The organelle where ribosomes are made, synthesized and partially assembled, located in the
nucleus Nucleolus
the readily stainable substance of a cell nucleus consisting of DNA and RNA and various
proteins Chromatin
**What is the primary function of the nucleus in both plant and animal cells?**
It houses the cell's genetic material (DNA) and regulates cellular activities.
**Which organelle is responsible for generating energy in the form of ATP and is known as the
"powerhouse" of the cell?**
Mitochondria
**What structure surrounds both plant and animal cells, controlling the passage of substances in
and out of the cell?**
Cell membrane
**In plant cells, what additional structure provides support and protection that is not found in
animal cells?**
1
, Cell wall
**Where in the plant cell does photosynthesis occur, converting sunlight into chemical
energy?**
Chloroplasts
**What is the jelly-like substance in which all organelles are suspended within the cell?**
Cytoplasm
**What organelle is responsible for protein synthesis and can be found floating freely or attached
to the rough endoplasmic reticulum?**
Ribosomes
**What is the role of the rough endoplasmic reticulum?**
It synthesizes and folds proteins, with ribosomes attached to its surface.
**What is the function of the smooth endoplasmic reticulum?**
It synthesizes lipids and helps detoxify the cell.
**What organelle is responsible for modifying, packaging, and shipping proteins and lipids
throughout the cell?**
Golgi apparatus
