I am the most basic building block of life.
What is a cell?
What is a "nucleus?"
This process uses sunlight, water, and carbon dioxide to make food and oxygen. (Autotrophs do this). What is the process called?
What is photosynthesis?
True or false: how an organism maintains a constant temperature is an example of homeostasis.
True! Maintaining temperature is an example of maintaining a constant internal environment.
True!
I am the molecule that contains the genetic information for all living things.
What is DNA?
Humans, plants, and all multicellular organisms have this type of cell.
What is a eukaryotic cell?
What is "food?"
True or false: homeostasis only relates to temperature.
False! There are lots of other aspects of an organism's internal environment (e.g., maintaining salt, water concentration, etc.) which are also examples of maintaining homeostasis.
True or false: an apple is biotic.
True! An apple is a part of a living thing.
All organisms need me to be alive. Plants get me from the sun, and animals get me from eating.
What is energy?
Bacteria and other unicellular organisms do not have a nucleus, making them a __________ cell.
What is a "prokaryotic" cell?
The root "hetero" means ______.
What is "other/different?"
True or false: a person urinating to keep a constant water level is an example of maintaining homeostasis.
True!
True or false: a skeleton is biotic.
True! Even if part of a dead organism, if it was formerly part of a living thing, it is "biotic."
I am how offspring are made.
What is reproduction?
Viruses cannot be considered true cells because they lack ___________? (Multiple answers apply)
What are: ________
-ribosomes
-DNA
-cell membrane
Animals are an example of _______trophs because they need to eat to live.
What are "heterotrophs?"
True or false: if an organism fails to maintain homeostasis over a long enough time, it will get sick/ and or die.
True! Failure to maintain homeostasis can result in sickness or death.
True or false: a fossil is biotic.
False. A fossil is a rock, not a bone.
Sweating, shivering, and anything that helps an organism maintain a constant internal environment.
What is homeostasis?
Name one trait that prokaryotic and eukaryotic cells have in common. (Multiple answers accepted)
What are:
-ribosomes
-DNA
-cytoplasm
-cell membrane
Some bacteria can do photosynthesis (e.g., cyno-bacteria), and some cannot. Based on this bacteria are both _____trophs and ______trophs.
What are autotrophs and heterotrophs?
The root "homeo" means ___________ and "stasis" means ___________.
Homeo = same/ similar
stasis = state
True or false: a virus is biotic.
False! A virus is non-living/ never was alive, so it is abiotic.
