According to the ingestion section, what is ingestion?

the taking in of food and water

breaking down food into small molecules that can be used by the cell

According to the reproduction slide, which option matches the description “…or asexual. (autosomes) aka somatic”?

Asexual reproduction involves somatic cells rather than gametes

Sexual reproduction uses autosomes instead of gametes

Irritability describes asexual cell division

Secretion is another term for sexual reproduction

On the slide that shows a plant sprig and the heading Irritability, what does irritability mean?

Using food energy for growth and repair

The removal of liquid waste from the cell

On the slide that shows a snail trail under the heading Secretion, which statement best defines secretion?

A made substance in one place, but used in another

The movement of materials inside a cell

The removal of solid waste from the cell

Select all statements that describe prokaryotic cells as shown on the Prokaryotic Cells slide with a single rod‑shaped cell image.

They lack a nucleus and membrane‑bound organelles

Their DNA is not inside a nucleus and is not separated by a membrane

They are generally smaller and simpler than eukaryotic cells

They contain mitochondria and chloroplasts

According to the slide, bacteria are what type of cells?

Both prokaryotic and eukaryotic

According to the Endosymbiotic Theory shown, what happened to the mitochondria and chloroplast?

They were once simple prokaryotes that were engulfed by larger prokaryotes and survived inside them.

They formed directly from the infolding of the plasma membrane that created the nucleus.

They are modified ribosomes that became membrane‑bound over time.

They developed from pieces of the cell wall that detached and became organelles.

Which statement best describes the nucleus according to the passage: “The nucleus is the control center of the cell” and “The nucleus contains nearly all of the cell’s DNA”?

It stores most genetic material and directs cell functions

It digests waste and stores water

It packages proteins for secretion only

It produces ATP for the cell exclusively

According to the description, what is the primary function of the pores in the nuclear membrane?

They allow materials to move into and out of the nucleus

They attach ribosomes to the outer membrane

They create ATP for nuclear reactions

They permanently seal the nucleus from the cytoplasm

Which molecules are specifically stated to be contained in the nucleus?

Only proteins used in ribosomes

What are the two functions of chromosomes as described?

Contain genetic information passed from one generation to the next

Control the cell’s activities

Provide structural support to the cell membrane only

What is the nucleoplasm?

The semi-liquid portion inside the nucleus

The double membrane surrounding the nucleus

The protein complex that makes ATP

The space between the cell membrane and the wall

What does the nucleolus manufacture?

The subunits that make up ribosomes

Stacks of flattened membranes that sort proteins

How many subunits are described for a ribosome, and what happens to them after leaving the nucleus?

Two subunits; they pass through nuclear pores to the cytoplasm where they combine to form ribosomes

Three subunits; they remain inside the nucleus to make ribosomes

One subunit; it attaches to the nuclear membrane permanently

Four subunits; they fuse with the Golgi apparatus

Which statements are identified as functions of the nucleus?

Carrier of genetic information because genes are found there

Controls the reproduction of the cell

Directs protein synthesis by sending messages to ribosomes

Stores digestive enzymes to break down waste
