Biology Characteristics of Life
What is the simplest level at which life may exist?
Cell
Identify the feature of life that is illustrated by each of the following statements. "That owl's night vision allows it to see the movement of mice on even the darkest night."
Development or adaptation
Identify the feature of life that is illustrated by each of the following statements. A giraffe uses its long neck to eat from the high branches of a tree.
Development or adaptation
Identify the feature of life that is illustrated by each of the following statements. "Eat a good breakfast and you will be able to run longer."
Heterotroph
Identify the feature of life that is illustrated by each of the following statements. Your body normally maintains a temperature of 98.6OF.
Homeostasis
Must EVERY member of a particular species (one kind of organism) be able to reproduce in order for the species to survive? Explain why or why not.
No because if only a couple can reproduce then they will still have the continuation of the species.
Identify the feature of life that is illustrated by each of the following statements. is another name for "living thing."
Organism
What is the name of the process that plants use to make their own food using energy from the sun?
Photosynthesis
Identify the feature of life that is illustrated by each of the following statements. "Single-celled organisms live in the pond behind school."
Unicellular
What is the difference between unicellular and multi cellular organisms?
Unicellular is consisting only one cell and multi cellular is consisting multiple cells.
Identify which of the following organisms are reproducing sexually and which are reproducing asexually. Bacteria Hydra Sea Urchin
asexual asexual sexual
Are all cells alike?
no
Do multicellular organisms DEVELOP?
no
Do unicellular organisms DEVELOP?
no
Determine if each of the following describes a living or nonliving thing. a dinosaur fossil
nonliving
Determine if each of the following describes a living or nonliving thing. lightning
nonliving
The scientific term for a living thing is a(n)
organism
Reproduction is NOT essential for the survival of an individual ________ but is essential for the survival of the _______.
organism species
All living things are
organized
Multicellular organisms can be organized into what other levels?
tissues organs systems
What would happen if all individuals in a species were sterile (not able to have babies)?
After a while the species would die off.
What are some environmental factors (stimuli) that organisms respond to?
Air, water, weather, and temperature.
What is the difference between an autotroph and a heterotroph?
Autotroph get their energy from the sun to make their food. Heterotroph get their energy from the food they eat.
Define energy.
Energy is the ability to make things change.
What is meant by extinction?
Extinction is when the entire species has died off.
Identify the feature of life that is illustrated by each of the following statements. "My dog has become much less clumsy now that he is a year old."
Growth
Identify the feature of life that is illustrated by each of the following statements. "That boy shot up five inches in only one year."
Growth
What is the difference between growth and development?
Growth is increase in the amount of living material and formation of new structures(increase of size and mass). Development is the changes that take place in your life.
Describe homeostasis.
Homeostasis is the ability of mammals and birds to regulate body temperature.
Give two examples from the reading of how living things respond to changes in their environment.
If you go outside on a bright summer day it will cause you to squint. When a dog barks it will cause you to turn your head quickly.
Why is energy important to a living organism?
It powers life processes.
If light is applied to a human eye, how does it respond?
It squints.
What are two internal factors that organisms respond to?
Level of water and nutrients.
List Characteristics of ALL LIVING THINGS
Living Cells Reproduction Use of Energy Growth Development Homeostasis Use of the Environment One or more cells
What surrounds a cell and separates it from its environment?
Plasma Membrane
Identify the feature of life that is illustrated by each of the following statements. "Our cat had a litter of kittens yesterday."
Reproduction
Define reproduction
Reproduction is the production of an offspring for life to continue.
Identify the feature of life that is illustrated by each of the following statements. "When that car pulled in the driveway, my cat ran to hide under the porch."
Respond to the Environment
Name and define the two basic kinds of reproduction.
Sexual is when it requires two cells. Asexual single organism can reproduce.
How do all organisms begin life?
Single cells
How is the growth of a living thing different from the growth of a nonliving thing?
The growth of living things are grown by their cells. Nonliving things are grown by structure.
Give an example of a unicellular organism
bacterium protist amoebas paramecia
Give an example of a multi cellular organism
dog trees
