Stuart Biology Chapter 3
Example of a prokaryotic cell
Bacteria
The smallest unit of life
Cell
The structure that regulates what enters and exits the cell.
Cell membrane
The protein that most of the food and waste materials pass through in a cell.
Channel protein
Organelles associated with photosynthesis
Chloroplasts
Short, hairlike structures that protrude from cells, and allow for movement.
Cilia
The function of the cell membrane
Control what goes in and out of the cell.
The organelle that helps maintain homeostasis by moving substances from one part of the cell to another.
Endoplasmic reticulum
All living things that are not bacteria are eukaryotes.
False
Most living prokaryotes are multicellular protists.
False
The cell membrane contains DNA.
False
The cells of animals are prokaryotic.
False
The only difference between a plant cell and an animal cell is that plant cells have chloroplasts.
False
Two different structures that all cells have are a cell membrane and a cell wall.
False
The packaging and distributing center of a cell
Golgi apparatus
Mitochondria's function in a cell
Make energy
Characteristic of prokaryotes
No nucleus evolved before eukaryotes
The double membrane surrounding the nucleus.
Nuclear envelope
One difference between eukaryotes and prokaryotes. Prokaryotes don't have this.
Nucleus
The structure that identifies a cell as a eukaryote
Nucleus
Where chromosomes are found in eukaryotic cells
Nucleus
A structure within a eukaryotic cell that performs a specific function.
Organelle
Eukaryotic cells have membrane-bound _____.
Organelles
The type of molecule that forms a lipid bilayer within the cell membrane.
Phospholipid
Proteins are made on these
Ribosomes
When the volume area of a cell increases, it's surface area increases at the _______ rate.
Slower
The function most effectively, a cell must be...
Small
The way chloroplasts are similar to mitochondria
They both contain DNA
Most of a cell's ATP is produced in the cell's mitochondria.
True
Organelles enable eukaryotic cells to carry out specialized functions.
True
Robert Hooke observed cork cells under a microscope.
True
The large membrane-bound space in which water, waste products, and nutrients can be stored. Found in plant cells.
Vacuole
