Levels of Organization
What is the smallest level of organization in a living organism?
Organelles
What characteristics of life involve photosynthesis and eating to survive?
Using energy
Which type of cell does not have a nucleus?
Prokaryotic
What does the cell membrane do?
Controls what goes in and out of the cell
Which cell structure is responsible for photosynthesis?
Chloroplast
Which level of organization consists of a group of cells working together to perform a function?
Tissues
Name one characteristic of life that helps maintain internal balance.
Homeostasis
Which type of cell is multicellular and has many organelles?
Eukaryotic
What organelle is known as the “powerhouse” of the cell?
Mitochondria
What is the function of the cell wall in plant cells?
It gives structure and shape to the cell
Put these levels of organization in order from smallest to largest: tissues, cells, organs.
Cells, Tissues, Organs
Which characteristic of life allows organisms to produce offspring?
Reproduction
True or False: Prokaryotic cells have DNA.
True
What organelle controls what happens inside the cell and holds DNA?
Nucleus
Name one structure found in plant cells but not in animal cells.
Chloroplast or Cell Wall
What is the level of organization where organ systems work together?
Organism
What characteristic explains how organisms evolve?
Ability to adapt
What type of cells are considered simple and unicellular?
Prokaryotic
What structure creates energy for the cell to use?
Mitochondria
True or False: Both plant and animal cells have a cell membrane.
True
Name all six levels of organization in order from smallest to largest.
Organelles, Cells, Tissues, Organs, Organ Systems, Organism
Identify all seven characteristics of life.
Growth, use energy, respond to their environment, reproduce, maintain homeostasis, adapt, can be unicellular or multicellular
What cell is Multicellular has a nucleus, and many organelles
Eukaryotic
What are the three structures you need to label on a cell diagram?
Cell Membrane, Nucleus, Mitochondria
Why do plant cells have a cell wall and chloroplasts but animal cells do not?
Plant cells need chloroplasts for photosynthesis and a cell wall for structure.
