Two organelles not visible in an onion cell are the centrioles and lysosomes. Centrioles are involved in cell division and are not present in plant cells like onion cells. Lysosomes are membrane-bound organelles that contain digestive enzymes and are more commonly found in animal cells.
chloroplast and cell wall
Cell wall and chloroplasts.
No, organelles are not made during growth phase 2 (G2) of the cell cycle. This phase is mainly focused on preparing the cell for division by synthesizing proteins and organelles are generally not synthesized during this time.
The two cell organelles that have DNA are the mitochondria and the chloroplasts. Mitochondria are responsible for producing energy in the cell, while chloroplasts are found in plant cells and are responsible for photosynthesis.
The two organelles that plant cells have that animal cells lack are: 1. Cell wall 2. Vacuole.
