Definitions
What is a nucleolus?
A structure within the nucleus that creates ribosomes.
Are peroxisomes located in animal cells, plant cells, or both?
Peroxisomes are found in both animal and plant cells.
What are some characteristics of the rough ER?
- Bumpy appearance
- Works/connected with nucleus
Why do plants have one large vacuole while animals have multiple small ones?
Plants only have one large vacuole for turgor pressure and waste management as they are stationary, while animals have numerous small vacuoles as they perform different tasks and do not require a rigid structure as they are mobile.
What is the Golgi Apparatus?
The Golgi Apparatus modifies, packages, and sends off proteins/lipids from ER into vesicles for delivery.
Are centrioles located in animal cells, plant cells, or both?
Centrioles are located only in animal cells.
What are some characteristics of chromosomes?
- Has hereditary information
- Tightly packed DNA
What makes the rough ER appear bumpy?
Rough ER are studded with ribosomes, causing it to appear bumpy.
What is a mitochondria?
The mitochondria powers the cell by producing ATP (energy) through cellular respiration.
Is the cell membrane located in animal cells, plant cells, or both?
The cell membrane is found in both animal and plant cells.
What are some characteristics of ribosomes?
- Can float freely
- Can attach to the rough ER
- Is made up of RNA and proteins.
What is the primary difference between the nucleus and nucleolus?
The nucleus is the big organelle containing cell DNA and acts as the control center, while the nucleolus is a smaller and denser structure within the nucleus.
What are lysosomes?
Lysosomes break down waste and other old cell parts.
Are cillia located in animal cells, plant cells, or both?
Located in both animal and plant cells.
What are some characteristics of the vacuole?
- Plants have one big central vacuole, while animals have multiple small ones
- Maintains pressure in plant cells
What is the main difference between eukaryotic and prokaryotic cells?
What is the cytoskeleton?
The cytoskeleton is a protein network that provides structure and support to the cell.
Are gap junctions located in animal cells, plant cells, or both?
Gap junctions are located only in animal cells.
What are some characteristics of the Golgi Apparatus?
- They are stacked membranes and can seem like stacked pancakes
- They create vesicles
Think of an analogy that could work for gap junctions.
