7th Ch. 11 Cell Structure and Function Pre/Post Flashcard

Front

What are nucleic acids?

Back

Nucleic acids are macromolecules in cells that contain genetic information and are made of molecules called nucleotides.

Front

What process releases energy in cells?

Back

Respiration is the process that releases energy in cells, and it is almost the opposite of photosynthesis.

Front

What is passive transport?

Back

Passive transport is the movement of substances through the cell membrane without the use of cellular energy.

Front

What type of cells do palm trees and pandas have?

Back

Palm trees and pandas have eukaryotic cells, which contain membrane-bound structures.

Front

Who was NOT involved in discoveries about cells?

Back

Carl Sagan was NOT involved in discoveries about cells; he was known for his work in astronomy.

Front

What are the building blocks of nucleic acids?

Back

The building blocks of nucleic acids are nucleotides.

Front

What is the main function of respiration in cells?

Back

The main function of respiration in cells is to release energy from food.

Front

What is osmosis?

Back

Osmosis is a type of passive transport where water moves through a semipermeable membrane.

Front

What distinguishes eukaryotic cells from prokaryotic cells?

Back

Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.

Front

Name a process that requires energy in cells.

Back

Active transport is a process that requires energy to move substances against their concentration gradient.
