Parts Of An Animal Cell

1. Where is most of the cell's DNA located?

CYTOPLASM

MITOCHONDRIA

CELL MEMBRANE

NUCLEUS

The majority of a cell's DNA is located in the nucleus, where it is stored and protected within the nucleus membrane. While DNA can be found in other organelles like mitochondria, the nucleus is the primary location for genetic material in a cell.

2. Which structure serves as the double layer of membrane that regulates transport of substances between the nucleus and cytoplasm?

Nuclear Pore Complex

Endoplasmic Reticulum

Golgi Apparatus

NUCLEAR ENVELOPE

The nuclear envelope acts as a barrier between the nucleus and cytoplasm, controlling the flow of molecules in and out of the nucleus.

3. What is the site of protein manufacture in a cell; may be free floating or attached to the rough ER?

RIBOSOME

Lysosome

Golgi Apparatus

Mitochondria

Ribosomes are the sites of protein synthesis in a cell, either free in the cytoplasm or attached to the rough endoplasmic reticulum. Golgi Apparatus, Mitochondria, and Lysosome are organelles in a cell with different functions unrelated to protein manufacture.

4. What is a network of fibers that provides support and aids movement?

Endoplasmic Reticulum

Ribosomes

CYTOSKELETON

Mitochondria

The cytoskeleton is a network of fibers within a cell that provides structural support and aids in cellular movement. Mitochondria are organelles responsible for producing energy, ribosomes are responsible for protein synthesis, and the endoplasmic reticulum is involved in protein and lipid synthesis and packaging.

5. Which organelle is responsible for the manufacturing site of a wide variety of cellular products?

Golgi Apparatus

ENDOPLASMIC RETICULUM (ER)[CONSISTS OF 'SMOOTH' AND 'ROUGH' ER]

Nucleus

Mitochondria

The endoplasmic reticulum (ER), which consists of smooth and rough ER, is the organelle responsible for the manufacturing site of a wide variety of cellular products. The Golgi Apparatus is involved in processing and packaging cellular products, the nucleus contains genetic material, and mitochondria is known as the powerhouse of the cell.
