What is a Cell?

Question 1

What is a cell?

Answer 1

the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert
those nutrients into energy, and carry out specialized functions. Cells also contain the
body’s hereditary material and can make copies of themselves

Question 2

organelles

Answer 2

Cells have many parts, each with a different function- specialized structures that perform certain tasks within the cell;
- Cytoplasm
-Cytoskeleton
-Endoplasmic Reticulum
-Golgi Apparatus
- Lysosomes and peroxisomes
-Mitochondria
-Nucleus
-Plasma Membrane
-Ribosomes

Question 3

Cytoplasm

Answer 3

Within cells, the cytoplasm is made up of a jelly-like fluid (called the cytosol)
and other structures that surround the nucleus

Question 4

Cytoskeleton

Answer 4

The cytoskeleton is a network of long fibers that make up the cell’s structural framework.
The cytoskeleton has several critical functions, including determining cell shape,
participating in cell division, and allowing cells to move. It also provides a track-like
system that directs the movement of organelles and other substances within cells.

Question 5

Endoplasmic reticulum (ER)

Answer 5

This organelle helps process molecules created by the cell. The endoplasmic reticulum also transports these molecules to their specific destinations either inside or
outside the cell.

Question 6

Golgi apparatus

Answer 6

The Golgi apparatus packages molecules processed by the endoplasmic reticulum to be transported out of the cell. The Golgi apparatus is a structure in the cell cytoplasm

Question 7

Lysosomes and peroxisomes

Answer 7

These organelles are the recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances, and recycle worn-out cell
components. Lyosomes are cell structures in the cytoplasm.

Question 8

Mitochondria

Answer 8

Mitochondria are complex organelles that convert energy from food into a
form that the cell can use. They have their own genetic material, separate from the DNA
in the nucleus, and can make copies of themselves. Mitochondria are structures within the cell cytoplasm

Question 9

Nucleus

Answer 9

The nucleus serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’s hereditary material. The nucleus is surrounded by a membrane called the nuclear envelope, which protects the DNA and separates the nucleus from the rest of the cell. Central structure of the cell

Question 10

Plasma membrane

Answer 10

The plasma membrane is the outer lining of the cell. It separates the cell from
its environment and allows materials to enter and leave the cell. Surrounds a cell

Question 11

Ribosomes

Answer 11

Ribosomes are organelles that process the cell’s genetic instructions to
create proteins. These organelles can float freely in the cytoplasm or be connected to
the endoplasmic reticulum. Ribosomes are cell structures near the nucleus.
