Lesson 2: Plant And Animal Cells Organelles Flashcards
What is the function of the nucleus in a cell?
The nucleus controls the cell’s activities and contains the genetic material (DNA).
True or False: Mitochondria are known as the powerhouse of the cell.
True
Fill in the blank: The _______ is responsible for protein synthesis in the cell.
ribosome
Which organelle is involved in photosynthesis in plant cells?
chloroplast
What is the main function of the cell membrane?
The cell membrane controls the movement of substances in and out of the cell.
Multiple Choice: What is the role of the endoplasmic reticulum (ER)? A) Energy production B) Protein and lipid synthesis C) Genetic information storage
B) Protein and lipid synthesis
What structure provides support and shape to plant cells?
cell wall
True or False: Lysosomes are involved in the digestion of waste materials in the cell.
True
What is the function of the Golgi apparatus?
The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or use within the cell.
Fill in the blank: The _______ is a network of protein filaments that helps the cell maintain its shape.
cytoskeleton
Which organelle is responsible for detoxifying harmful substances in the cell?
peroxisome
Multiple Choice: Which of the following is NOT a function of the vacuole? A) Storage B) Waste disposal C) Photosynthesis
C) Photosynthesis
What is the role of the plasma membrane in plant and animal cells?
The plasma membrane regulates what enters and exits the cell, providing protection and support.
True or False: Ribosomes can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum.
True
What are the two types of endoplasmic reticulum?
Rough ER and Smooth ER
Fill in the blank: _______ are membrane-bound organelles that contain enzymes for digestion.
Lysosomes
What is the primary function of chloroplasts?
Chloroplasts convert sunlight into chemical energy through photosynthesis.
Multiple Choice: Which organelle is known for packaging and transporting proteins? A) Lysosome B) Golgi apparatus C) Nucleus
B) Golgi apparatus
What is the function of the cytoplasm?
The cytoplasm is the gel-like substance that fills the cell and holds the organelles in place.
True or False: Animal cells have a cell wall.
False
