Biology Unit 2 Elephant Test Review

Front

In gel electrophoresis, where will the largest DNA fragment appear?

Back

The largest DNA fragment will appear closest to the starting wells.

Front

What organelle is responsible for photosynthesis and contains chlorophyll?

Back

Chloroplast.

Front

What is the function of a vacuole in plant and animal cells?

Back

Stores water and materials; animals have small vacuoles, while plants have a large central vacuole.

Front

True or False: Herbivores help increase the dispersal of seeds by releasing them in their fecal matter.

Back

True.

Front

What molecules make up cellulose, which constitutes almost all of a plant's mass?

Back

Glucose.

Front

What is the primary role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to convert carbon dioxide and water into glucose and oxygen.

Front

What is the process by which DNA fragments are separated by size?

Back

Gel electrophoresis.

Front

What is the main difference between plant and animal vacuoles?

Back

Plants have a large central vacuole, while animals have smaller vacuoles.

Front

What is the significance of glucose in plant structure?

Back

Glucose is a building block for cellulose, which provides structural support to plants.

Front

How do herbivores contribute to the ecosystem in terms of seed dispersal?

Back

Herbivores consume fruits and seeds, and their movement helps disperse seeds through their fecal matter.
