Anatomy of a cell

Where does photosynthesis take place?

• Nucleus

• Mitochondrion

• Chloroplast

• Organelle

• Cell Membrane

Answer explanation

Photosynthesis occurs in the chloroplasts, which are specialized organelles in plant cells. They contain chlorophyll, the pigment that captures sunlight, enabling the conversion of light energy into chemical energy.

Which organelle produces energy?

• Nucleus

• Mitochondrion

• Chloroplast

• Organelle

• Cell Membrane

Answer explanation

The mitochondrion is known as the powerhouse of the cell, as it produces energy in the form of ATP through cellular respiration. The other organelles listed do not primarily function in energy production.

Which is considered the control center of the cell?

• Nucleus

• Mitochondrion

• Chloroplast

• Organelle

• Cell Membrane

Answer explanation

The nucleus is considered the control center of the cell because it houses the cell's genetic material and regulates gene expression, thereby controlling cellular activities and functions.

Any structure that is inside a cell that performs a specialized function is called...

• Nucleus

• Mitochondrion

• Chloroplast

• Organelle

• Cell Membrane

Answer explanation

Any structure within a cell that has a specific function is known as an organelle. Examples include the nucleus, mitochondrion, and chloroplast, but the term 'organelle' encompasses all such structures.

The selectively permeable organelle that protects the cell.

• Nucleus

• Mitochondrion

• Chloroplast

• Organelle

• Cell Membrane

Answer explanation

The cell membrane is a selectively permeable organelle that protects the cell by controlling what enters and exits, thus maintaining homeostasis. Other options like the nucleus and mitochondrion serve different functions.

Which two organelles do animal cells NOT have?

• cell membrane

• cell wall

• mitochondrion

• chloroplast

Answer explanation

Animal cells lack chloroplasts and a cell wall. Chloroplasts are involved in photosynthesis, which is not a function of animal cells, while the cell wall is a rigid structure found in plant cells, providing support.

What provides support and allows plants to stand upright?

• cell membrane

• organelles

• cell wall

• nucleus

Answer explanation

The cell wall provides structural support to plants, allowing them to stand upright. It is a rigid layer that surrounds the cell membrane, giving plants their shape and strength.

The nucleus contains the genetic material within a cell.

• True

• False

Answer explanation

True. The nucleus is the cell's control center and houses the genetic material (DNA), which is essential for cell function and heredity.

The vacuole contains the genetic material within a cell.

• True

• False

Answer explanation

The vacuole does not contain genetic material; instead, the genetic material is found in the nucleus of the cell. Therefore, the statement is false.

Every organelle has a specific _________.

• function.

• structure.

Answer explanation

Every organelle has a specific function that contributes to the overall operation of the cell. While structure is important, it is the function that defines the role of each organelle.
