole in a desert plant be different from a flowering plant in our backyard?
Desert plants need to store a lot of water because they live in a dry environment, while flowering plants receive water each day . . . hopefully : )
500
Which of the following organisms does not have a nucleus?
bacteria
500
What are the six kingdoms? List one trait of each kingdom
Plant – vascular and non-vascular
Animal – vertebrate and invertebrates
Fungi – absorbs food from decaying organisms
Protists – plant-like, animal-like, fungi-like
Ancient bacteria– found in hot springs, oldest living organism
True Bacteria – can cause disease
500
What are multicellular organisms made up of? Provide an example of each.
Cells - plant or animal
Tissue - vascular tissue, muscle tissue
Organs - stem, leaf, - heart, lungs
Organ system - root system, digestive system
Organism - lily, lion
