What happens to sister chromatids during anaphase?
Sister chromatids separate at the centromere
Each chromatid is now a complete chromosome.
What are the parts of a microscope?
- Tube
- Base
- Ocular lens
These components are essential for the functioning of a microscope.
What are the stages of mitosis?
- Prophase
- Metaphase
- Anaphase
- Telophase
Each stage plays a crucial role in cell division.
Why is DNA located in the nucleus?
- Keeps DNA in one place
- Keeps DNA safe
This organization protects genetic material from damage.
What is the function of the rough endoplasmic reticulum (RER)?
Makes proteins
The RER is distinguished by the presence of ribosomes.
What does the smooth endoplasmic reticulum (SER) produce?
Makes lipids (fats) and oils
Unlike the RER, the SER does not have ribosomes.
What is the role of lysosomes?
- Filled with enzymes
- Where digestion happens
- Breaks down invading bacteria and damaged cell organelles
Lysosomes are essential for cellular digestion and waste management.
What is the job of the Golgi body?
Sorts proteins and sends them to their destinations
It receives proteins from the endoplasmic reticulum and packages lipids.
What are the stages of interphase?
- G1
- S
- G2
Interphase is critical for cell growth and DNA replication.
What occurs during metaphase?
Chromosomes line up in the middle of the cell
This alignment is crucial for proper chromosome separation.
What happens during anaphase?
Chromatids separate at the centromere and move to opposite ends of the cell
Each chromatid is now a complete chromosome.
What is cytokinesis?
The process of splitting the cytoplasm
In plant cells, this involves the formation of a cell plate.
What occurs during telophase?
- Mitotic spindle breaks down
- Two new nuclei form
This marks the near end of mitosis.
Fill in the blank: The process of splitting the cytoplasm is known as _______.
Cytokinesis
This process is crucial for the formation of two daughter cells.
True or False: The cell membrane pinches in half during cytokinesis.
True
This pinching is essential for creating separate daughter cells.
What forms the cell wall in plant cells during cytokinesis?
Cell plate
The cell plate develops into the cell wall as the new cells form.
