Cell Structures and Organelles

QuestionAnswer
This structure surrounds the cell. Cell Membrane
A gel-like liquid inside the cell. Cytoplasm
An organelle that releases energy from food molecules for the cell to use. Mitochondria
Give plants their green color, and produce sugar. Chloroplasts
A long molecule that is the genetic material for a cell. DNA
A type of organelle that make proteins. Ribosomes
A protective, flexible barrier that controls which materials enter and leave the cell. Cell Membrane
Helps maintain cell shape. Cytoplasm
Releases energy for cell use. Mitochondria
__ found in plant cells only. Chloroplasts
Short for deoxyribonucleic acid. DNA
An organelle that does not have a membrane. These organelle make proteins. Ribosome
This organelle provides usable energy to the cell. Mitochondria

Only plant cells have a cell wall, chloroplasts, and a large __. Vacuole
In what part of a cell is hereditary information found? Nucleus
The function of the ___ is to control substances that enter and exit the cell Cell Membrane
The function of the ___ is to provide support for the cell. Cell Wall
___ is a gel-like substance, found in both plant and animal cells. Cytoplasm
How are chloroplasts in plant cells and mitochondrion in animal cells similar? Both are energy factories
Students observed cells under the microscope. They observed that the cells had a cell wall, cell membrane, nucleus, and many chloroplasts. Which observation helps students identify the type of cell observed? The presence of chloroplasts means that the cells are from a plant.
