Lesson 2 Flashcards
What is the function of the nucleus in a cell?
The nucleus controls cell activities and houses genetic material (DNA).
True or False: Mitochondria are known as the powerhouse of the cell.
True
Fill in the blank: The _______ is responsible for photosynthesis in plant cells.
chloroplast
What is the main function of the endoplasmic reticulum (ER)?
The ER synthesizes proteins and lipids.
Which organelle is involved in packaging and distributing proteins?
Golgi apparatus
True or False: Ribosomes can be found on the rough endoplasmic reticulum.
True
What structure provides support and protection to plant cells?
Cell wall
What is the function of lysosomes?
Lysosomes contain enzymes that break down waste materials and cellular debris.
Multiple Choice: Which organelle is responsible for energy production?
Mitochondria
Define the function of the plasma membrane.
The plasma membrane regulates the movement of substances in and out of the cell.
Fill in the blank: The _______ is a jelly-like substance that fills the cell.
cytoplasm
Which organelle is primarily involved in detoxifying harmful substances?
Smooth endoplasmic reticulum
True or False: Plant cells do not contain mitochondria.
False
What is the role of vacuoles in plant cells?
Vacuoles store nutrients, waste products, and help maintain turgor pressure.
Multiple Choice: Which of the following is unique to plant cells?
Chloroplasts
What is the primary function of the cytoskeleton?
The cytoskeleton provides structural support and helps in cell movement.
Fill in the blank: The _______ is involved in the synthesis of ribosomal RNA.
nucleolus
Which organelle is known for modifying, sorting, and packaging proteins?
Golgi apparatus
True or False: Centrioles are found in both plant and animal cells.
False
What is the function of peroxisomes?
Peroxisomes break down fatty acids and detoxify harmful byproducts.
