Which two organelles/structures are found in plant cells but not in animal cells?
A
Chloroplasts and a cellulose cell wall
B
Mitochondria and a nucleus
C
Lysosomes and centrioles
D
Rough endoplasmic reticulum and Golgi apparatus
Verified step by step guidance1
Step 1: Understand the question is asking to identify organelles or structures unique to plant cells and absent in animal cells.
Step 2: Recall that chloroplasts are organelles responsible for photosynthesis and are found only in plant cells, not in animal cells.
Step 3: Remember that plant cells have a rigid cell wall made of cellulose, which provides structural support and is absent in animal cells.
Step 4: Recognize that mitochondria and nucleus are found in both plant and animal cells, so they are not unique to plant cells.
Step 5: Note that lysosomes, centrioles, rough endoplasmic reticulum, and Golgi apparatus are present in animal cells as well, so they are not unique to plant cells.
